A technician uses a software application on a smartphone, tablet, or other portable device to communicate with the motor controller via a wireless communication device incorporated into the motor assembly. The smartphone may receive relevant information, such as identification, programming, or diagnostic information, and process the information or wirelessly transmit the information to a server for processing. Based on the information, the smartphone may transmit programming instructions to the motor controller via the wireless communication device. Further, the wireless communication device may transmit sensor data associated with the motor to allow for monitoring the motor's performance.
Description
FIELD

The present invention relates to systems and methods for managing electric motors, and more particularly, embodiments concern a system and method for wirelessly communicating with an electric motor in order to identify a suitable replacement for, program, monitor and/or diagnose, and/or tune or otherwise reprogram the motor without physically connecting to the motor.


BACKGROUND

Electric motors, such as are used in heating, ventilation, and air conditioning (HVAC) systems, fluid circulation systems, and other systems, often must be programmed to operate according to the specific needs of these systems. The motors are programmed using a specialized motor programming computer at a motor manufacturing facility, at the point of sale, or at an assembly plant. Programming a motor that is already onsite requires a technician to return the motor to the motor manufacturing facility or to another designated programming site that has the necessary specialized motor programming computer. Similarly, motors at inventory sites that do not have a specialized motor programming computer must be sent back to the motor manufacturing facility to be programmed for their selected applications.


After they leave the manufacturing facility, motors occasionally have to be reprogrammed or tuned, diagnosed, or replaced with new motors when they malfunction or otherwise no longer work properly or optimally. A technician performing such work is required to have or obtain and carry a programming tool, including a connector, suitable for physically connecting to and interfacing with the specific motor or the specific type of motor at issue. For example, a technician arriving on-site with a replacement motor can either extract the programmed parameters from the existing motor or download the correct information, if available, from a database using wireless communication. However, both options require the technician to have or obtain and carry the proper programming tool, including a connector for physically connecting to the existing and/or replacement motors to accomplish the task. Different motors, different types of motors, or different brands of motors may require different programming tools, particularly different physical connectors, and having or obtaining and carrying the several different physical connectors that may be needed increases the cost and time required to perform the work. Further, motors, especially motors that are incorporated into larger systems, may be difficult to access in order to make the required physical connections, and dismantling the larger systems in order to gain such access can further increase the cost and time needed to perform the work.


SUMMARY

Embodiments of the present invention solve the above-described and other problems by providing a system and method for wirelessly communicating with an HVAC or other electric motor in order to identify a suitable replacement for, program, monitor and/or diagnose, and/or tune or otherwise reprogram the motor without physically connecting to the motor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The following detailed description of the invention references the accompanying drawings that illustrate specific embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense.


In this description, references to “one embodiment,” “an embodiment,” or “embodiments” mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to “one embodiment,” “an embodiment,” or “embodiments” in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the present technology can include a variety of combinations and/or integrations of the embodiments described herein.


Embodiments of the present invention provide a system and method for wirelessly communicating with an HVAC or other electric motor in order to identify a suitable replacement for, program, monitor and/or diagnose, and/or tune or otherwise reprogram the motor without physically connecting to the motor. More specifically, wireless communication devices (i.e., transceivers) and programming software are incorporated into the motor assemblies and are accessible by technicians using portable computing and/or mobile communication devices, thereby reducing or eliminating the need for technicians to have and carry programming tools, reducing or eliminating the need to physically access the motors, and reducing or eliminating the need for the motors to include interface boxes for physically connecting with connectors for wiredly communicating signals. Further, the incorporated wireless communication devices facilitate interfacing with motor sensors (e.g., wireless Bluetooth temperature, humidity, pressure, and/or air sensors) whenever desired, and providing the information from such sensors to internal or external monitoring and/or control systems. Still further, the motors themselves may be used as sensors for sensing the performance of the larger systems of which the motors are a part. Embodiments may be used with motors designed for HVAC systems, refrigeration systems, washing machines, dishwashers, or any other electrically-powered devices or systems.


In one exemplary application of the present technology, a technician may replace an original or otherwise existing motor that can no longer be viably serviced. The technician may carry in their service vehicle a small number of replacement motors from which they may select the replacement motor that best or most effectively emulates the existing motor. To select the correct replacement motor, the technician may use a portable electronic communication device (e.g., a smartphone) to wirelessly retrieve motor information from the existing motor and wirelessly access operating parameters and motor data stored on a server over a wireless communication network. The server may identify a recommended replacement motor and transmit the recommendation to the technician's portable electronic communication device. The technician may use the motor recommendation to select the replacement motor from the replacement motors on hand and replace the existing motor with the replacement motor. The technician may establish a wireless connection between the portable electronic communication device and a wireless communication device incorporated into, onto, adjacent to, or otherwise similarly associated with the replacement motor to wirelessly program the replacement motor to sufficiently emulate the performance of the existing motor.


The present invention may be used with substantially any suitable type of electric motors. The motors may operate on direct current (DC) or alternating current (AC), may be synchronous or asynchronous, and may be single phase or three phase. The motors may be of any type, including but not limited to, permanent split capacitor (PSC) motors, brushed DC motors, switched reluctance motors, coreless or ironless DC motors, series wound universal motors, induction motors, torque motors, or stepper motors. Moreover, the motors may be fixed speed, multi-speed, or variable speed and may have any horsepower (HP) rating.


The motors may have integral or separate motor controllers that provide power to and control operation of one or more of the motors. Each such motor controller may include any combination of circuitry, hardware, firmware, and/or software. The motors may be replaceable with replacement motors that may be programmable to sufficiently emulate or improve upon the operating parameters of the motors they are replacing. One replacement motor may be programmable to replace two, five, ten, or more different types of motors. However, the principles of the present invention are not limited to any particular motor type, technology, or size. The replacement motors may have integral or separate motor controllers that provide power to and control operation of one or more of the motors. Again, each such motor controller may include any combination of circuitry, hardware, firmware, and/or software.


Referring to FIG. 1, an embodiment of a motor programming system 10 is shown along with original or otherwise existing, new, and replacement motors 12, 14, 16, but the principles of the invention are applicable to any number and type of motors. Each motor 12, 14, 16 may be provided with its own or a shared motor controller 18 having a microprocessor 22 for controlling operation of the motor. The motor programming system 10 may include one or more servers 20, one or more portable electronic devices 24, 26, 28, one or more wireless communication devices 32 incorporated into, onto, adjacent to, or otherwise similarly associated with the motor controller 18, and a mobile motor servicing software application 30 running on the portable electronic devices 24, 26, 28. The server 20 and portable electronic devices 24, 26, 28 may be operated by any persons or entities. For example, the server 20 may be operated by system administrators, and the portable electronic devices 24, 26, 28 may be operated by motor installers, service technicians, or property owners who replace motors in HVAC systems, washing machines, dishwashers, or any other electrical device or larger system into which the motor may be incorporated.


The components of the motor programming system 10 illustrated and described herein are merely examples of equipment that may be used to implement embodiments of the present invention and may be substituted with other equipment without departing from the scope of the present invention. Some of the illustrated components of the system 10 may also be combined and/or may be operated by the same persons or entities. Similarly, some aspects of the invention performed with the portable electronic devices 24, 26, 28 may be performed with the server 20 and vice versa.


In more detail, the server 20 electronically stores and/or otherwise has electronic access to selection information for selecting replacement motors, programming information for programming motors, diagnostic information for diagnosing performance problems with motors, recommendation information for recommending actions for addressing performance problems with motors, evaluation information for evaluating the performance of larger systems into which motors are incorporated, and recommendation information for recommending actions for tuning motors to their larger systems. Any or all such information may be in any suitable form and format, such look-up or other tables, decision trees, and/or machine learning abilities. The server 20 may also implement one or more computer programs for performing some of the functions described herein and may provide a web-based portal that can be accessed by the portable electronic devices 24, 26, 28 and other computers. Embodiments of the server 20 may include one or more servers running Windows; LAMP (Linux, Apache HTTP server, MySQL, and PHP/Perl/Python); Java; AJAX; NT; Novel Netware; Unix; Mac OS; or any other software system. The server 20 includes or has access to computer memory and other hardware and software for receiving, storing, accessing, and transmitting information via a wireless communication network 33 as described below. The server 20 may also include conventional web hosting operating software, searching algorithms, and an Internet connection, and are assigned URLs and corresponding domain names so that they can be accessed via the Internet in a conventional manner.


The portable computing devices 24, 26, 28 may be any devices used by motor installers, service technicians, or others while managing (e.g., replacing, programming, diagnosing, and/or tuning) the operation of motors in HVAC systems or other electrically-powered devices or systems. The portable electronic devices 24, 26, 28 may be any type of mobile smartphone, handheld device, tablet, laptop computer, or portable gaming system. The portable electronic devices 24, 26, 28 may each include a touch screen display or a visual display with button inputs and further include computing hardware, software, memory, including hardware and software for wirelessly communicating electronic signals. The portable electronic devices 24, 26, 28 may each include or can access an Internet browser and a conventional Internet connection such as a wireless broadband connection, DSL converter, or ISDN converter so that it can receive communication from the server 20 via the communication network 33 described below.


Referring also to FIGS. 2 and 3, the wireless communication device 32 may be incorporated into the existing and/or the replacement motor controller 18, and configured to wirelessly communicate with the portable electronic device 24, 26, 28 and may include a transceiver 34 and a communication controller 36. The housing of the motor controller 18 may be attached to the housing of the motor 12, 14, 16, as shown in FIG. 2, or the housing of the motor controller 18 may be detached from the housing of the motor 12, 14, 16 with the motor controller 18 connected to the motor by one or more electrical wires, as shown in FIG. 3. The transceiver 34 may wirelessly transmit signals to and receive signals from the portable electronic device 24, 26, 28 via substantially any suitable communication technology, such as a Bluetooth, radio frequency, 3G, 4G, 5G, or near field technology connection. The communication controller 36 may direct the wireless signals received from the portable electronic device 24, 26, 28 and the signals sent from the motor controller of the motor 12 and may be or include a microprocessor, a communication bus, a router, or other signal control device. Components of the system 10 that are incorporated into the motor controller 18, such as the wireless communication device 32, and that require power may receive power from the same source and/or subsystem (e.g., the motor controller 18) that provides power to the motor 12.


Unlike prior art systems, neither a physical communication connector nor an interface box is required to communicate with or program the motor 12, 14, 16. Thus, the associated cables, wires, pins, pin receivers, clips, plugs, or other connection points such as a 4-wire, 16-pin, or serial communication connector may be eliminated. In one implementation, the motors 12, 14, 16 may retain the interface box for other purposes or as a back-up, and the wireless communication device 32 may be incorporated into the interface box.


The mobile motor servicing software application 30 may be stored on and executed by any of the portable electronic devices 24, 26, 28. An embodiment of the mobile motor servicing software application 30 may broadly include the graphical user interface and executable computer code for implementing aspects of the invention. The graphical user interface may include virtual images, text, text input boxes, checkboxes, buttons, and other user-selectable inputs. The graphical user interface may have a layout that mimics the look of motor controls of the motor 12, 14, 16 or of a conventional interface box of a motor and may also include user instructions in the form of text, icons, images, videos, and other visual cues.


The executable computer code may be provided for implementing logical functions in the portable electronic devices 24, 26, 28 and can be embodied in any non-transitory computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as the portable electronic devices 24, 26, 28, a processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device, and execute the instructions. In the context of this application, a “non-transitory computer-readable medium” can be any non-transitory memory that can contain, store, or communicate the programs. The non-transitory computer-readable medium can be, for example, but not limited to, an electronic, magnetic, optical, electro-magnetic, infrared, or semi-conductor system, apparatus, or device. More specific, although not inclusive, examples of the non-transitory computer-readable medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a random access memory (RAM), a read-only memory (ROM), an erasable, programmable, read-only memory (EPROM or Flash memory), an optical fiber, and a portable compact disk read-only memory (CDROM). The mobile applications or computer programs may be distributed between portable electronic devices or may be downloaded from a virtual application marketplace such as the App Store and Google Play. The mobile motor servicing software application 30 may be stored on the non-transitory memory of the portable electronic devices 24, 26, 28 or may reside on one of the server 20 and can be accessed over a wireless internet connection.


The communication network 33 may be the Internet or substantially any other suitable communication network such as a local area network, a wide area network, or an intranet. The communication network 33 may include or be in communication with a wireless network capable of supporting wireless communication such as the wireless networks operated by AT&T, Verizon, or Sprint. The communication network 33 may also be combined or implemented with several different networks.


Referring to FIG. 4, a method of wirelessly selecting and programming a replacement motor 16 for replacing an existing motor 12 using the system 10 is shown. Some of the blocks of the flow diagram may represent a step or steps in a method or a module segment or portion of code of the mobile applications and computer programs of the present invention. In some alternative implementations, the functions noted in the various blocks may occur in a different order than is depicted in FIG. 4. For example, two blocks shown in succession in FIG. 4 may in fact be executed substantially concurrently, or the blocks may sometimes be executed in reverse order depending upon the functionality involved.


A service technician may establish a wireless connection between the portable electronic device 24 and the wireless communication device 32 incorporated into the existing motor assembly to be replaced, as shown in block 104. The mobile motor servicing software application 30 on the portable electronic device 24 may display an indication that a wireless connection has been made and may display a current status of the existing motor 12 such as “operational” or “standby.” The wireless communication device 32 may wirelessly transmit identification, set-up, and/or programming information for the existing motor 12 such as a model number, horsepower (HP) rating, input voltage, manufacturer name, and/or other motor information to the portable electronic device 24 over the Bluetooth or other wireless connection, as shown in block 106. The graphical user interface of the portable electronic device 24 may display the information. The portable electronic device 24 may wirelessly transmit the motor information to the server 20, as shown in block 108. The motor information may be transmitted automatically or after the technician initiates the motor information transmission.


The server 20 may receive the motor information and compare the motor information to motor operating parameters and motor data of a number of motors stored on its memory to identify the existing motor 12, as shown in block 110. For example, the server 20 may use a manufacturer name and a HP rating of the existing motor 12 to determine a model number of the existing motor 12. The server 20 may identify the replacement motor 16 from the available replacement motors that most closely or most effectively can emulate or improve upon the operation of existing motor 12, and generate a motor recommendation representative of the replacement motor, as shown in block 112. For example, the server 20 may identify the replacement motor 16 that has the same input voltage as the existing motor 12 and that has the smallest HP range that includes the HP rating of the existing motor 12. The replacement motor recommendation may be a model number, a brand name, a motor operating parameter, or any other information that identifies a suitable replacement motor and may include installation instructions for aiding the technician in installing the replacement motor.


The server 20 may also generate motor programming instructions based on the motor information, as shown in block 114. Alternatively, the server 20 may retrieve motor programming instructions that have been designated for emulating the existing motor 12. The motor programming instructions may be machine-readable computer data or may be in human readable form. The server 20 may wirelessly transmit the replacement motor recommendation and the motor programming instructions to the portable electronic device 24, as shown in block 116.


The technician may input additional motor programming instructions into the mobile motor servicing software application 30 via the graphical user interface 40, as shown in block 118. The additional motor programming instructions may be used for overriding and/or supplementing parts of the motor programming instructions transmitted from the server 20. The technician may use the replacement motor recommendation to select the replacement motor 16, and install the replacement motor 16 in place of the existing motor 12, as shown in block 120. The graphical user interface of the mobile motor servicing software application 30 may display installation instructions transmitted with the replacement motor recommendation to aid the technician in installing the replacement motor 16. The technician may use the portable electronic device 24 to wirelessly transmit the motor programming instructions to the wireless communication device 32 incorporated into, onto, adjacent to, or otherwise similarly associated with the replacement motor 16, which passes the motor programming instructions to the microprocessor 22 of the controller 18 of the replacement motor 16, as shown in block 124.


The motor programming instructions may then be stored on the memory of the replacement motor's controller 18, as shown in block 126. The replacement motor's controller 18 may reference the motor programming instructions and instruct the replacement motor 16 to operate in the same way as the existing motor 12. For example, the controller 18 may instruct the replacement motor 16 to operate at the same operating speed and torque as the existing motor 12.


The above-described systems and methods for wirelessly programming a replacement motor for replacing an existing motor provide several advantages over conventional systems for selecting and programming replacement motors. For example, a technician can stock a few motors suitable for use in many applications and does not need to transport or have access to large inventories of motors for selecting a suitable replacement motor. The technician can use their own or a readily available portable electronic device to program the motor and does not need to take the motor to a location with a specialized motor programming computer. Further, the technician does not need to have and carry programing tools, such as wireless communication devices and connectors for physically connecting to the existing and/or replacement motor. Further, the incorporated wireless communication devices facilitate interfacing with motor sensors whenever desired.


An aftermarket dealer or an original equipment manufacturer (OEM) can also more conveniently program the replacement motor 16 at the point of purchase or at the point of assembly without sending the motor back to the manufacturing facility. Also, the aftermarket dealer or OEM can stock a few multi-purpose motors instead of stocking large inventories of limited purpose motors.


Referring to FIG. 5, a method of wirelessly monitoring, diagnosing, or otherwise determining a performance of a motor a motor 12 using the system 10, particularly the mobile motor servicing software application 30 on the portable electronic device 24, is shown. Some of the blocks of the flow diagram may represent a step or steps in a method or a module segment or portion of code of the mobile applications and computer programs of the present invention. In some alternative implementations, the functions noted in the various blocks may occur out of the order depicted in FIG. 5. For example, two blocks shown in succession in FIG. 5 may in fact be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order depending upon the functionality involved.


A service technician may establish a wireless connection between the portable electronic device 24 and the wireless communication device 32, as shown in block 204. The mobile motor servicing software application 30 on the portable electronic device 24 may display an indication that a wireless connection has been made. The wireless communication device 32 may transmit identification, set-up, and/or programming information about the motor 12 such as a model number, HP rating, input voltage, manufacturer name, and other motor information to the portable electronic device 24 via the Bluetooth or other wireless connection. The graphical user interface of the mobile motor servicing software application 30 may display the motor information on the display screen of the portable electronic device 24.


The wireless communication device 32 may transmit a wireless signal representative of a motor controller error, a mechanical failure, an electrical failure, or other issue to the portable electronic device 24 over the Bluetooth or other wireless connection, as shown in block 206. The information in the wireless signal may be a nonhuman-readable diagnostic code or a proprietary code indicative of the motor issue. The wireless communication device 32 may also transmit motor operating history data stored on the memory of the motor controller 18 to the portable electronic device 24, as shown in block 208. The motor operating history data may contain useful diagnostic information about the performance of the motor 12 such as operating hours, peak voltages, and operating temperatures.


The mobile motor servicing software application 30 may interpret and analyze or transmit to the server computer 20,22 for interpretation and analysis the information representative of the motor issue and/or the motor operating data to diagnose the motor issue, as shown in block 210. For example, the mobile motor servicing software application 30 or the server computer 20,22 may interpret a code in the wireless signal to represent an electrical short or an imbalanced motor. The mobile motor servicing software application 30 or the server computer 20,22 may compare recorded voltage data to determine that the motor 12 is frequently receiving overvoltages. The mobile motor servicing software application 30 or the server computer 20,22 may generate an error message or a diagnostic report based on the above analysis and display or transmit for display the error message or diagnostic report via the graphical user interface 40, as shown in block 212. For example, the error message may indicate that the motor issue could not be determined. The diagnostic report may indicate that the motor 12 is in danger of overheating or that the wiring insulation of the motor 12 may be at the end of its expected life cycle.


The mobile motor servicing software application 30 or the server computer 20,22 may generate or retrieve from memory a recommendation for fixing or replacing the motor 12 based on the above analysis, as shown in block 214. The graphical user interface of the mobile motor servicing software application 30 may display the recommendation on the display screen of the portable electronic device 24. Alternatively, the mobile motor servicing software application 30 may retrieve a recommendation for fixing or replacing the motor 12 from memory or the memory of the server computer 20,22 that has been determined to be the best solution for fixing or replacing the motor 12.


The above-described systems and methods for wirelessly servicing motors via a portable electronic device 24 provide several advantages over conventional systems for servicing motors. For example, a technician can diagnose a motor without carrying different types of motor diagnostic tools and adaptors or wireless communication devices and connectors for physically connecting to the motor. Further, the incorporated wireless communication devices facilitate interfacing with motor sensors whenever desired.


A person such as a homeowner can also use the systems and methods of the present invention to diagnose the motor without requesting the assistance of a technician. This allows the homeowner to immediately address critical HVAC or pump issues such as when a heater motor malfunctions during the winter.


Referring to FIG. 6, a method of wirelessly tuning or otherwise reprogramming a motor 12 using the system 10, particularly the mobile motor servicing software application 30 on the portable electronic device 24, is shown. Some of the blocks of the flow diagram may represent a step or steps in a method or a module segment or portion of code of the mobile applications and computer programs of the present invention. In some alternative implementations, the functions noted in the various blocks may occur out of the order depicted in FIG. 6. For example, two blocks shown in succession in FIG. 6 may in fact be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order depending upon the functionality involved.


For example, it will be understood that a normal control signal may be one of five Tap selections that typically are programmed at the factory. For example, Tap 1 through Tap 5 may respectively provide sixty, seventy, eighty, ninety, and one hundred percent (60%, 70%, 80%0, 90%, and 100%) motor torque depending on the requirements of the larger system of which the motor is a part. At various locations outside of the factory it may be desirable to reprogram one or more of the Tap selections for the purposes of tuning the motor to the larger system under repair. The motor controller microprocessor 22 may be capable of either independently or simultaneously detecting the larger system's twenty-four (24) VAC signal for the run mode or detecting the wireless communication device 34 for tuning the Taps. The motor controller microprocessor 22 may be capable of switching between the two demand sources, one demand source consists of the portable electronic device 24 through the wireless communication device 34, and the other demand source may be the larger system through the T1, T2, T3, T4, T5 tap inputs. Once the wireless communication device 24 is active, the motor's Taps can be changed based on previous history or based on measured parameters, such as data from one or more sensors (e.g., temperature or air flow sensors), or based on stored information in the system's controller or performance manual. This dual mode of operation and recognition by the motor controller microprocessor 22 is not limited to a motor with Tap selection.


There may be multiple methods for tuning the existing motor to new performance, and FIG. 7 concerns a process of “Band Tuning” and FIG. 8 concerns a process of “Combination Tuning.” Band Tuning involves selecting a desired increase or decrease in torque and moving all factory or previously set torques by a desired percentage of the current setting. The table 300 of FIG. 7 shows four possible final Taps setting of +/−five percent (5%) and +/−ten percent (10%). Combination Tuning allows for the tuning of Taps by selecting them in groups of two or more, wherein the group levels may be user selected from the portable electronic device. The table 400 of FIG. 8 shows several combination tunings of new Tap levels. FIG. 9 concerns an additional tuning feature which allows for selecting defined off delays to meet the larger system's requirements, whether that system is an HVAC unit in Heat or Cool mode or a fluid pump. The table 500 of FIG. 8 relates Tap selections to off delays. Tuning may also be achieved based on the larger system's power levels for any or all of the Tap inputs. The power levels might come from the larger system's stored information on the server 20 or from the motor 12 being replaced. The wireless communication device 34 in conjunction with running in the Tap mode allows for data from the larger system and motor performance history to be stored in the portable electronic device 24 and/or the server 20.


Referring again to FIG. 6, a service technician may establish a wireless connection between the portable electronic device 24 and the wireless communication device 32, as shown in block 604. The mobile motor servicing software application 30 on the portable electronic device 24 may display an indication that a wireless connection has been made. The wireless communication device 32 may transmit identification, programming, and/or operating information about the motor 12 such as a model number, HP rating, input voltage, manufacturer name, and other motor information to the portable electronic device 24 via the Bluetooth or other wireless connection, as shown in block 606, and the graphical user interface of the mobile motor servicing software application 30 may display the motor information on the display screen of the portable electronic device 24. Further, the larger system's demands may be recognized from signal inputs, as shown in block 608.


The mobile motor servicing software application 30 may evaluate the performance of the larger system, or may transmit the motor information to the server computer 20 to evaluate the performance of the larger system, and generate or receive from the server computer 20 motor tuning or other programming instructions, as shown in block 610. The mobile motor servicing software application 30 may transmit the tuning or other programming instruction (e.g., a new Tap level) to the motor controller 18, and the new programming instructions may be stored on and executed by the motor controller's microprocessor 22, as shown in block 612. The mobile motor servicing software application 30 may then re-evaluate the performance of the larger system to confirm improvement due to the new programming instructions, as shown in block 614. The technician may end the wireless connection, and the motor may continue to run with the new programming instructions, as shown in 616.


The above-described systems and methods for wirelessly tuning or otherwise reprogramming motors provide several advantages over conventional systems for reprogramming motors. For example, a technician can use their own or a readily available portable electronic device to reprogram the motor and does not need to take the motor to a location with a specialized motor reprogramming computer. Further, the technician does not need to have and carry programing tools, such as connectors for physically connecting to the motor. Further, the incorporated wireless communication devices facilitate interfacing with motor sensors whenever desired.


Although the invention has been described with reference to the one or more embodiments illustrated in the figures, it is understood that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the potential claims set forth below.
