Cross reference is made to the following application: 14-FW-007-UPA1 titled “CONTROLLER, MOTOR ASSEMBLY AND ASSOCIATED METHOD” filed concurrently herewith which is incorporated herein by reference.
The embodiments described herein relate generally to fluid moving devices and controller, and more specifically, to a pump motor controller.
Pool and spa pumps are used to circulate water within the pool. The circulation of the water disperses chemicals added to the water to provide for acceptable water conditions. The circulation also permits the passage of water through a filter to remove impurities from the water. Typically the pump operates for a portion of the week, typically on a schedule. The pump is typically powered by an electrical motor. The motor may be manually operated, wherein the operator manually controls the pump weekly cycle by manually turning the pump motor off and on.
More sophisticated pool pump systems have timers for turning the pump off and on based on a schedule. Some even more sophisticated pool pump systems have electronic controllers located in or adjacent the pool pump motors or within a pool system. These electronic controllers regulate the operation of the pool pump. These electronic controllers determine the on and off times of the pool pump motor. They may also control the speed of the pump if the pool pump motor has more than one possible speed.
These pool pump systems may not provide for optimum pool conditions either at set up or over time when pool conditions change. These systems
require periodic adjustments to the scheduled on off times and to the motor speeds to obtain optimum efficiency. Such systems may not provide for optimum pool conditions at initial set up and may not provide for optimum pool conditions when adjustments are made to respond to changing pool conditions. Typically such pool pump motor scheduling is made with a trial and error approach.
The present invention is directed to alleviate at least some of these problems with the prior art.

Pool and spa pumps are used to circulate water within the pool. The circulation of the water disperses chemicals added to the water to provide for acceptable water conditions. The circulation also permits the passage of water through a filter to remove impurities from the water, to aerate the water, and to provide uniform water temperature in the pool. Typically the pump operates for a portion of the week, typically on a schedule. The pump is typically powered by an electrical motor. The motor may be manually operated, wherein the operator manually controls the pump weekly cycle by manually turning the pump motor off and on.
The electrical motor typically includes a housing for containing and supporting a stator which is excited by an electrical source that excites an electromagnetic field in coils in the stator. The coils interact with a rotor rotatably supported in the housing to provide the mechanical rotational energy for the electrical machine.
Many modern electric machines include a control, for controlling the motor. The control may control the speed and direction of the motor by, for example, controlling the electrical energy going to the coils. The control typically includes a plurality of electrical components.
The electric machine typically includes a housing for containing and supporting the stator. While the electrical components may be positioned in a separate control, spaced from the housing of the electric machine, typically, to reduce cost, to reduce space requirements or for other reasons, at least a portion of the electrical components are positioned within the electric machine housing.

According to an embodiment of the present invention and referring to
The electric motor 12 typically includes a centrally located motor shaft 14 that rotates relative to the motor 12. Electrical energy is applied to coils 15 within the motor 12. The coils 15 generate an electromagnetic field that cooperates with an electromagnetic field in rotor 13 mounted to the motor shaft 14. The coils 15 initiate relative motion between the shaft 14 and the motor 12 that transfers the power from the coils 15 to the shaft 14.
A stationary assembly 16, also referred to as a stator, includes stator core 11 and coils 15 or windings positioned around portions of the stator core. It is these coils to which energy is applied to initiate this relative motion which transfers the power to the shaft. These coils 15 are formed by winding wire (not shown), typically copper, aluminum or a combination thereof, about a central core to form the winding or coil. An electric current is directed through the coils 15 which induces a magnetic field. It is the magnetic field that initiates this relative motion which transfers the power to the shaft 14. The stator core 11 typically includes a plurality of stator core laminations 19 that define stator teeth (not shown) around which the coils 15 are wound.
Typically the motor 12 includes a housing 17 having an inner wall or surface that defines a motor cavity therein. The housing 17 may include a plurality of components and may be made of a suitable durable material, for example a metal, a polymer or a composite. The housing 17 may, as shown, include a cylindrical shell 18 and opposed end caps (not shown).
It should be appreciated that the housing of the motor may have any suitable shape. One common shape of a motor housing is that of a cylindrical solid, having a generally cylindrical cross section. The shaft on a motor with such a shape generally extends from an end of the motor.
The motor 12 may have any suitable size and shape and may be, for example, an induction motor, a permanent-split capacitor (PSC) motor, an electronically commutated motor (ECM) motor, or a switched reluctance motor. The motor 12 may, as shown, be a radial flux motor or may be an axial flux motor. The housing 17 may include protrusions, for example fins (not shown), for dissipation of heat. The motor 12 may also include a fan (not shown) positioned within housing 17. The motor 12 may be electronically controlled, particularly if the motor is an ECM motor, by, for example a motor controller 20. The motor controller 20 may be internally or externally mounted to the motor 12. Alternatively, the controller 20 may be spaced from the motor 12 and may, for example be a part of a system controller (not shown).
According to an embodiment of the invention and referring now to
For example and as shown in
The pump motor controller 20 may be any suitable controller capable of controlling the motor and capable of receiving signals to so control the motor 12. The controller 20 may include a circuit board or boards (not shown) that are adapted to receive electronic components (not shown), in the form of, for example, discrete components, integrated circuits or some combination thereof.
The pump motor controller 20 may, for example, include a timer 28 which may be used to determine the run time(s) of the pump motor 12. The timer 28 may be integral with the controller 20 or may be a separate component. The timer 28 and/or the controller 20 may send a run time signal 30 or multiple signals through, for example, a run time electrical conduit 32. Alternatively the timer 28 may be positioned between power source 34 and the controller 20 and the timer 28 may be used to permit power to the controller when the time(s) selected for the pump to operate occur(s).
As shown in
The pool parameters 38 may, for example, include pool size, plumbing size, plumbing length, number of skimmers, and number of drains. Pool size may, for example, include the dimensions of the pool, the pool shape, the number of cubic feet of water or the number of gallons of water. The plumbing size may, for example, include the diameter of the pipes. The plumbing length may, for example, include the number of pipe sections and the length of those sections.
The pump parameters 40 may, for example, include impeller specifics, pump manufacturer, pump flow rate, pump speeds and pump horsepower.
The user preferences 42 may, for example, include desired turnovers and desired operation method. The desired operation method may be a method based on being one of the cleanest method, the lowest cost method, the quietest method and the highest flow method.
Referring again to
The pump motor controller 20 may be configured to turn the other pool devices 44 off and on based at least in part on one of data 36 in the form of one of pool parameters 38, pump parameters 40 and user preferences 42.
The pump motor controller 20 may be adapted to adjust motor speed of the motor 12 to achieve a maximum efficiency while reaching and maintaining desired pool parameters, pump parameters and user preferences.
While only one of pool parameters 38, pump parameters 40 and user preferences 42 may be needed to determine the speeds and run times of pump motor 12, more than one of pool parameters 38, pump parameters 40 and user preferences 42 may be used. For example, pool parameters 38 and user preferences 42, pool parameters 38 and pump parameters 40, or pump parameters 40 and user preferences 42 may be used. Alternatively, all three of pool parameters 38, pump parameters 40 and user preferences 42 may be used. Alternatively and/or in addition, the speeds may be dependent on the durations and the durations may be dependent on the speeds.
The determination of the speeds and run times of the pump motor 12 may be performed by the pump motor controller 20 or a similar controller such as a pool system controller. The determination of the speeds and run times may be determined by providing or utilizing code for the controller. The determination of the speeds and run times may be based on formulas and or by the use of tables which provide pump speeds and run times based on inputs to the controller of pool parameters, pump parameters and/or user preferences. Expressed in mathematical terms:
Speed 1=fn(popn,pupm,upp,dur1)n=1, . . . , N; m=1, . . . , M; p=1, . . . , P
Speed 2=fn(popn,pupm,upp,dur2)n=1, . . . , N; m=1, . . . , M; p=1, . . . , P
Speed 3=fn(popn,pupm,upp,dur3)n=1, . . . , N; m=1, . . . , M; p=1, . . . , P
Duration 1=fn(popn,pupm,upp,spe1)n=1, . . . , N; m=1, . . . , M; p=1, . . . , P
Duration 2=fn(popn,pupm,upp,spe2)n=1, . . . , N; m=1, . . . , M; p=1, . . . , P
Duration 3=fn(popn,pupm,upp,spe3)n=1, . . . , N; m=1, . . . , M; p=1, . . . , P
Where: pop=pool parameters
These above equations can be determined based on empirical data obtained by varying one or more variables and plotting the results.
Note that the equation above assumes that the function is only dependent on the corresponding speed or duration. Alternatively, the equation may be dependent on additional speeds and durations.
