This disclosure relates to a system and method for operating a rotor effectively by applying an inductive load.
Magnetic converters, or, devices that produce usable electrical and/or mechanical energy through the use of magnetic fields, or flux, are well known in the art. Some examples of magnetic converters include electric motors, electric generators, transformers, etc. A typical magnetic converter includes at least a pair of permanent magnets and a wire coil free to rotate between the magnets. The magnets are generally connected by a steel former and the wire coil is connected to lead wires using brushes. In a magnetic converter that is used to generate usable mechanical energy, the wire coil may be further connected to a drive shaft.
In a magnetic converter that is used to generate mechanical energy, e.g., an electric motor, a voltage potential is applied across the lead wires, thereby causing an electric current to flow through the coil. The flow of the electric current induces a magnetic field, or flux, around the coil. The coil's magnetic field repels and attracts the magnetic field generated by the permanent magnets, which, in turn, causes the wire coil to rotate. Accordingly, usable rotational mechanical energy, or torque, may be drawn from the drive shaft.
In a magnetic converter that is used to generate electrical energy, e.g., an electric generator, the wire coil is rotated in a magnetic field generated by the permanent magnets, thereby inducing a voltage in the wire coil. Accordingly, when the lead wires are connected to a load, e.g., a light bulb, electric current may be drawn from the coil. Consequently, once current begins to flow through the rotating wire coil, a force opposing the motion of the wire coil is also induced, thereby making the wire coil harder to turn. Thus, as is explained by the conservation of energy law, the more work that the converter does, the more work that must be put into its operation. In physical practice, the work put into the operation of the converter is produced by applying a greater mechanical driving force, or increased input torque, to the rotating wire coil.
Accordingly, it would be desirable to provide a magnetic converter for generating electrical energy in which the input torque applied to the magnetic converter need not be increased to maintain operation of the converter. Further, it would be desirable to provide a magnetic converter for generating electrical energy in which an input torque is not required to maintain operation of the converter, and, hence, usable output torque may be drawn from the converter. Advantageously, in such a scheme, the magnetic converter may be used to generate usable electrical and mechanical energy, thereby increasing an efficiency of the magnetic converter.
In U.S. patent Ser. No. 11/381,703, inventor Steven Ward, Sr. teaches using one or more magnets oriented to create a counter-magnetic field for generating an electric current. According to Ward, a counter magnetic field is the magnetic field induced around a coil when a direction of a polarity of the wire coil's magnetic field is counter to a direction of a polarity of the magnetic field existent between one or more magnets. However in the prior art, a counter-magnetic field is applied to a coil outside the windings, and the windings are each on a separate core.
As such it would be useful to have a system and method for generating electric energy and torque using an improved magnet positioning to produce a counter-magnetic field.
This disclosure relates to a system and method for improvising motor efficiency using an improved magnet positioning and by applying an inductive load. A magnetic induction rotor assembly can comprise a core, a rotary device, a first winding, a second winding, and a magnet. The core can comprise a closed loop and two or more winding supports. The winding supports can be mounted to the inner portion of the closed loop. Each of the winding supports can comprise an orifice. The rotary device can comprise a rotor and a rod. The rod can pass between the winding supports. The first winding can be around a first side of one of the winding supports. The first winding can comprise a first plurality of turns. The second winding can be on a second side of the other winding supports. The second winding can comprise a second plurality of turns. The magnet can be mounted to the rod. The magnet can be within the orifices. The magnet can have a north pole and a south pole. The poles can be oriented such that an imaginary line can run from the north pole to the south pole is orthogonal to the rod.
This disclosure also teaches a method for generating electric energy. The method can comprise the steps of rotating a magnet within orifices of a first winding support of a core and a second winding support of the core, and generating a current in a first winding around the first winding support and a second winding around the second winding support. The magnet can have a north pole and a south pole. The poles can be oriented such that an imaginary line can run from the north pole to the south pole is orthogonal to the rod. The first winding support and the second winding support each connected to a closed loop of the core.
Described herein is a system and method for operating a rotor effectively by applying an inductive load. The following description is presented to enable any person skilled in the art to make and use the invention as claimed and is provided in the context of the particular examples discussed below, variations of which will be readily apparent to those skilled in the art. In the interest of clarity, not all features of an actual implementation are described in this specification. It will be appreciated that in the development of any such actual implementation (as in any development project), design decisions must be made to achieve the designers' specific goals (e.g., compliance with system- and business-related constraints), and that these goals will vary from one implementation to another. It will also be appreciated that such development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the field of the appropriate art having the benefit of this disclosure. Accordingly, the claims appended hereto are not intended to be limited by the disclosed embodiments, but are to be accorded their widest scope consistent with the principles and features disclosed herein.
In one embodiment, core 102 can comprise a soft iron made of laminated sheets, such as silicon steel. This can ensure that magnetization is not retained within core 102. Furthermore, core 102 can concentrate the strength and increase the effect of magnetic fields produced by electric currents and permanent magnets. Core 102 can comprise a metallic closed loop 106 and two winding supports 107a and 107b or more mounted to the inner portion of metallic closed loop 106. In one embodiment, winding supports 107a and 107b can be mounted opposite each other such that a first windings 104a and a second winding 104b can be parallel to each other. In a preferred embodiment, a gap will exist between winding supports 107a and 107b. Such gap can allow for multiple hysteresis loops. Rod 101b can pass between winding supports 107a and 107b. As such, windings 104 can form magnetic poles when energized with electrical current. Additionally, windings 104 can be electrically insulated from one another. In one embodiment, windings 104 can be balanced, or have the same number of turns. In another embodiment, windings 104 can be unbalanced, thus first windings 104a can have different number of turns than second windings 104b. Further each winding 104 can be connected to a load 105. Load 105 can refer to any component that uses electric energy to operate.
