Abstract: Apparatus and associated methods relate to a switching network that (1) receives energy from an input source that magnetically excites an output winding, (2) stores some of that energy in a series capacitance while delivering power to a resistive load during a first excitation cycle portion, and (3) then injects some of the stored energy back to the input source by injecting current into a tap of the output winding while delivering power to the resistive load and during a second excitation cycle portion. In an illustrative example, the first excitation cycle portion may include a first positive or negative quarter cycle of the excitation waveform. The second excitation cycle portion may include a second positive or negative quarter cycle of the excitation waveform. The energy injected back to the input source during the second excitation cycle portion may advantageously provide, for example, an assisting torque to a prime mover.

Abstract: A Back EMF reducing DC motor system and method of operation are disclosed. The disclosed system and method are designed to exploit Transformer Voltage properties and include a rotor element shaped to periodically move a flux zone along a stator face. Incoming DC motor power from an external source may be appropriately conditioned and applied to a power supply, Storage Capacitors may also communicate with the power supply. A controller receives power from the power supply and communicates with the DC motor. A position sensor or other indicator may also communicate DC motor operational conditions to the controller. A recapture storage device may receive recaptured power from the DC motor via the controller. The recaptured power may he used to power an external load, or to reduce the input power necessary to operate the DC motor.

Abstract: Embodiments of controllers for electric motors, and methods of operation for the same are disclosed. More particularly, the controllers and methods of operation are for motors designed to operate so as to reduce Back EMF.

Abstract: A synchronous reluctance motor system is disclosed. The system may generally comprise an input power source that provides alternating phase current and voltage (e.g., AC current). The input power may be further conditioned through a variable voltage conditioner. The system may also include capacitive elements connected in series with the motor windings.

Abstract: Electric motor cluster consisting of several stator sections each possessing a minimum of two salient pole projections, wound with power windings, and each section containing a single rotor. Each individual motor is angularly displaced one from the other, while mounted within a common housing, and geared together such that each motor section contributes to the rotation of a common output shaft. Each motor comprises at least one stator and one rotor section, such that each rotor section is associated with a specific stator section. The lateral axis of each rotor section is disposed at an oblique angle with respect to the axis of the shaft for that particular motor.

Abstract: An alternator having a rotor which extends obliquely with respect to its axis of rotation between at least a pair of pole pieces having power windings disposed therein with the turns of the windings facing the pivotal axis of the rotor. Upon driving the rotor in rotation, the rotor due to its oblique configuration causes the flux extending with respect to the pole pieces to reciprocate with respect to the pivotal axis and the power windings, thereby producing two cycles of alternating current for each rotation of the rotor. The form of the rotor can substantially correspond to a portion of a cylinder having oppositely disposed face portions extending obliquely with respect to the central axis of the of the cylinder which is substantially coincident with the pivotal axis of the rotor. The periphery of the rotor thereby generates a cylindrical figure of revolution as the rotor is rotated.
