  • Patent number: 10122290
    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.

  • Patent number: 9274804
    Abstract: In accordance with at least some embodiments, a system includes a first processor and a second processor. The system also includes a boot task storage medium that can only be accessed by one processor at a time. A boot process of the system has a first stage and a second stage. During the first stage, the first processor fetches and executes boot tasks without assistance from the second processor. During the second stage, boot task execution performed by first processor overlaps with at least one boot task fetch performed by the second processor.

  • Publication number: 20140125155
    Abstract: Some embodiments of the disclosed invention provide a toroidal DC motor that reduces Back EMF and, therefore, minimizes the degradation of source potential. In addition, embodiments of the disclosed invention provide a motor that provides constant torque at constant current irrespective of the speed of the rotor. Likewise, some embodiments of the disclosed inventions provide output horsepower that increases with the rotational speed of the rotor.

  • Publication number: 20140028147
    Abstract: A Back Torque reducing electrodynamic generator machine is disclosed. Some embodiments include a multi-pole stator comprising field windings and power windings and a rotor having a flux path element. For some embodiments, the flux path element is attached to a rotor shaft at an oblique angle to the longitudinal axis of the shaft. The flux path element has a shape that provides a uniform constant air gap between it and the stator poles when the shaft is rotated.

  • Publication number: 20130187586
    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.

  • Patent number: 8476799
    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.

  • Patent number: 8373328
    Abstract: An electric motor with two or more stator sections, each possessing at least two salient pole projections having power windings, and two or more armature sections on a common shaft. The armature sections are at an angle to each other: e.g. 90 degrees for two armatures, 120 degrees for three armatures. Each armature has a lamination stack or ferrite core. The armature sections form a constant air gap with the field poles, and have an elliptical profile with respect to the output shaft. The armature sections have no electrical windings, or conductors and require no slip rings, rotor coils or permanent magnets. The power windings are energized by pulses of electric current. Said pulses are automatically supplied to the salient pole nearest the longest rotor flux path available, as determined by a shaft position sensor.
