摘要： A rotating field machine (200) including a stator (140) and a rotor (150) are provided. In particular, a dual-winding rotating field machine (200) in which the stator (140) includes two separate windings can be provided. In one example implementation, the stator (140) can include an excitation winding (220) configured to control an excitation current and a power winding (230) configured to control power flow to an electrical system. The dual-winding rotating field machine (200) can further include a starting mode and a generating mode. During the starting mode, both the excitation winding (220) and the power winding (230) can be coupled to one or more switching power converters (170). During the generating mode, the power winding (230) can be coupled to a variable frequency bus and the power converter (170) can be used to manage excitation power only.

摘要： A power supply device for an internal combustion engine, using a generator driven by an internal combustion engine as a power source and supplying power to a first load that needs to be constantly driven to cause the internal combustion engine to operate and a second load that is permitted not to drive during startup of the engine, characterized in that a first generation coil for driving the first load and a second generation coil for driving the second load are provided to be magnetically-coupled tightly in the generator, and voltage supplied to a load is boosted to a higher voltage value than conventionally achieved by performing chopper control of an energizing current of the first generation coil and an energizing current of the second generation coil while preventing energization from the second generation coil to a load.

摘要： Provided are a field control method and a rotating electric machine of good energy efficiency in a magnetic-excited rotating electric machine. In the magnet-exciting rotating electric machine system of this invention, a rotor surface has magnetic salient poles and island-shaped salient poles alternately in circumferential direction, and the island-shaped salient poles are constituted so that magnetic flux coming from an external source may not be hard to pass through. A magnetic excitation part magnetizes the island-shaped salient poles and the magnetic salient poles collectively in the same direction, and then control amount of magnetic flux crossing armature coils. The armature coil has armature coils that face the magnetic salient poles and the island-shaped salient poles simultaneously so that torque variations and power generation voltage waveform distortion are inhibited. The magnetic excitation part is configured to change magnetization state of a field magnet irreversibly, and to change the amount of magnetic flux supplied by an excitation current, and a rotating electric machine system that enables low current and large torque, high-speed rotation is realized.

摘要： A dynamo-electric machine is so constituted as to easily change the characteristics of a dynamo-electric machine comprising permanent magnets and comprises a field control coil so as to adopt the dynamo-electric machine comprising common components to various applications. In this dynamo-electric machine, the field control coil is so adopted to a field which a magnetic pole and an iron pole supply to core teeth so as to superpose magnetic fluxes of different strengths. A permanent magnet is disposed in a recess of the inner peripheral face of a yoke to form a magnetic pole by a permanent magnet, and an iron pole by a yoke section between adjacent permanent magnets, and the inner peripheral face of the permanent magnet is located below the yoke section, thereby differentiating the strengths of magnetic fluxes.
