摘要： A switched reluctance machine has a stator core salient with stator poles disposed concentrically with a rotor that is salient with rotor poles. A plurality of coil windings are wound about the stator core so that a pair of windings are adjacent each of the stator poles. The pair of coil windings induces magnetic flux in the adjacent stator poles and the rotor rotates to align the rotor poles with the stator poles having the induced magnetic flux. The rotor is rotatable at high speeds of up to 50,000 RPM and the coil windings can be directly cooled.

摘要： An electric motor comprising a stator and a rotor. The stator has at least one resonant circuit and the rotor has at least one resonant circuit rotatable with the rotor relative to at least one stator resonant circuit such that at least one rotor resonant circuit is angularly displaceable relative to at least one stator resonant circuit. At least one stator resonant circuit and at least one rotor resonant circuit are configured to have at least substantially the same self-resonant frequency. The electric motor uses magnetic resonant coupling between one or more stator resonant circuits and one or more rotor resonant circuits to produce usable torque.

摘要： A synchronous machine and related systems include a stator and rotor separated by an air gap. The rotor includes a rotating DC power supply coupled to exciter windings disposed adjacent the air gap. Power from air gap harmonics, including air gap slot harmonics induce current in the exciter windings, which is rectified and supplied to the rotor field windings. In operation, a desired current level in the rotor field windings can be achieved through control of the DC power supply or superposition of harmonics into the stator winding current which induces the prescribed current in exciter windings.

摘要： A hybrid excitation rotating electrical machine configured with a rotor having a shaft extended on at least one side in an axial direction, and first and second cores that are separated in the axial direction with a gap between the cores. First magnetic poles that are excited by a permanent magnet and second magnetic poles that are not excited by the permanent magnet are alternately arranged in a circumferential direction in each of the first and second cores. The first magnetic poles of the first core have a different polarity from that of the first magnetic poles of the second core, and the first magnetic poles of one of the first and second cores are placed so as to face the second magnetic poles of the other of the first and second cores in the axial direction with the gap between the magnetic poles.

摘要： A magnet-free rotating electric machine provided with an annular rotor between an outer and inner stators. The annular rotor includes pairs of inner and outer salient poles along a circumferential direction of an annular rotor yoke portion. Each rotor coil is diagonally wound between an inner circumferential surface of the rotor yoke portion on a first side and an outer circumferential surface of the rotor yoke portion on a second side with the pair of inner and outer salient poles sandwiched therebetween. A rectifying device ensures that the magnetic polarities of the inner and outer salient poles magnetized by the current of the rotor coil induced by the excitation of the outer stator and the inner stator are opposite to each other and further that the NS magnetic pole directions of the adjacent pairs of inner and outer salient poles are opposite to each other.

摘要： A magnetless rotating electric machine has an outer stator, an inner stator, and an annular rotor interposed between the outer stator and the inner stator. A plurality of outer-inner salient pole pairs are provided in the annular rotor along a circumferential direction of an annular rotor yoke. A rotor yoke coil is wound around one side of the rotor yoke and around another side of the rotor yoke along the circumferential direction with the respective outer-inner salient pole pairs sandwiched therebetween. Rectifying elements make a magnetic pole polarity of the outer salient poles and magnetic pole polarity of the inner salient poles, which are magnetized by an induced current of the rotor yoke coil caused by magnetization of the outer stator and the inner stator, identical with each other, and also make magnetic pole polarities of the adjacent outer-inner salient pole pairs opposite each other.

Each exciter unit comprises two secondary magnetic circuits and one primary magnetic circuit. Each secondary magnetic circuit comprises a stator exciter winding and two annular yokes provided with teeth. The primary magnetic circuit comprises a rotor exciter winding and an annular ring. First magnetic fluxes generated by the primary magnetic circuit circulate around loops in each strip and second magnetic fluxes generated by the secondary magnetic circuits circulate around loops in the strips, the teeth, and the ring. Each strip thus has a first north pole and a first south pole, with the teeth comprising in alternation second north poles and second south poles.
