    摘要: A rotating field transformer comprises a torque motor and a rotating electric machine having two sets of windings, each of the windings connected to a respective polyphase electric circuit. The two windings have the same number of magnetic poles and generate coincident rotating magnetic fields having the same direction of rotation. When a torque is applied (e.g., to the shaft of a rotor carrying one of the windings) in the same direction as that of the rotating magnetic fields, electric power is transferred from the rotor-connected circuit to the stator-connected circuit. The rotating field transformer can be used to control the frequency at which power is supplied to a polyphase load, or to manage instabilities in weak links between generating stations.

    摘要: A motor-generator set includes a rotatable central shaft and an AC rotor and a DC rotor being supported in tandem relationship along the shaft for rotation therewith. A liquid coolant flow path is defined in a series relationship through the shaft and rotors. A first portion of the serial liquid coolant flow path runs into and through a first single bore in one end portion of the shaft, a second portion of the serial flow path runs through the AC rotor, a third portion of the serial flow path runs through a middle portion of the shaft, a fourth portion of the serial path runs through the DC rotor, and a fifth portion of the serial flow path runs through and from an opposite end of the shaft. The middle and opposite end portions of the shaft, providing the third and fifth portions of the serial flow path, are formed by opposing end sections of a second single bore in the shaft and a plug disposed in a middle section of the second bore so as to substantially sealably isolate the opposing end sections from one another.

    摘要: The invention provides a high torque, high efficiency switched reluctance motor and method for generating electricity or mechanical energy with reduced CEMF resistance. The motor includes a rotor having a plurality of rotor poles, stators positioned around the rotor having a plurality of bifurcated stator poles, coil windings located in the separation between the legs of each stator pole, magnets mounted between adjacent stator poles, a shunt in electromagnetic communication with the coil windings and the stator poles, and a bridge component encircled by the coil windings and separating each stator pole from each shunt.

    摘要: An asynchronous converter comprises a torque motor and a rotating electric machine having two sets of windings, each of the windings connected to a respective polyphase electric circuit. The two windings have the same number of magnetic poles and generate coincident rotating magnetic fields having the same direction of rotation. When a torque is applied (e.g., to the shaft of a rotor carrying one of the windings) in the same direction as that of the rotating magnetic fields, electric power is transferred from the rotor-connected circuit to the stator-connected circuit. When the direction of the torque is reversed, the direction of the power transfer is also reversed. The two polyphase circuits may differ in voltage, in frequency and in number of electrical phases, but it is expected that in most cases the number of phases will be equal to three for both circuits and the operating frequencies of the two circuits will differ by no more than a few percent.
