摘要： A hybrid induction motor includes a fixed stator, an independently rotating outer rotor, and an inner rotor fixed to a motor shaft. The outer rotor is designed to have a low moment of inertia and includes angularly spaced apart first bars and permanent magnets on an inner surface of the outer rotor. The inner rotor includes angularly spaced apart second bars and interior flux barriers aligned with the second bars. The outer rotor is initially accelerated by cooperation of a rotating stator magnetic field with the first bars. As the outer rotor accelerates towards synchronous RPM, a rotating magnetic field of the permanent magnets cooperate with the second bars of the inner rotor to accelerate the inner rotor. At near synchronous speed the rotating stator magnetic field reaches through the outer rotor and into the inner rotor coupling the two rotors for efficient permanent magnet operation.

摘要： An induction machine with integrated magnetic gears is disclosed. The machine comprises two rotors and two stators. An outer stator has ferromagnetic material, producing a rotating magnetic field with a defined number of pole pairs synchronized with a supply frequency. A high speed rotor has ferromagnetic material and a combination of rotor bars and permanent magnet pole pieces selected so that the permanent magnet pole pieces do not interact with the outer stator magnetic field. The high speed rotor rotation is asynchronously coupled to the outer stator magnetic field. An inner stator has ferromagnetic steel segments that modulate the field produced by the high speed rotor permanent magnets. A low speed inner rotor has ferromagnetic material and permanent magnet pole pieces, the low speed inner rotor counter-rotating to the high speed rotor. The low speed inner rotor is synchronously coupled to the high speed rotor using modulation harmonics.

摘要： A synchronous reluctance type rotary electric machine of an embodiment includes a shaft, a rotor core, rotor core pressers, a plurality of conductor bars, and short-circuit rings. The shaft rotates around a rotation axis. The rotor core is fixed to the shaft and includes multi-layered hollow parts having a convex shape toward a radially inward side formed for each pole in cross section. The rotor core pressers hold the rotor core by pressing the rotor core from both sides in a rotation axis direction. The plurality of conductor bars are disposed in the hollow parts to extend along the rotation axis and have both ends protruding through the rotor core pressers. The short-circuit rings are provided at both ends of each of the plurality of conductor bars and connect the plurality of conductor bars together. Thus, the conductor bars are fixed to the rotor core pressers.

摘要： A hybrid induction motor includes a fixed stator, an independently rotating outer rotor, and an inner rotor fixed to a motor shaft. In one embodiment the outer rotor includes spaced apart first bars and permanent magnets, and the inner rotor includes spaced apart second bars. In another embodiment the outer rotor includes angularly spaced apart first bars but no permanent magnets, and the inner rotor includes permanent magnets and may also include angularly spaced apart second bars. The outer rotor is initially accelerated by cooperation of a rotating stator magnetic field with the first bars. As the outer rotor accelerates towards synchronous RPM, the inner rotor is accelerated to transition to efficient synchronous operation. The outer rotor thus acts as a clutch to decouple the inner rotor from the rotating stator magnetic field at startup and to couple the inner rotor to the rotating stator magnetic field at synchronous speed.

摘要： A hybrid induction motor includes an inductive rotor and an independently rotating permanent magnet rotor. The inductive rotor is a squirrel cage type rotor for induction motor operation at startup. The permanent magnet rotor is axially displaced and variably coupled to the inductive rotor (or to a motor load) through a clutch and is allowed to rotate independently of the inductive rotor at startup. The independently rotating permanent magnet rotor quickly reaches synchronous RPM at startup. As the inductive rotor approaches or reaches synchronous RPM, the coupling between the inductive rotor and the permanent magnet rotor increases until the two rotors are coupled the synchronous RPM and the motor transitions to efficient synchronous operation.
