摘要： A magnetic transmission is provided with: an inner rotor; an outer rotor; and a magnetic-field-modulating stator disposed coaxially between the inner rotor and the outer rotor. The inner rotor is provided with a first magnet array and a second magnet array arranged in the direction of the central axis and disposed at different pitches along the circumferential direction. The outer rotor is provided with a magnet array disposed along the circumferential direction. The magnetic-field-modulating stator is provided with a first magnetic body array and a second magnetic body array opposing the first magnet array and the second magnet array, respectively. Further, by moving the inner rotor and the magnetic-field-modulating stator in the direction of the central axis while holding the opposing relationship between the first magnetic body array and the second magnetic body array, and the first magnet array and the second magnet array, the position where the outer rotor, and the first magnet array and the second magnet array oppose each other is changed continuously.

摘要： A permanent magnet motor/generator that includes a stator, a rotor provided with a plurality of permanent magnets at a peripheral surface thereof and having a central axis which coincides with the central axis of the stator, a rotatable shaft upon which the rotor is coupled, and an actuator for moving the rotor with respect to the stator axially along the rotatable shaft a sufficient distance to completely decouple the rotor from the stator so as to eliminate magnet induced torque drag. When the permanent magnet/generator is used in parallel hybrid vehicles, the ability to completely decouple the rotor from the stator greatly improves range and efficiency. In addition, by progressively engaging the rotor with the stator a desired voltage output can be obtained upon deceleration.
