摘要： An electromagnetically variable transmission includes an outer rotor and an inner rotor. The inner rotor is independently rotatable within a center aperture of the outer rotor. The outer rotor is independently rotatable about the inner rotor. One of the rotors has a plurality of permanent magnets configured in pairs and facing an air gap disposed between the outer rotor and the inner rotor. The other rotor has a plurality of slots spaced about a magnetically permeable core having embedded windings. The outer inner rotors are simultaneously rotatable in one direction. In response to rotation of the outer rotor portion and the inner rotor portion, a magnetic flux path is generated between the permanent magnet pairs, the air gap, the outer rotor core and the inner rotor portion core, to induce electrical power in the windings, which transfers power between the inner rotor portion and the outer rotor portion.

摘要： A machine includes a rotatable rotor assembly having a number of salient poles. The machine further includes a stationary stator assembly having concentric inner and outer stators, at least one stationary superconducting field coil and at least one stator coil. The stationary superconducting field coil is disposed between the inner and outer stators and is mounted on at least one of the inner and outer stators. The stationary superconducting field coil and the salient poles are configured relative to each other, such that when the rotor assembly is rotated relative to the stator assembly around a predetermined axis, a rotating magnetic field is produced with an airgap flux direction substantially along the predetermined axis. The interaction between the stationary superconducting field coil and the rotating poles provides the only source of a time varying magnetic flux supplied to the stator coil.
