DOUBLE STATOR PERMANENT MAGNET MACHINE

摘要

A double stator permanent magnet machine includes an inner stator having a back iron and a set of inner stator poles connected to the back iron, a rotor having a shaft and a set of segments, each segment having a permanent magnet, adjacent the inner stator and rotatively coupled to the inner stator, an outer stator having a set outer stator poles, adjacent the rotor and rotatively coupled to the rotor, a set of inner windings disposed between each of the inner stator poles, and a set of outer windings disposed between each of the outer stator poles.

1. A double stator permanent magnet machine comprises:
an inner stator, further comprising a back iron and a set of inner stator poles connected to the back iron; a rotor, further comprising an outer cage and a shaft connected to the outer cage, rotatively coupled to the inner stator; a set of segments, each segment further comprising a permanent magnet, connected to the outer cage; an outer stator, further comprising a set of outer stator poles, rotatively coupled to the rotor; a set of inner stator windings disposed between each of the inner stator poles; a set of outer stator windings disposed between each of the outer stator poles; a set of phases, each phase further comprising a subset of the set of inner stator windings and a subset of the set of outer stator windings; whereby the rotor rotates with respect to the inner stator and the outer stator, a reluctance torque is produced by the rotor and a reaction torque is produced by the rotor at a ratio of at least 1:3, when a current is selectively connected to the set of phases.
