Switched reluctance motor

摘要

Disclosed herein is a switched reluctance motor having a double rotor structure. An outer stator salient pole corresponding to an outer rotor salient pole is formed to have an “E” shape by sequentially disposing a main salient pole, a first auxiliary salient pole, and a second auxiliary salient pole and an inner stator salient pole corresponding to an inner rotor salient pole is formed to have a pi (π) shape by sequentially disposing a first salient pole and a second salient pole, such that a magnetic flux path is reduced, thereby making it possible to prevent the loss of magnetic force.

1. A switched reluctance motor comprising:
an outer rotor including a plurality of outer rotor salient poles formed at equidistance along a circular inner circumferential surface thereof; an inner rotor received in an inner portion of the outer rotor and including a plurality of inner rotor salient poles formed at equidistance along a circular outer circumferential surface thereof; and a stator core formed between the outer rotor and the inner rotor and including a plurality of outer stator salient poles each including a main salient pole, a first auxiliary salient pole, and a second auxiliary salient pole that correspond to the outer rotor salient poles and are sequentially formed along an outer circumferential surface thereof and a plurality of inner stator salient poles each including a first salient pole and a second salient pole that correspond to the inner rotor salient poles and are sequentially formed along an inner circumferential surface thereof, wherein each of coils is wound around the main salient pole and the first and second salient poles.
