Abstract:
1. A five-phase motor including A, B, C, D, and E phases, the five-phase motor comprising: a rotor with a number of poles; and a stator including: a stator core provided with a plurality of slots therein, and five pair of windings; the number of the poles of the rotor is an integer multiple of four; five slots in the plurality of slots are arranged within circumferential 360 electrical degrees of the stator; the five pairs of windings are arranged such that each of the windings is wound in two slots, the two slots being separated by two-slot pitches, and slots S 1 to S 12 in the plurality of slots are circumferentially arranged in order of the slots S 1 to S 12 , wherein the five-phase motor is configured such that: the five pairs of windings comprise a pair of a first a-phase winding and a second a-phase winding, a pair of a first b-phase winding and a second b-phase winding, a pair of a first c-phase winding and a second c-phase winding, a pair of a first d-phase winding and a second d-phase winding, and a pair of a first e-phase winding and a second e-phase winding; the first a-phase winding is wound in the slot S the first c-phase winding is wound in the C-phase slot S the first e-phase winding is wound in the E-phase slot S the first b-phase winding is wound in the B-phase slot S the first d-phase winding is wound in the D-phase slot S the second b-phase winding is wound in the slot S the second d-phase winding is wound in the D-phase slot S the second a-phase winding is wound in the A-phase slot S the second c-phase winding is wound in the C-phase slot S the second e-phase winding is wound in the E-phase slot S the slot S
