Patent ID: 8143753

Claim:
A motor stator comprising: a stator core including an annular yoke and teeth provided to at least one of an inside of the yoke and an outside of the yoke; an insulating cover which covers the stator core and includes at least one guide post; and three-phase windings wound on the stator core in a toroidal winding manner via the insulating cover, wherein each of a first phase, a second phase and a third phase includes a plurality of coils wound in the toroidal manner and a crossover wire connecting the coils, and wherein a crossover wire of at least one of the first phase, the second phase, and the third phase runs around the at least one guide post such that (i) an insulating space is formed between the crossover wire and a coil of another one of the first phase, the second phase, and the third phase and (ii) the crossover wire does not pass between the coil of the other one of the first phase, the second phase, and the third phase and the stator core.
