Kind Code:
A1
Abstract:
Provided is a ring-shaped stator having as the center thereof a central axis extending vertically, the stator having a stator core that has a plurality of teeth aligned in the circumferential direction, and a plurality of coils formed by conductive lines being wound around each of the plurality of teeth. The plurality of coils have a three-phase coil group of a U phase, a V phase, and a W phase, and crossovers that function, respectively, as a relay between coils of the same phase. At the top side and bottom side of the stator core, the crossover for one phase is disposed in a region away from crossovers of other phases in the circumferential direction.
