ELECTRICAL ROTATING MACHINE

摘要

Provided is a stator for an electrical rotating machine. The stator includes a stator core having a magnetic material. The stator core includes a cylindrical yoke extending in an axial direction of the stator. The yoke includes a plurality of yoke pieces having fracture surfaces disposed relative to each other along a circumferential direction of the yoke. The fracture surfaces of mutually adjacent yoke pieces of the plurality of yoke pieces have the fracture surfaces thereof in direct contact with each other. The stator core further includes a plurality of teeth extending in a radial direction from the yoke. Each of the teeth is provided on at least one of the plurality of yoke pieces. The stator further includes a stator coil wound around the teeth.
