STATOR, BUS BAR UNIT, MOTOR, AND POWER STEERING DEVICE

摘要

A stator includes a core and a coil group. The core includes a ring portion, and a teeth portion preferably including twelve teeth portions projecting from an inside of the ring portion toward a center thereof. The coil group preferably includes twelve coils arranged in each of the teeth portions. The core is defined by coupling twelve cores which respectively include a teeth portion. The coil group preferably includes six coil pairs each including two coils joined to each other by a single conductive line. When the core is divided into a phase region and a neutral region equally along the axial direction, a first group of coils in each of the six coil pairs are arranged in the phase region, and the other coils are arranged in the neutral region.
