STATOR CORE FOR MOTOR

摘要

Provided is a stator core for a motor capable of facilitating an assembly work and parts management without increasing the number of components while suppressing leakage of magnetic flux passing through a flange to a coil. A stator core 13 has an annular yoke portion 15 and tooth portions 17 inwardly protruding from an inner periphery of the yoke portion 15 in a radial direction, wherein at a front end of the tooth portion 17 inwardly protruding in the radial direction, a flange portion 21 is provided so as to face a coil wound around the tooth portion 17 and wherein to the flange portion 21, a compressive residual stress portion M is provided.
