Patent ID: 8823232

Claim:
A rotary electric machine comprising: a stator including a stator core having an approximately loop-shaped core back portion and a plurality of main poles projecting radially inwardly from the core back portion, and windings arranged around the main poles of the stator core; a rotor arranged inside the stator with an air gap therebetween to be rotatable with respect to the stator; and a motor cover arranged to cover at least one of axial sides of the stator; wherein the motor cover is a metal plate including a loop-shaped outer frame arranged to be in contact at its edge with an end surface of the stator core from an axially outside location and a plurality of fixing pieces integrally provided with the outer frame and arranged to extend axially inward from the outer frame, each of the fixing pieces including a hole and a crimping portion provided on a close side of the hole to a distal end of the fixing piece; the stator core is provided with a concave portion arranged at a position corresponding to at least the crimping portion of the fixing piece; and the crimping portion is deformed such that it partially enters the concave portion of the stator core to thereby fix the motor cover to the stator core while the edge of the outer frame of the motor cover is in contact with the end surface of the stator core.
