  • Method of machining motor frame body and motor machined by the method
    Patent number: 5894653
    Abstract: A stator (76), a rotor (82), and frame bodies (84, 86) to fixedly hold a stator core (74) therebetween in an axial direction are assembled into a motor. Further, a shaft (78) of the rotor and the frame body (86) are mutually coupled through a coupler (106) with no ability for relative rotation. While integrally rotating the frame bodies (84, 86), the stator (76), and the rotor (82) forming the motor about an axis of the rotor (82), a lathe is used to machine mounting surfaces (96a, 100a) of the frame body (84), which will be in direct contact with a surface of an object on which the motor is mounted.
