Claims

[Scope of utility model registration request]

A motor case is constructed by engaging two bottomed cylindrical frames formed by drawing a metal plate with flanges at the open ends of both frames, and a stator core is wound with a coil. a stator fitted and fixed in the motor case so as to straddle both frames, and a rotor core fixed to the rotating shaft, the rotor core being predetermined within the stator core. and a rotor whose rotating shaft is supported by a bearing mounted on a bearing mounting portion at the center of the end face of both frames, with an air gap disposed so that at least one of the frames has an air gap. A convex portion for equalizing the air gap between the stator core and rotor core is provided at a predetermined portion of the flange of one frame so as to protrude toward the flange side of the other frame. Characteristic motor.
