ELECTRIC MOTOR

PROBLEM TO BE SOLVED: To provide a motor reducing the manufacturing cost by keeping smooth sliding movement between the bearing and the bearing housing of a motor and preventing defects of the bearing and reducing the manufacturing cost by reducing the machining mandays, the assembling mandays, the number of parts. SOLUTION: In a motor provided with a stator 9 formed of lamitated cores, a rotor 8 formed of lamitated cores, a rotary shaft 1 on which the rotor 8 is firmly fitted to the outer periphery thereof, the bearing housings 3, 10 attached to both ends of the stator 9 by projecting the front end and the rear end of the rotary shaft 1, and the bearings 2 internally fitted into the bearing housings 3, 10 respectively so as to rotatably support the rotary shaft 1, the bearing housing 3 is provided with one recession 3b formed in the vicinity of the center of the inner diametral face of the housing and a support part 3a installed to support the rotary shaft 1 at both sides of the recession 3b. In this way, the bearing 2 slides smoothly and inconveniences such as seizure of the bearing 2 or the like brought by an excessive load applied on the bearing 2 can be prevented.
