MOLDED MOTOR

PROBLEM TO BE SOLVED: To provide a molded motor extending the service life of bearings. SOLUTION: A motor is composed of: a stator 4 formed by winding a driving coil 3 around a stator core 1 via an insulator 2; a printed circuit board 6 mounted with electronic components 5; a molded stator 8 formed by integrally molding the stator 4 and the printed circuit board 6 with resin 7; a magnetic rotor 9 rotatably held opposite to the stator core 1; a rotary shaft 10 passing through the center of the magnetic rotor 9; the bearings 11 which hold the rotary shaft 10; and a steel bracket 12 which is press-inserted into the molded stator 8 and holds the bearings 11. The motor is structured to form axial grooves 14 in the vicinity of a bearing holding part 13 integrally molded with the resin 7 on the side opposite the bracket 12. COPYRIGHT: (C)2010,JPO&INPIT
