Abstract
A motor includes a motor-base-holder which comprises (a) a base, (b) a bearing supporter vertically protruded from the base for supporting a bearing, (c) a stator supporter concentric with the bearing supporter for being mounted with a stator, (d) a motor base having terminals made of a metal plate and insert-molded around the bearing supporter, and (e) a frame made of the same metal as the terminals and linked to fringe of the motor base. This structure solves difficulties of mini-motors such as difficulties of handling the motor, difficulties of mating those elements each other, and time-consuming bonding action. A method of assembling the same motor achieves high productivity.
Claims3
A motor comprising:
- (a) a motor base including:
- (a-1) a base;
- (a-2) a bearing supporter protruded vertically from said base for supporting a bearing;
- (a-3) a stator supporter;
- (a-4) a plurality of terminals made of metal plate and disposed around said bearing supporter;
- (a-5) a metal tip extended outside of said motor base;
- (b) a stator mounted to said stator supporter;
- (c) a rotor supported by the bearing which is supported by said bearing supporter;
- and
- (d) a metal cover, of which end is fixed to said tip, for covering said rotor,
- wherein the base has a substantially flat side extending from at least one of said plurality of terminals to the metal tip.
