PROBLEM TO BE SOLVED: To provide an inexpensive stator supporting mechanism in a brushless motor by fixing a cap member and a stator core to a bearing housing firmly with good reliability in simplified structure, and doing away with the process of calking or bonding, and a method of manufacturing this supporting mechanism. SOLUTION: A bearing housing 1 is press-fitted in the mounting hole 2a of a stator base 2, and a mounting part 1a is fixed to the stator base 2 by calking or the like. Moreover, a circuit board 3 is mounted on the opposite side from the mounting part 1a of the bearing housing 1 of the stator base 2. Moreover, the center hole 5a of the stator core 5, which is received on the step 1b of the peripheral large-diameter part of the bearing housing 1 and on which a coil 4 is wound, fits on the peripheral middle diameter part 1c of the bearing housing 1. Moreover, a bearing 6 is press-fitted at the inside periphery 1d of the bearing 1 so as to bear a rotary shaft 7. A cap member 9 is attached into the opening 1e of the bearing 1 so as to catch an oil packing 8 and a stator core 5. COPYRIGHT: (C)2003,JPO |
