<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing motor, capable of preventing the brush slide-contact portion side in a rectifier piece from floating outward in the peripheral direction of an insulator. <P>SOLUTION: This method of manufacturing motor includes a "winding connection process" for electrically connecting a winding 4a to a rectifier 3 which is formed by disposing the plurality of rectifier pieces 8 in the circumferential direction on the outer peripheral side of the cylindrical insulator 7. In the rectifier pieces 8, a brush slide-contact portion 8a with which the brush is brought into slide contact on one side in the axial direction is formed; a claw portion 8b, which is engaged with the winding 4a, is formed on the other side in the axial direction; and a bending fulcrum portion 8d where the claw portion 8b is bent inward in the radial direction when pressed, is formed closer to the claw portion 8b side than the brush slide-contact portion 8a (located between the brush slide-contact portion 8a and a thin portion 8c). Additionally, the "winding connection process" performs welding, while pressing the claw portion 8b engaged with the winding 4a, inward in the radial direction with an electrode D for welding, thus bending the bending fulcrum portion 8d by the pressing force of the electrode D for welding. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
