Abstract:
1. A motor comprising: a stator core; a rotor comprising a plurality of magnets and an integral rotation shaft; an output side bearing that engages and rotationally supports an output side of the rotation shaft; a cylindrical motor case having a bottom that supports an outer circumferential surface of the stator core by an inner circumferential surface thereof; and a bracket that directly supports the output side bearing and closes an opening of the motor case; an end housing that press-fits into the cylindrical motor case, the end housing including a through hole that directly supports another bearing at a side of the rotor opposite the output side bearing; and a cover that overlaps the bottom of the motor case and that covers the end housing, wherein the stator core includes a first portion that press-fits into the motor case from the opening and a second portion that extends from the first portion beyond an end of the motor case, the second portion including a sliding fitting connection with the bracket to align a center of the bracket to a center of the rotation shaft based on the stator core, and wherein the motor is a brushless motor.
