STATOR, ELECTRIC MOTOR, AND MOTOR WITH SPEED REDUCER

摘要

PROBLEM TO BE SOLVED: To provide a stator, an electric motor equipped with the same, and a motor with a speed reducer, for suppressing vibration (operating sound) by resonance of a brush while improving rigidity.SOLUTION: A stator 50 has a bottomed cylindrical yoke part 8, and a cylindrical brush holder storage part 9 of a substantially ellipse cross-sectional shape integratedly provided in an opening side of the yoke part 8. A cylindrical ring magnet 10 is stored in the yoke part 8.
