摘要:
A brush assembly 22 for an electric motor 10 has brush holder 24 supporting a brush 26 and a brush spring. The brush holder 24 has a strip of brass having a central portion and two end portions 28, 40. The central portion has two pins 30 extending in a parallel fashion away from the central portion. A brush 26 has two grooves 64 which mate with and accommodate the pins 30 whereby the pins 30 support the brush 26 and prevent movement of the brush 26 except in the direction along the pins 20. The brush spring is a coil spring mounted on a post 54 formed at one end of the strip by a transverse slot 52 and bears on the back side of the brush 26 to urge it to slide along the pins away from the brush holder 24.
