摘要:
A brush board assembly for a DC or AC motor employs a spool-shaped frame unitarily formed of a mounting plate, a series of support members that extend axially and define the brush holders, and an outer support plate that is generally parallel to the mounting plate. This frame may be molded of a high strength, high temperature resin for heavy duty motor use. Brush hold down springs are mounted onto push-in carriers that fit into receptacles on the support members. Preferably, scroll or volute springs are employed, and a stop arm on the carrier allows the free end of the spring to be held out of the way for installation or brush change out.
