Dynamoelectric machine brush rigging

摘要

An end cap assembly for a direct current motor. The assembly includes a brush retainer supported by the end cap that engages spring biased brushes to maintain the brushes in a retracted position. When an armature shaft is assembled to the end cap a portion thereof engages the retainer to move it relative to the end cap to a position where the brushes now engage the commutator of the armature. The retainer becomes a part of the motor. The end cap is formed as a one-piece plastic part that carries metallic brush holders and a circuit breaker. The circuit breaker is connected to one of the brush holders and to a terminal by C-shaped clips.
