Abstract
Detailed are brush assemblies for electric motors. The assemblies may include retention springs or other mechanisms designed to bias brushes away from surfaces of commutators during assembly of the motors. Such retention mechanisms additionally may be fitted into cavities in associated cover plates following motor assembly. The cover plates further may include tabs which, in use of the motor, assist in supporting side surfaces of the brushes and in orienting the plate relative to a corresponding brush card.
