Abstract
A curvilinear brush retainer and brushes for an electric motor assembly comprises an end plate upon which is disposed a pair of curvilinear brush retainers. The brush retainers are configured to retain and support a pair of curvilinear brushes as they are biased against the commutator of the electric motor. The curvilinear profile or shape of the brushes allows them to have an extended physical length, thereby allowing the electric motor to have an extended operational life.
