Abstract
A curvilinear brush retainer and brushes for an electric motor assembly provides 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 along a curvilinear path. Brush liners are disposed within the curvilinear path maintained by the brush retainers, serving to reduce the stiction or frictional force imparted to the brushes as they move, thereby reducing the temperature of the brush and extending their operating life.
