Brush holder apparatus and system

A brush holder apparatus comprising:

• a stationary support member having at least one groove, the stationary support member having a fork electrical connector;
• a brush retainment member having a plunger brush restraint configured to restrain a brush from sliding within the brush retainment member by pressing the brush against the brush retainment member, the brush retainment member having at least one rail configured to slide along the at least one groove, the brush retainment member having a knife electrical connector configured to mate with the fork electrical connector;
• a pivoting bar connected to the plunger brush restraint, the pivoting bar connected to a pivot support and a spring that biases the plunger brush restraint against the brush, the pivoting bar is configured to follow a contoured surface of the stationary support member during insertion of the brush retainment member into the stationary support member;
• the brush is restrained against the brush retainment member during insertion of the brush retainment member into the stationary support member, and the brush is released when the brush retainment member is fully inserted into the stationary support member;
• a handle assembly comprising an electrically insulating handle having an electrically insulating guard configured to be located between the handle and brush connector leads, and a spring assembly mechanically connected to a brush terminal compression plate, the spring assembly configured to apply pressure to one or more brush terminals at least until the electrically insulating handle is in a locked position;
• and
• wherein the brush retainment member is configured to be releasably affixed to the stationary support member, and the stationary support member is configured for electrical connection to a collector mount and the brush retainment member is configured to retain the brush, and the brush retainment member is configured to clamp a brush terminal between a terminal compression plate and an opposing surface of the brush retainment member, and the brush terminal is engaged manually.
