Abstract
A commutator motor brush mounting arrangement is arranged in an axial opening of an electric motor housing. The arrangement is provided with mounting bars which protrude axially from a support plate, the mounting bars being arranged at the interior of the motor housing. Hammer-shaped brush holders which are formed with half-open bearing shells are rotatably engaged with the mounting bars. Axial displacement of the brush holders in a first direction is prevented by the front plate, and in a second direction by an end plate. The end plate is provided with elastic openings for engaging posts arranged on the mounting bars in a self-locking manner. The support plate and the end plate are provided with respective complementary guide portions in the form of support ribs and corresponding depressions. Such guide portions rotatably secure the hammer-shaped brush holders to the mounting bars, so as to prevent canting and binding of the brush holders within the motor housing.
