Abstract
An electric motor and drive housing assembly includes a motor housing having an open end and a drive housing. The motor housing is affixed to the drive housing such that the opening of the motor housing faces the outer surface of the drive housing. A rotor accommodated in the motor housing has a rotor shaft supported in the motor housing and extending through the opening. A commutator is mounted on the rotor shaft in a region of the opening. A shaft bearing is mounted on the rotor shaft in a region of the opening. A brush carrier plate is attached to the motor housing and closes the opening. The brush carrier plate forms an end plate of the motor housing and a liquid-tight seal between the motor housing and the drive housing. Brushes are mounted on the brush carrier plate for cooperation with and shifting movement with respect to the commutator. Further, a centering arrangement is provided in the brush carrier plate for centering the shaft bearing.
