Electric motor and electric drive unit for motor vehicles

Abstract

The invention relates to an electric motor for motor vehicles, in particular a direct current low-power electric motor, comprising a housing (3) and a brush assembly holder (7) which holds at least two brush holders (21) with brushes (22) attached thereto, such that the brushes (22) are in biased contact with commutator (23), wherein the brushes (22) are pre-ground corresponding to commutator (23). According to the invention, the brush assembly holder (7) is movably supported in relation to the commutator (23) and a limit stop (13) fixed relative to the housing is provided in order to position the brushes (22) accurately on the commutator. Consequently, further production tolerances, for example when pushing the plug-in electronic module into the housing of the electric motor, have no effect on the accuracy with which the brushes are positioned. The invention further relates to an electric drive unit for motor vehicles, in particular for window lifts or designed as an electric actuator unit, comprising the electric motor referred to above.
