ABSTRACT:
An electric drive, in particular a wiper drive for vehicles, is proposed, with an electric driving motor in a motor housing (50), a brush holder (10) projecting into the motor housing (50), an anti-interference module (18) which is connected electrically and mechanically to the brush holder (10) and is intended for the electrical connection and interference protection of the motor, and with a gear mechanism (52) which is attached to the motor housing (50), at least partially accommodates the anti-interference module (18) and is designed in accordance with the predetermined position of the output shaft (53) with respect to the drive shaft (58). According to the invention, the diversity of components of the electric drive and therefore, in particular, the diversity of tools for producing the components are reduced by the anti-interference module (18) and the brush holder (10) being equipped with corresponding retaining means (40, 44) which permit the installation of a structurally identical anti-interference module (18) on the brush holder (10) in two installation positions rotated through 180°.
