  • Patent number: 8026645
    Abstract: The invention relates to an electric drive, particularly a windshield wiper drive for vehicles, comprising an electric motor (10) in a crucible-shaped, preferably metal, motor housing (14), a gearbox housing (16) that is attached to the motor housing (14), and an arrangement for the interference suppression of the motor (10). According to the invention, at least one choke coil (46, 48) for the interference suppression of the motor (10) is disposed in the transition region from the motor housing (14) to the gearbox housing (16), wherein in this transition region means (36, 56) are provided in order to shield the filtered coil end (47, 49) projecting into the gearbox housing (16) from the interfering radiation produced by the motor (10).

  • Publication number: 20080238227
    Abstract: The present invention relates to a sliding-contact holder (8) for an electric motor, which has a cylindrical motor housing (1), a front housing cover (2), a rear housing base (3), a rotor shaft (4), a rotor (5), a commutator (6), a stator (7) and a sliding-contact holder (8). The sliding-contact holder (8) comprises at least two holder elements, which each bear at least one sliding contact (11). The two holder elements are inserted individually into the cylindrical motor housing (1). Owing to its design, the sliding-contact holder (8) saves on space and can easily be inserted into the motor housing (1).
