The invention relates to a circuit arrangement for operating an electric motor, in particular an electric motor for a windshield wiper. The electric motor has a first voltage connection, a ground connection, and a return connection. The ground connection is connected to a battery ground connection of a battery. Furthermore, a switch is provided, which is designed to open or disconnect a conductive connection between the ground connection and the return connection depending on an angle position of a shaft driven by the electric motor. Additionally, a filter member is arranged between the return connection and the ground connection.

Circuit arrangement for operating an electric motor

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

Electric drive

An electric drive, in particular a wiper drive for vehicles, is proposed, with an electric driving motor in a motor housing (), a brush holder () projecting into the motor housing (), an anti-interference module () which is connected electrically and mechanically to the brush holder () and is intended for the electrical connection and interference protection of the motor, and with a gear mechanism () which is attached to the motor housing (), at least partially accommodates the anti-interference module () and is designed in accordance with the predetermined position of the output shaft () with respect to the drive shaft (). 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 () and the brush holder () being equipped with corresponding retaining means () which permit the installation of a structurally identical anti-interference module () on the brush holder () in two installation positions rotated through 180&#xb0;.

An assembly device for an electronic component in sandwich type of construction. The electronic component includes at least one semiconductor element which is contacted in a planar fashion on its lower side and its upper side each by one circuit substrate. Using the assembly device, the two circuit substrates may be simply adjusted with respect to each other during assembly of the electronic component. For this, the assembly device includes a first lower shell including an accommodation for the first of the two circuit substrates, an arrangement for the defined alignment of the first circuit substrate in the accommodation, and a second, upper shell including an arrangement for adjusting the second circuit substrate positioned on the semiconductor element. A method for assembling an electronic component in sandwich type of construction, using such an assembly device, is also described.
