The invention relates to an electrical machine (), in particular an electric motor, suitable for the adjustment by external force of elements of a motor vehicle, essentially for driving a steering booster. The inventive electrical machine comprises a rotor () and a shaft (), the rotor having a plurality of plates (), wherein the plates () are premounted on the shaft either individually or as a plate assembly () or by means of a plurality of plate assemblies (), the rotor () being connected to the shaft (). The plates () have resilient lugs () for fixing the plates () and/or plate assemblies () to the shaft (). Furthermore, the plates () of the plate assemblies () comprise centering lugs () which serve to radially center the plate assembly () relative to the shaft (). An attachment of the stator () in a housing part () is possible, wherein centering lugs () at the plates () of the plate assembly () of the stator () serve to center the plate assembly () of the stator () relative to the shaft ().

Electrical machine

The invention relates to a DC current machine, in particular a DC current motor for driving a blower of a motor vehicle, with a pole housing forming the stator of the machine, a rotor that is rotatably mounted in two bearing plates, and with a brush support for supplying current to the rotor. According to the invention, a support is integrated into the brush support, with de-tensioning for the electrical connecting cables of the machine, which means that a secure fastening, de-tensioning, and insulation of the connecting cables is achieved without additional components and without additional expense in the assembly of the machine.

Direct current machine

A DC motor (), in particular for a blower device of a motor vehicle, having a pole housing (), a plurality of contact elements () effecting the bonding to a collector (), a pole housing opening () making it possible to feed electrical connection lines () through into the pole housing (), and an interference suppressor () serving to reduce and/or eliminate line-conducted electrical interference signals, in which the interference suppressor () has at least one leadthrough capacitor (), which is located in an electrical path of at least one connection line (). The invention further relates to an electrical interference suppressor () for an electrical device located in a housing, in particular for a DC motor () in a pole housing (), as well as to the use of a leadthrough capacitor () for interference suppression in a DC motor ().

DC motor with suppressor

An interconnection element for a multi-phase winding () that is made up of coils () and belongs to an electric machine, in particular a brushless mini motor, having a support () made of insulating material and conducting strips that are disposed on the support () for producing interconnections among the coils (). In order to reduce materials costs, the conducting strips are embodied in the form of bent wires (-) that are preferably contained in channels embodied in the support () and are fixed in place by means of two annular cover elements () made of insulating material.

Connecting element for a winding of an electric machine

In an electric motor-and-gear assembly for driving automotive power accessories such as front and rear wipers, power window units, or the like, having transmission casing, that can be closed by means of a casing cover, and having a socket that is disposed in the casing cover and can be contacted by means of a connector plug in order to connect the electric motor to the electrical system of the vehicle, for the sake of a uniform, single design of the socket when there are structurally varied designs of connector plugs, the socket is attached to an interchangeable adapter which has a first group of electrical contacts adapted to the socket and a second group of electrical contacts adapted to the connector plug. The contacts of the two contact groups, which are comprised of plug tabs, are connected to one another in an electrically conductive manner inside or along a surface of the adapter.

Interchangeable adapter for electric motor-and-gear assembly

In an electric-motor drive device for auxiliary devices in motor vehicles, such as sliding roofs, window controls, windshield wipers, and the like, having a gear housing ( ) and a cup-shaped motor housing ( ) that is slipped with its opening edge ( ) onto the gear housing ( ) and fixed thereon, to reduce manufacturing costs and the requisite installation space and improve force introduction from the motor housing ( ) to the gear housing ( ), the motor housing ( ), in its slip-on region, is roller-burnished into the gear housing ( ).

Electric-motor drive device

An electric motor-and-gear assembly for driving vehicle aggregates such as windshield and rear window wipers, power-window units and the like, having a transmission housing that can be closed by a housing cover. A motor housing that contains a commutator motor whose commutator protrudes into the transmission housing and cooperates with a brush holder fixed in the transmission housing. For the sake of a more reasonably priced manufacture and a time-saving, more rapid assembly of the brush holder, the commutator brushes are embodied as hammer brushes with spring leaf actuators prestressed toward the commutator. The spring leaf actuator are respectively fixed with their one actuator end in a U-shaped plastic carrying part of the brush holder, which is inserted into the transmission housing radial to the commutator, through the housing opening and is positioned in the transmission housing in a positively engaging manner by means of the housing cover.

Electric motor-and-gear assembly for vehicle accessories

An electric drive unit for vehicle systems, such as power windows and windshield wipers, having a commutator motor that has a commutator and at least two commutator brushes. The electric drive unit includes electrical components of an electronic system for the motor. To reduce production costs and simplify assembly, the electrical components are electrically secured to a lead frame that makes the electrical connection between the components and the commutator motor and the commutator brushes are embodied as hammerhead brushes, whose carrier plates are bent in one piece out of the lead frame.

Electric drive unit for vehicle systems

An electric drive unit having an electric drive motor and a transmission. The electric drive motor has an armature shaft which extends, for example, to a worm shaft of the transmission. The shaft is embodied of one piece with the armature shaft. A first bearing and a second bearing are provided to support the armature shaft. The second bearing is embodied as a ball bearing with an outer ring, an inner ring, and balls. The inner ring is press-fitted in a rotationally fixed manner onto the armature shaft. The outer ring is slid into a receiving bore disposed in the transmission housing and is pressed against an axial stop face adjoining the receiving bore by means of a retaining part that is supported in an installation channel and has flexible tongues that are directed toward the outer ring. This axial pressing can be produced in an easy-to-assemble fashion and is also inexpensive thanks to a low cost of the retaining part. The proposed electrical drive unit can be used, for example, for at least one windshield wiper of a vehicle.

Electric drive unit

The invention relates to a shaft and hub connection for securing bearings, in particular ball bearings (,), on a shaft (,). The proposal is made that the hub part (,) of the bearing (,) encompassing the shaft (,) have at least one axial surface (,), against which a projection (,) rests, which is produced from the shaft (,) by means of plastic deformation and prevents an axial movement.
