An electrical drive unit has a housing having a metal pole housing, which accommodates a stator and a rotor, and a separately produced electronic housing which axially adjoins the pole housing and accommodates an electronic unit. At least one contact element is integrated inside the electronic housing and forms, via at least one ground pin, an electrically conductive connection between the electronic housing and the pole housing to establish a ground connection. An open flange and a cylindrical circumferential wall are formed on the pole housing, against which circumferential wall the at least one ground pin radially bears in a resilient manner, and the at least one ground pin has a side surface facing the circumferential wall, wherein a bearing contour is formed on the side surface and bears against the circumferential wall only in an approximately punctiform manner with respect to an axial direction and/or a circumferential direction.

The invention relates to a stator () of an electrical machine (), to an electrical machine (), and to a method for producing same, particularly for adjusting movable parts in a motor vehicle, comprising a pole casing () to the inner wall () of which winding holders () carrying electric coils () are applied, the winding holders () comprising a stator tooth () which is formed on a yoke element () which is radially applied to the inner wall (), and an insulating mask () is arranged on the winding holder (), which insulates the electric coil () from the winding holder (), and the insulating mask () extends with an axial projection () axially over the yoke element (), the axial projection () being radially applied to the inner wall () of the pole casing () with a shoulder () extending in the peripheral direction ().

Stator of an electrical machine, an electrical machine, and method for producing same

The invention relates to an electric parking brake, comprising a motor-gearing unit () with a drive output shaft (), wherein the motor-gearing unit () generates a rotation of the drive output shaft (), and comprising a spindle device () having a spindle () and a nut (), wherein the spindle device () converts the rotation of the drive output shaft () into an axial movement of the nut () in the axial direction (X-X), wherein the spindle () is connected in a positively locking manner to the drive output shaft (), the spindle () is centered on the drive output shaft (), and the spindle is mounted in a brake caliper ().

Electric parking brake

A rotor of an electrical machine has at least one hollow-cylindrical, first permanent magnet with axial bearing surfaces that interact with at least one retaining element and with a sensor magnet assembly, and the first permanent magnet and the sensor magnet assembly are retained axially between two retaining elements.
