A stator for an electric motor having stator teeth arranged about an axis of rotation, which are each wound with a winding, and at least one heat-conductive contact element, wherein the at least one contact element extends in the axial direction from a region adjoining the windings in the axial direction in each case between two windings and is formed to be deformable and/or deflectable in the circumferential direction for direct contact with at least one of the windings. The windings are overmolded or remolded with an electrically non-conductive material forming an encapsulation, which material forms with the at least one contact element in each case a pocket for receiving a temperature monitoring element which can be inserted in the axial direction, the winding-side wall of which is formed at least in a section by the contact element directly abutting the winding.

Stator for an electric motor with at least one pocket for receiving a temperature monitoring element

A switching disk for contacting windings of a stator of an electric motor, which windings are arranged around an axis of rotation, with a printed circuit board of the electric motor, wherein the switching disk has an annular support structure circumferentially extending around the axis of rotation and multiple contact arrangements for contacting the windings with the printed circuit board, which are held by the support structure. The contact arrangements are each formed by a winding contact for contacting one of the windings, a printed circuit board contact offset therefrom in the radial direction for contacting the printed circuit board, and a coupling element extending in the radial direction and electrically connecting the winding contact to the printed circuit board contact.
