Abstract: A stator of an electric machine has an annular stator body with a multiplicity of winding slots. The winding slots protrude into the stator body in the manner of a pocket from a ring interior. Respective windings are disposed in the winding slots and the slots are sealed toward the ring interior with slot-liner elements. The slot-liner elements of all the winding slots are combined to form a slot-liner cage. The slot-liner cage is formed with circumferential cage rings at the ends of the slot-liner elements. The cage rings have an interruption at a circumferential point. The circumferential point has a self-retaining lock geometry which prevents an autonomous opening of two intermeshing ring ends of the cage rings.

Abstract: An electric motor, particularly an engine of a motor vehicle, has a temperature sensor for monitoring the operating temperatures of a winding. The temperature sensor is inserted through a radial through-hole at the periphery of the insulation element into a recess which is delimited between a shaped-out portion on the corresponding projection of the insulation element and the winding. The shaped-out portion has a slope so that a translational displacement of the temperature sensor at the same time leads to an increase in the biasing force of the temperature sensor with respect to the winding. It is thus possible to ensure the desired pre-tension force, and therefore a reliable contact surface between the temperature sensor and the winding, as a result of the connecting force and, at the same time, secure the temperature sensor with force fit in the shaped-out portion.
