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.
