Abstract:
The invention relates to an electric motor comprising a rotor and a stator, the hollow cylindrical stator of which has a distributed winding consisting of multiple circumferential coil layers arranged one over the other in layers with a winding head. A temperature sensor for detecting a winding head temperature is arranged in the winding head. A dimensionally stable sensor receiving element with a functional section having a receiving area for the temperature sensor is provided which is added between two adjacent coil layers arranged one over the other such that the functional section is fixed in the winding head between the two coil layers that are spread apart by the introduction of the functional section and that the temperature sensor can be inserted into and removed from the receiving area through an opening arranged in a base section of the sensor receiving element, wherein the receiving area is delimited on one hand sectionally by the functional section and on the other hand sectionally by the winding. In addition, the invention relates to a method for producing an electric motor comprising a stator and a rotor.
