1. An electric machine comprising:
a stator having a winding and at least one temperature sensor for detecting a temperature in a region of the winding,
wherein the temperature sensor is arranged on an elongate support that is elastic at least in a region of the temperature sensor, wherein the support is slotted in a region of a leading end to form an upper spring arm and a lower spring arm, the temperature sensor is arranged on at least a portion of an outwardly facing surface of the upper spring arm, and
wherein the support is placed in an elongate recess which is open to at least one side of the winding and the temperature sensor is pressed into thermal contact with the winding by the upper spring arm of the support.
