1. An electric machine comprising:
a stator having a winding comprising a first conductor; and
at least one temperature sensor arrangement comprising a temperature sensor device for detecting a temperature in a region of the winding, wherein:
ends of at least one part of the first conductor protrude beyond the winding,
one part of said ends is connected to an axial or radial interconnection ring placed on the winding, and
the interconnection ring comprises a second conductor and the temperature sensor arrangement is arranged on the second conductor and the temperature sensor device is thermally coupled to the second conductor;
the temperature sensor device comprises a sensor carrier within which a temperature sensor is fixed, the sensor carrier includes a form-fit contour configured to couple to a mating engagement contour of a carrier, such that when coupled the sensor carrier is fixed relative to the carrier, wherein the form-fit contour of the sensor carrier includes at least one cutout formed within a first end of the sensor carrier.
