Abstract
An electric machine includes a stator having a winding, and at least one temperature sensor for detecting the temperature in the region of the winding. The temperature sensor is arranged on an elongate support that is elastic at least in the region of the temperature sensor. The support is placed in an elongate recess which is open to at least one of the sides of the windings and the temperature sensor is pressed into thermal contact with the winding by the support.
Claims14
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.
An electric machine comprising:
- a stator having a winding;
- at least one temperature sensor configured for detecting a temperature of the winding;
- and
- an elongate support comprising:
- a groove-like receiving section on an upper side that is open on one end and includes a stop on the other end, wherein the temperature sensor is received in the receiving section via the open end and abuts the stop;
- a leading end inserted into a recess of the winding, wherein the temperature sensor is pressed into thermal contact with the winding by the support;
- and
- a first spring arm and a second spring arm formed in the leading end defining a slot therebetween, wherein the first spring arm and the second spring arm are configured to be spring loaded and force the temperature sensor away from the slot to press against the winding.
