Abstract

An electric machine includes a stator having a winding including a plurality of conductors assigned to one or more phases and at least one temperature sensor assembly having a temperature sensor section with a temperature sensor for detecting the temperature of the winding. The ends of at least one part of the conductors on the inner or outer circumference of the winding protrude axially or radially over the winding, wherein an interconnection ring comprising at least one conductor bridge is placed axially or radially on the winding. The ends of at least two respective conductors assigned to a phase protrude radially or axially outwards. The temperature sensor section has a sensor housing which is introduced into a housing recess provided on the interconnection ring in such a way that the temperature sensor is in thermal contact with the connection conductor or the conductor bridge.
