1. An electric machine comprising a stator having a winding comprising a plurality of conductors assigned to one or more phases, which are connected to one another, as well as at least one temperature sensor assembly having a temperature sensor section with a temperature sensor for detecting a temperature in a region of the winding, wherein ends of at least one part of the plurality of conductors on an inner circumference or on an 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, to which at least one part of the plurality of conductors are connected, wherein the ends of at least two respective conductors of the plurality of conductors assigned to a phase protrude radially or axially outwards, to which at least one connection conductor is connected, which is also connected to a power connection arranged radially outside the winding, and wherein 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, wherein the housing recess is provided radially adjacent to a retainer configured to fix the at least one connection conductor.
