Abstract

Various embodiments include an isolation ring for isolating the end windings of a stator of an electrical machine, the isolation ring comprising: a protrusion with a conductor guide for receiving a conductor, wherein the protrusion comprises: a pressing flap with an inner guiding surface; and a pocket with a temperature sensor arranged in the pocket. The inner guiding surface faces the pocket. The pressing flap and the pocket are arranged so an end of the conductor inserted in the conductor guide is guided between the inner guiding surface and the temperature sensor, and the end is pressed against and/or guided to the temperature sensor.
