Abstract
A system for monitoring the temperature prevailing in the stator unit of an electric drive includes a temperature sensor that is integrated into the windings of the stator unit and that transmits a temperature-dependent sensor signal. The sensor signal may be injected via an electrical transmitter unit into the signal processing unit of a position measuring device connected to the drive.
