Abstract
An electric machine includes a protective isolation module which is accommodated in a machine housing. The protective isolation module includes an input interface which is electrically connected to a temperature sensor to receive an electrical sensor signal generated by the temperature sensor as a measure of a machine temperature of the electric machine, an output interface which is galvanically isolated from the input interface to realize a secure electrical protective isolation of the output interface from a voltage flashover of a machine winding in the sensor power circuit, and a supply interface, via which the protective isolation module can be supplied with electrical energy from a power supply for the electric machine. An electronic control system receives an output signal that replicates the sensor signal via the output interface for evaluation in the electronic control system.
