Zusammenfassung: | A device for operating an electric machine, it being possible for the electric machine to be at least operated in generator mode, having an electrical energy accumulator that is connected to the electric machine by an electrical circuit that has a main switch; the circuit having a motor brake circuit that is designed to feed the electrical energy generated by the electric machine in generator mode to the energy accumulator. It is provided that the motor brake circuit be designed to convert the electrical energy into heat in the case of a failure of the main switch, of a connection of the circuit to the energy accumulator and/or of the energy accumulator itself. |
