A detection and control device is provided for detecting a motor fault of an electric motor with star point topology, with an evaluation unit, a control unit, and a return unit. The return unit is configured for returning a star point potential of the electric motor to the evaluation unit, the evaluation unit is configured for evaluating the star point potential and the control unit is designed for passivating a motor fault on the basis of the evaluation. The function of the return unit and of the evaluation unit may also be assumed by control lines and by the control unit.
