摘要
The invention relates to a method and to a device for changing from the idle operating state of an electric motor (5) having three phase terminals (5-1, 5-2, 5-3) to a short-circuit operating state. Thereby significant voltage rises are avoided. For this purpose, after receiving (120) a request for changing of the operating state of the electric motor (5) to the short-circuit operating state, three switching elements (1-1, 1-2, 1-3) are closed. Thereby the switching elements (1-1, 1-2, 1-3) are at least partially closed successively and the times of closing the individual switching elements are predetermined as a function of control parameters of the electric motor.
