DEVICE AND METHOD FOR CONTROLLING AN ELECTRIC MACHINE

The invention provides a device () and a method for controlling an electric machine (). The method comprises the steps of: providing (S) a desired torque value () for a torque to be exerted by the electric machine (); determining (S) a fault signal () which indicates a fault state of the electric machine (); determining (S) a current rotor angle value () of the electric machine (); determining (S0) a fault state operating point () on the basis of the desired torque value () provided, the determined fault signal () and the determined current rotor angle value (); and shifting or moving (S) an operating point, at which the electric machine () is operated, from a normal state operating point () to the determined fault state operating point ().
