Method for controlling an electrical machine (14), in particular for an electric or hybrid drive train (12) of a motor vehicle (10), wherein the electrical machine (14) can provide a torque (T) both at positive and at negative speeds (n), having the steps of:—using a characteristic curve (M; G) to check whether a torque desired value (72; 74) can or may be provided by the electrical machine (14), wherein the characteristic curve (M; G) represents a limit torque with respect to the speed (n) and has a first section (A1; A4) for positive speeds and a second section (A2; A3) for negative speeds. In this case, the first section (A1; A4) and the second section (A2; A3) are arranged in the same quadrant (I; IV) of the characteristic curve (70).
