Abstract:
The invention relates to a method for operating an electric machine which can be operated using PWM control (A1) and using block control (A3), wherein a transfer control (A2) is used for transfer between the PWM control (A1) and the block control (A3), in which method, within the scope of controlling a torque of the electric machine, a d value of a phase voltage is set as a manipulated variable and a q value of the phase voltage is changed continuously.
