Abstract

The invention relates to a method (400) for calibrating the control of an electrical machine (120) for a specifiable torque value (T_Des), the electrical machine (120) being operated by means of field-oriented control. The method comprises the steps of: a.) specifying a current vector (Ix_V) (410) for producing the specifiable torque value (T_Des) by means of a connectable electrical machine (120), b.) specifying a test signal (Sx_Test) (420) and superimposing the test signal (Sx_Test) on the current vector (Ix_V), c.) capturing (430), by means of a sensor (130), a response signal (Sx_Antw) resulting from the superimposing, e.) determining (450) a calibrated current vector (I_Vk) according to the evaluation of the response signal (Sx_Antw).
