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