摘要

The invention relates to a method or a device for load-free determining of load-dependent positioning parameters of a synchronous machine without a position sensor, which is controlled via pulsed terminal voltages from which, and in combination with the measured current response, the inductance or admittance is calculated or wherein from the load-free lowest and the load-free highest differential inductance are known, wherein based on the load-free lowest and the load-free highest differential inductance and the short-circuit current, the magnetic saturation behaviour under the load of the absolute inductance and/or the magnetic anisotropy of the synchronous machine is predicted and used in the position-sensor-free control operation for positioning.
