Abstract: The invention relates methods and devices for compensating for load factors in permanently excited motors, wherein the rotor position is determined from the inductivities of the phases. The methods and devices are characterized by a stabilization of the inductivity-based signals for the determination of the position of the rotor in permanently excited motors against load factors. To this end, advantageously current-dependent faults of the angular values determined during the operation of the motor are corrected. For this purpose, in order to correct the inductivity-based determination of the position of the rotor, in a measuring device either the phase currents are measured or the intermediate circuit current is captured.
