METHOD FOR OPERATING AN ELECTRIC DRIVE UNIT, DATA PROCESSING DEVICE AND ELECTRIC DRIVE UNIT

Patent application, 2023

The disclosure relates to a method for operating an electric drive unit (10). The electric drive unit (10) comprises an electric machine (12) with a stator (14) and a rotor (16). The stator (14) comprises a set of phase windings. Moreover, the electric drive unit (10) comprises an inverter (18) for controlling the operation of the electric machine (12) by providing AC signals to the phase windings. The inverter (18) is electrically coupled to the phase windings. The method comprises triggering an AC drive signal for each phase winding of a first sub-set of phase windings such that the rotor (16) is rotated via the phase windings of the first sub-set. Additionally, the method comprises triggering a noise compensation measure for at least one phase winding of a second sub-set of the phase windings for compensating an undesired signal effect. Moreover, a data processing device (20) and an electric drive unit (10) with such a data processing device (20) are presented.
