METHOD FOR DETERMINING A MEASURING OFFSET OF A ROTOR POSITION SENSOR, CONTROLLER UNIT FOR AN ELECTRIC MACHINE AND ELECTRIC MACHINE FOR A VEHICLE

Method for determining a measuring offset of a rotor position sensor (5) assigned to a rotor (4) of an electric machine (1), comprising steps of - applying a short circuit to stator windings of the electric machine; - acquiring currents flowing into the stator windings (3) in the short-circuited sta...

Zusammenfassung:Method for determining a measuring offset of a rotor position sensor (5) assigned to a rotor (4) of an electric machine (1), comprising steps of - applying a short circuit to stator windings of the electric machine; - acquiring currents flowing into the stator windings (3) in the short-circuited state; and - determining the measuring offset depending on a q-current determined from the acquired currents.
