  • Method for determining the position of a rotor of an electric motor without sensors
    Patent number: 8138701
    Abstract: Disclosed is a method for detecting the current position of a rotor, in particular the angle of rotation of the rotor, an electromotor and a method for detecting the speed and/or the angle of rotation of an electromotor. The speed of the electromotor is hereby implied inter alia from the number of zero crossings of a comparison signal of the armature resistances or respectively conductances determined continuously in time and the average values of the armature resistances or respectively conductances determined continuously in time.
    Type: Grant
