  • Device and method for operating a drive
    Patent number: 8800882
    Abstract: A device and a method for operating a drive having a mechanically commutated electric motor, is provided, wherein a rotary position of the drive is determined by a circuit from a ripple of a motor current of the electric motor, wherein at least one correction value is determined for an error characteristic of the electric motor, wherein at least one correction value is determined for an error characteristic of the electric motor, in that the drive is moved to a reference position that can be sensed by means of a position sensor, in that the drive is moved from the reference position into a plurality of positions at a distance from the reference position and at least one position deviation is determined by the circuit, and in that the correction value is determined from the particular position deviation and stored.
