Method for determining and/or controlling a position of an electric motor

9:

• The method of claim 8, wherein an absolute position of the electric motor is transmitted by the sensor system via the serial peripheral interface protocol signal or the pulse width modulation signal to the analysis unit when the electric motor is started, whereupon the electric motor is then supplied with current via a commutation derived by the analysis unit from an incremental position of the rotor of the electric motor.

10:

• The method of claim 9, wherein a pulse to no-pulse ratio of the pulse width modulation signal is analyzed to transmit the absolute position of a pole pair of the rotor of the electric motor.

11:

• The method of claim 9, wherein a comparison is carried out between an incremental position of the rotor calculated by the analysis unit and the absolute position of the pole pair.

12:

• The method of claim 11, the comparison is carries out cyclically.

13:

• The method of claim 8, wherein a small-diameter magnetic transmitter ring fastened to the rotor of the electric motor which has only one pole pair is used to determine the position of the rotor.

14:

• The method of claim 13, wherein the magnetic transmitter ring having a larger diameter and a plurality of pole pairs, fastened to the rotor of the electric motor, is used to determine the position of the rotor, where the number of pole pairs of the magnetic transmitter ring is equal to the number of pole pairs of the rotor.
