ABSTRACT:
A method for controlling an electric motor for an automobile wiper system includes a calibration curve in which data is converted into the angular value of the position of an output shaft and a correction is made depending upon a direction and magnitude of deviations. The electric motor has a stator with a lid with permanent magnets and the output shaft has a worm wheel with pole extensions of permanent magnets and a sensor of the angular position of the output shaft.
