Abstract
The invention relates to a method for detecting the rotary angle positions (α, β) of rotating parts of a wiper motor, the wiper motor having a brushless electric motor as a first part which comprises a rotor rotating about a first axis of rotation and which drives a gear wheel as a second part which rotates about a second axis of rotation and which comprises a driven shaft, and the rotary angle positions (α, β) of the two rotating parts being detected by means of two sensor devices each having a signal generating element and a sensor element for detecting a changing physical parameter of the signal generating element.
