Abstract (en)

[origin: WO2007077389A2] System for detecting the angular position of a rotating element with respect to a non-rotating element, comprising an annular encoder 4 provided with a number P of poles greater than or equal to 2, intended to be fixed to one of the rotating or non-rotating elements, and a number N of sensors, with N greater than or equal to 3, which are able to receive a signal originating from the encoder and are mounted on the other of the non-rotating or rotating elements facing the said rotating or non-rotating element and angularly distributed, and at least one subtraction module capable of processing at least two output signals from the sensors in order to generate a differential signal.
