The detector includes a magnetic flux guide with two cylindrical bars (31,32) placed parallel to each other and opposite a magnetic field whose angular position is to be measured. An insulating wall (33) separates the magnetic field area from a second area which houses a Hall effect sensor (39). The sensor is connected to a processing module which generates a signal corresponding to the angular position of the rotating field relative to the position of the guide. The gap between the two bars making up the guide (hg) is slightly larger than the gap between the two magnets (36,37) generating the rotating field. |
