摘要：The disclosure relates to a magnetic device for detecting the absolute positionof an input shaft capable of rotating more than 360°, the device including a main magneticsensor, a motion reducer, and a secondary magnetic sensor, wherein the main magneticsensor is connected to a rotor, measures the rotation of the shaft for ranges of angles ofless than 360°, and includes a main magnet, the motion reducer converts the rotation ofthe shaft into a reduced rotation, the maximum amplitude of which is equal to no morethan 360°, and the secondary magnetic sensor measures the reduced rotation andincludes a secondary magnet. According to the disclosure, the secondary magnet isarranged between the upper and lower planes of the main rotor, and the main magnethas P pairs of poles, where P is greater than 1.
