Title:
回転する部材の絶対角度位置を360°にわたって決定するためのセンサ
Document Type and Number:
Japanese Patent JP4406639
Kind Code:
B2
Abstract:
The invention relates to an angular position sensor. It relates to a sensor that comprises a rotating part ( 14 ) which creates a variable magnetic flux, a fixed part ( 16 ) for supporting two probes ( 22, 26 ) each having an output current, the first ( 22 ) of the probes having an output current having discontinuities when the magnetic flux passes through zero, the second ( 26 ) of the probes being subjected to a second magnetic flux, shifted by 90° relative to the first flux and having an output current that is a continuous function of the magnetic flux, and a device ( 30 ) for adding the currents from the two probes. The range of variation of the current from the first probe ( 22 ) is slightly larger than the range of variation of the current from the second probe ( 26 ). Application to engine camshafts.
