Apparatus and method for sensing relative rotation |
摘要 |
A rotation sensor provided with a first rotor fixed to a shaft, a second rotor fixed to the same or other shaft and adjoining the first rotor, and a core having a resonance coil, arranged around the first rotor, and which coil forms a magnetic circuit working with the first rotor. The first rotor is formed of a magnetic material comprising an insulator; an irregular magnetic field is formed with the core; and the second rotor is provided with a conductor cutting across areas of different intensities of the irregular magnetic field in accordance with the difference of the angle of rotation when a difference in the angle of relative rotation occurs at a shaft position where the first rotor is fixed and at a shaft position where the second rotor is fixed.
