 like figure 2As shown, this embodiment includes: a fixed sleeve 1, a rotating shaft 3, a magnetic bias permanent magnet 4, a magneto-deformable body 5, a force conversion body 6, an excitation permanent magnet 7 and a sensor body fastener 8, wherein: the fixed The sleeve 1 and the rotating shaft 3 are sequentially socketed from the outside to the inside, the excitation permanent magnet 7 is arranged on the rotating shaft 3, the magnetic bias permanent magnet 4, the magnetic deformation body 5, the force conversion body 6 and the sensor body fastener 8 are sequentially arranged They are fixedly connected in series and arranged on the fixed sleeve 1.
 The excitation permanent magnet 7 is arranged on the outer end surface of the rotating shaft 3. In this case, rotating the rotating shaft 3 or directly rotating the permanent magnet 7 (such as rotating by hand) can also realize the corresponding function that can be detected in embodiment 1.
 like image 3 As shown, the rotating shaft 3 described in this embodiment has a tubular structure, and the outer casing 1 and its sensing body are placed inside the rotating shaft 3 to realize various sensing functions described in the above embodiments.
 Through the above-mentioned device and implementation technical link, this device generates the change of the corresponding electric / magnetic signal by detecting the force conversion body 6 on the sensing body excited by the excitation permanent magnet 7 during the rotation process. The sensor of the proposed device for the rotation of the rotating shaft can be used as a torque sensor for the rotating shaft under the rotation angle or quasi-static torque. Secondly, by calibrating the corresponding relationship between the generated electric / magnetic signal and the excitation permanent magnet 7, that is, the rotation angle or the phase change of the rotation cycle of the rotation shaft 3 before and after the est...
