The technical scheme is based on the principle that the inductance of the stator changes along with the angle when the rotor rotates to realize detection; and a special insulating material and a brand new arrangement structure are adopted for the low-temperature operation of the sensor. Specifically, the mechanical and electrical structures are designed by adopting an inductance measurement method, so that the device structure can be obviously simplified; the low-temperature-resistant insulating material is adopted, and the sufficient mechanical strength can be ensured through the enameled wire, the insulating sleeve and the paint dipping process. In the detection process, alternating current or alternating voltage can be applied to the sensor coil, and after the generated alternating current or alternating current is measured, a signal processing circuit is used for outputting a low-frequency signal, a synthetic vector is obtained through Clark transformation, and the angle of the synthetic vector is calculated to obtain the angle of the sensor. The invention not only has good detection effect, but also obviously widens the applicable temperature range of the sensor, simultaneously does not need complex system construction, and can ensure lower product cost.
