Magnetically-focused split integrated sensor and rotating speed, torque and angle calculation method

TLDR: In this paper, a magnetically focused split integrated sensor and a rotating speed, torque and angle calculation method was proposed for measuring and calculating rotating speed and torque of a shaft. But the sensor is not suitable for zero point finding.

Abstract: The invention provides a magnetically-focused split integrated sensor and a rotating speed, torque and angle calculation method, belongs to the technical field of sensors and solves the problem that existing sensors for measuring rotating speed, torque and angle of shafts have high size requirements on the shafts, poor matchability and difficulty in zero point finding. The sensor comprises a to-be-measured shaft and collection mechanisms, two ends of the to-be-measured shaft serve as a shaft input end and a shaft output end respectively, the collection mechanisms are arranged at the shaft input end and the shaft output end respectively, each collection mechanism comprises a rotor circuit board, a receiving coil, a shell and an exciting coil, each rotor circuit board and the corresponding receiving coil are printed on a receiving coil flexible circuit board, and a signal processing circuit is printed on each receiving coil. The sensor is mainly used for measuring and calculating rotating speed, torque and angle of a shaft.
