Systems and methods for compensating for air gap sensitivity in torque sensors
Abstract:
A system may include a first sensor and a second sensor. The first sensor may include a driving pole that includes a driving coil that receives a driving current and emits a magnetic flux portion through a structure. The first sensor may also include a sensing pole that may include a sensing coil that receives the magnetic flux portion and generate a first signal based at least in part on the received magnetic flux portion. The first signal is based at least in part on a force on the structure. The second sensor may be disposed on the driving pole and may generate a second signal representative of a distance between the driving pole and the structure. The system may also include a circuit that may adjust the first signal based on the second signal.
