Abstract
A torque sensor can be configured to detect the positions of rotor targets relative to the position of respective receiver structures. A torque sensor can include an oscillator circuit coupled to an excitation coil. The oscillator circuit can be configured to generate a periodic voltage signal and energize the excitation coil with the periodic voltage signal. The inductive torque sensor can include a stator circuit board including receivers with receiver structures that are periodically repeated. The inductive torque sensor can include rotor targets coupled to respective rotors, the rotor targets can be configured to affect the strength of the inductive coupling between the excitation coil and the respective receivers. The inductive torque sensor can include processing circuitry configured to provide signals associated with positions of the rotor targets relative to their respective receiver structures.
