Abstract
A rotary device includes a stationary member, a rotary member, a sensor device including a sensor rotor, a first sensor, and a second sensor, and a processing device. The first sensor is configured to output a waveform signal that is delayed in phase when the rotary member is displaced relative to the stationary member. The second sensor is configured to output a waveform signal that is advanced in phase when the rotary member is displaced relative to the stationary member. The processing device is configured to calculate a displacement of the sensor rotor based on a difference between a first rotation angle and a second rotation angle, to correct the calculated displacement, and to calculate a load acting on the rotary device from the corrected displacement.
