Displacement sensing method and motor control apparatus

---

Abstract

---

A displacement sensing method of the present invention includes the steps of superimposing a predetermined signal on a torque command to supply a drive torque to a motor, measuring an amplitude spectrum ratio between the drive torque in superimposing the predetermined signal on the torque command and a motor angle measured by a displacement sensor, generating correction data for evening out the amplitude spectrum ratio, and correcting the measured motor angle so that the motor angle measured by the displacement sensor is equal to an actual motor angle using the correction data.
