A motor control device includes an estimator for estimating a rotor position of a motor having a salient pole by using a value corresponding to a q-axis inductance of the motor as an operation parameter where an estimated axes for the control corresponding to d-q axes are gamma-delta axes, and a controller for controlling the motor based on the estimated rotor position. The estimator generates a deviation between a d-axis and a gamma-axis by performing the estimation of the rotor position based on a value between a real q-axis inductance and a real d-axis inductance of the motor adopted as the operation parameter. The controller controls the motor so that a gamma-axis component of a motor current supplied to the motor is maintained to be a predetermined value of zero or close to zero regardless of a value of a delta-axis component of the motor current.
