Abstract:
A motor control device for controlling a three-phase AC motor by using dq-three-phase coordinate conversion includes a phase correction amount calculation unit for calculating a phase correction amount by using a detected motor speed and a q-axis current command initial value, a rotor phase angle correction unit for adding or subtracting the phase correction amount to or from a detected rotor phase angle of the motor to calculate a corrected rotor phase angle, and a coordinate conversion unit for performing coordinate conversion between parameters on a dq coordinate system and parameters on a three-phase coordinate system on the basis of the corrected rotor phase angle.
