Abstract
A power conversion device includes processing circuitry that estimates a magnet magnetic flux of an electric motor based on a d-axis magnetic flux generated in the electric motor, a d-axis inductance of the electric motor, and a d-axis current flowing in the electric motor, estimates a q-axis inductance of the electric motor based on a q-axis magnetic flux generated in the electric motor and a q-axis current flowing in the electric motor, estimates a drive force of the electric motor based on the magnet magnetic flux and the q-axis inductance, and corrects a current command such that the drive force follows a drive force command.
