An induction motor control device includes a power conversion circuit, a current sensor, a current component calculation circuit for calculating first and second current components, a magnetic flux command calculation circuit for calculating a magnetic flux command value such that the amplitude ratio between a squared value of the first current component and a squared value of the second current component takes a preset value, a voltage component calculation circuit for calculating a primary voltage component command value, and a primary voltage component command calculation circuit. The current component calculation circuit calculates first and second current components in phase and 90° out of phase with the primary voltage component command value, respectively.
