An inverter device for controlling a permanent magnet motor includes: a voltage vector calculation unit that outputs a voltage command; a stabilizing compensation calculation unit that calculates a correction amount for reducing a current control gain at a rotational frequency component of the permanent magnet motor; a correction calculation unit that corrects the voltage command outputted from the voltage vector calculation unit based upon the correction amount calculated by the stabilizing compensation calculation unit; and a power conversion unit that converts DC power to AC power based upon the voltage command that has been corrected by the correction calculation unit, and outputs the AC power to the permanent magnet motor.
