A synchronous machine drive control device such that a rotation angle correction amount can be detected even when a synchronous machine is rotating at high speed, and the rotation angle correction amount can be detected over a wide range, is obtained. A rotation angle correction amount calculation unit that calculates a correction amount of a rotation angle of a synchronous machine is included in an inverter control device, and the correction amount of the rotation angle is calculated based on a current detected by a current sensor by a three-phase short circuit being implemented in a state wherein the synchronous machine is rotating.
