Provided is a synchronous machine drive control device that can detect a rotation angle correction amount and enables the detection of the rotation angle correction amount in a wide range, even if a synchronous machine operates at a high rotation speed. An inverter control device (19) is provided with a rotation angle correction amount calculation unit (19h) that calculates a correction amount fora rotation angle of a synchronous machine (12). A three-phase short circuit is executed while the synchronous machine (12) is rotating, and the correction amount of the rotation angle is calculated on the basis of the current detected by a current sensor (20).
本发明得到一种同步电机驱动控制装置,即使在同步电机处于较高转速的情况下也量能检测旋转角度校正量,能在较宽范围内进行旋转角度校正量的检测。逆变器控制装置(19)中包括运算同步电机(12)的旋转角度的校正量的旋转角度校正量运算部(19h),所述旋转角度的校正量基于在同步电机(12)旋转的状态下实施三相短路、并由电流传感器(20)检测的电流来运算。
