Summary:PURPOSE:To provide an AC servo motor controller having high current loop gain wherein a current command signal and a current feedback signal are matched in phase. CONSTITUTION:The AC servo motor controller comprises a first means 11 outputting a torque command signal, a second means 12 outputting a three-phase torque command signal, a third means 13 outputting a current command signal, a fourth means 14 for detecting the phase difference between a three-phase current feedback signal and a three-phase torque command signal, and a fifth means 15 for leading the phase of the current command signal according to thus detected phase difference.
