This paper proposes a new compensation method that can efficiently compensate errors appearing in the phase estimate by the high-frequency voltage injection methods for sensorless drives of permanent-magnet synchronous motors. In the proposed method, the phase estimate is supposed to be determined by high-frequency components of stator current in the rotational reference frame aiming to be in phase with the rotor phase.
