This paper proposes new simple realizations of the “Mirror-Phase Estimation Method (MPEM)” used for estimating the rotor phase in the sensorless drive of salient-pole permanent-magnet synchronous motors. The proposed realizations involve the use of the stator current induced by high-frequency voltage injection. The MPEM has the following advantages: 1) It is versatile, i.e., it can be applied to almost all voltage injections. 2) It makes the most of the positive correlation between the rotor phase and the high-frequency current. 3) It does not require knowledge of motor parameters. 4) It does not require redesigning the combined PLL when the amplitude and/or frequency of the injected high-frequency voltage is changed. However, the MPEM has drawback; it has a relatively large computational load. This paper proposes three simple realizations of the MPEM in which the computational load drastically reduced. The validity of the realizations is shown by conducting numerical experiments.
