A Rotor Initial Position Estimation Method for Surface-Mounted Permanent Magnet Synchronous Machine

A new rotor initial position estimation method for surface-mounted permanent magnet synchronous machines (SPMSM) is presented in this paper. The proposed method is based on the magnetic saturation effect and is suitable to prevent starting failure and reverse rotation. Compared with conventional met...
