Analysis of the Saliency Ratio Effect on the Output Torque and the System Efficiency in IPM Drives
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 Permanent magnet synchronous motors (PMSM) can be classified into two groups based on the rotor saliency structure as surface mounted permanent magnet synchronous motors (SPM) and interior mounted permanent magnet synchronous motors (IPM). Saliency ratio
