Optimization Design of Dual Three-Phase Synchronous Motor considering Mutual Magnetization Effects

This study elucidates the mutual effects inherent in the magnetic interplay between dual electrical systems within a Dual Three-Phase Permanent Magnet Synchronous Machine (DTP-PMSM). Such interactions can significantly alter the machine's operational characteristics, impacting the stability and efficiency of the system. Detailed examination of these interactions and an accurate representation of their influence on system behavior are critical for the engineering and modeling of DTP-PMSMs. Through finite element analysis, this paper investigates the consequences of cross-magnetization based on different winding configurations within a DTP-PMSM. The goal is to disclose how mutual inductance and the torque components of the dual winding sets affect each other. Utilizing constant permeability techniques, the study precisely quantifies these torque components. It delineates the isolation of mutual inductance using the frozen permeability method and advocates for an optimized winding approach to bolster overall machine performance.
