Generalized Control Scheme for Dual Three-Phase PMSM Under Normal and Postfault Operation

Boyuan Zheng, Xinyuan Wang, Yongxiang Xu, Lu Wang et autres

Dual three-phase permanent magnet synchronous motors (DTP-PMSMs) are particularly suitable for high-speed motors due to their medium-voltage, high-current characteristics and postfault-operation ability. However, the fault diagnosis process at high speed can greatly affect the normal operation. This paper proposes a generalized control …
