Copper Loss Reduced Fault-Tolerant Control for Dual Three-Phase PMSMs --- Abstract Dual Three-Phase Permanent Magnet Synchronous Motors (DTP-PMSMs) provide increased fault tolerance and reliability for applications such as electric vehicles and aerospace systems. However, existing fault-tolerant control (FTC) strategies often increase copper losses under open-phase faults due to imbalanced current injection or suboptimal control methods. This research builds upon existing FTC designs by developing a copper loss minimization strategy that sustains motor torque and efficiency. The proposed scheme leverages optimized current reference recomputation and zero-sequence current injection to minimize copper loss while mitigating torque ripple. MATLAB/Simulink simulations validate the method under open-phase faults, demonstrating improved energy efficiency, torque performance, and reduced copper losses. Methods from optimization-based and analytical models streamline the implementation of the s
