Multiphase machines have been used widely in electric ship propulsion, air-craft drives, locomotive traction, and high-power industrial applications. The fault-tolerant capability is one of the most interesting topics in multiphase stand-alone motor drives since no additional hardware is required to provide the additional degree of freedom if they are properly configured. The fault-tolerant control strategies, suitable for open-phase fault operation of five-phase concentrated-full-pitch winding induction motor drives, are studied in this paper. In order to compare the performance of the above strategies, a more general mathematical model considering third harmonic component based on symmetric component theory is established. Then expressions of the average torque, torque ripple, total copper loss and efficiency are derived. Finally, comparative results can be used as guidelines for the engineering application.
