Experimental Evaluation of Flux–Weakening Capability of Dual Three-Phase Synchronous Reluctance Motor

A dual three-phase synchronous motor is considered as a fault-tolerant solution for a hybrid electric vehicle. The study presented here compares the characteristics of the motor under nominal and flux–weakening operations in different operating conditions such as healthy, half control, and post-fault conditions. The post-fault characteristics are analyzed under open-circuit faults of a three-phase system and short-circuit faults of a three-phase system. All the results are validated by experimental tests.
