Abstract: This research presents an enhanced fault-tolerant control strategy for nine-phase induction motor drives intended for electric vehicle (EV) applications. Multiphase motors, especially nine-phase configurations, offer superior fault resilience and performance compared to traditional three-phase systems. The study develops a sensor less, real-time fault detection and compensation algorithm capable of addressing various fault conditions, including phase loss, open-circuit, and short-circuit faults. Simulation using MATLAB/Simulink demonstrates the effectiveness of the proposed strategy. The results highlight improved system efficiency, torque stability, and operational continuity under fault scenarios. Compared to conventional methods, the proposed strategy significantly reduces torque ripple, shortens recovery times, and enhances motor lifespan. These findings underscore the potential of the strategy for deployment in modern EV platforms where reliability and fault management are critical.
