Design and Analysis of a Five-Phase Permanent-Magnet Synchronous Motor for Fault-Tolerant Drive

Reliability is a fundamental requirement in electric propulsion systems, involving particular approach studies on system failure probabilities. An intrinsic improvement to the involves introducing robust architectures such as fault-tolerant motor drives these systems. Considering potential for hardware failures, design will achieve reliability objectives without recourse optimized redundancy or over-sizing system. Provisions planned degraded modes of operation are designed operate mode, which makes them different from pure approach. This article presents how five-phase permanent-magnet synchronous operates under one- two-phase faults, and reconfigures post-fault currents meet torque speed reliable that meets requirements an
