Stator　winding　inter　turn　short-circuit　fault　is　one　of　the　most　common　internal　faults　of　fault-tolerant　machine,　which　can　disconnect　the　fault　phases　and　keep　operating　correctly　in　the　event　of　a　failure.　Stator　winding　short-circuit　fault　model　is　established　through　analysis.　Based　on　finite　element　method,　the　high-power　density　fault-tolerant　machine　internal　magnetic　field　simulation　and　analysis　is　implemented　using　Maxwell2D　and　induced　voltage　frequency　spectrum　is　analyzed　by　FFT　method.　The　characteristics　of　stator　winding　short-circuit　faults　are　summarized,　which　lay　a　solid　foundation　for　fault-tolerant　machine　earlier　faults　prediction　and　winding　switching.
