This paper investigates the fault-tolerant capability of a number of 30 kW permanent magnet (PM) machines with fractional-slot concentrated windings (FSCWs) when connected to two types of modular type converters recently proposed in the literature. Due to the strong PM rotor magnetization when using NdFeB-type magnets, the resulting short-circuit currents during a converter submodule short-circuit was found to be larger than the rated current which, potentially, may cause the machine to overheat. Reducing the PM rotor magnetization will reduce the short-circuit current but also affect the constant power speed range (CPSR). The results further highlight the importance of a tailored design specification when designing FSCW PM machines in automotive applications.
