Abstract :
This paper investigates the thermal behavior of a five-phase fault tolerant permanent magnet vernier (FTPMV) machine under healthy and faulty operating conditions. The losses of the FTPMV machine in healthy and faulty cases are calculated and analyzed at first. Then, thermal analysis of the FTPMV machine is performed by using finite-element method. The simulation results verify that the FTPMV machine can operate safely in healthy and faulty cases from the point of view of thermal limits, which benefits from the fault tolerance design. In addition, the results of thermal analysis also verify that the design of FTPMV machine is feasible and reliable.
