A novel complementary and modular tubular permanent magnet flux-switching motor
A complementary and modular tubular flux-switching permanent magnet (CMTFSPM) machine is proposed and investigated, which is constituted of several modular units. Finite element analysis (FEA) is used to investigate and compared the flux linkage, back-EMFs, detent force, self and mutual inductances and thrust performance with the existing tubular permanent magnet motor. The results reveal that the proposed CMTFSPM machine can offer symmetrical back-EMF waveforms, smaller cogging force, lower force ripple, and higher magnet utilization factor than the existing one.
