Abstract :
The use of an hybrid stator, made of a combination of Fe-Si laminations and soft magnetic materials (SMC), has been recently proposed to reduce the iron losses occurring in a clawpole transverse flux machine (CTFM). In this paper, we show that a very low-loss magnetic material, the amorphous material, can be easily used as a substitution to the Fe-Si laminations to reduce the losses further. The stator iron losses in a CTFM with amorphous cores are compared to those occurring in a CTFM with Fe-Si cores by experimental tests and finite element simulations. It is found that the use of amorphous cores could increase the machine efficiency and speed range.
