Abstract :
A toroidal wound flux-switching permanent magnet machine with large air-gap (δ = 3 mm) for a medium speed application (nominal speed n = 6000 rpm) is designed by means of 2D-Finite Element Analysis. The aim of the research is to integrate aluminum flat wire as an alternative winding type to reduce the weight as well as the high frequency winding losses of the machine. Moreover, a multi-physical approach regarding the simulation in FEMM is presented. The toroidal wound flux-switching permanent magnet machine is compared to an equally sized E-core design and pros and cons of both designs are investigated.
