Optimization of Transverse Flux Motor Coupled with Switched-mode Power Converter

The aim of this paper is to present the optimization of outer rotor permanent magnet transverse flux motor (TFM) using design of experiments. The 3-D time-stepping finite-element analysis (FEA) is used to calculate electromagnetic torque regarding variation of TFM geometric parameters. Further, in 3-D time-stepping finite-element analysis the TFM model is coupled with an external three phase current source which was used as to present the switched-mode power converter with pulse width modulated voltage. The main objectives of TFM geometry optimization are maximization of nominal electromagnetic torque and minimization of torque pulsations. All two optimization targets should be realized in one TFM design.
