Tooth shape optimization for cogging torque reduction of transverse flux rotary motor using design of experiment and response surface methodology

The aim of this paper is to present optimal design process and optimized model of transverse flux rotary motor. The stator and rotor tooth shapes are optimized to reduce cogging torque. Design of experiment and response surface methodology are used as an optimization method and all the experimental samples are obtained from three-dimensional finite-element analysis. The validity of this method is verified by comparing the optimized model to the initial model.
