Cogging Torque Reduction in Surface Permanent Magnet Motors Using Taguchi Experiment Design and Finite Element Method

Abstract

in this paper, use the Taguchi experiment design method for achieving optimal design to reduce cogging torque and torque ripple of a surface permanent magnet motor. Cogging torque is one cause of vibration and noise, so reducing cogging torque is an important issue Results from simulations, indicate reduction of cogging torque and torque ripple while increasing the average of motor's output torque. How do simulations and achieve the optimum design, by using the Taguchi method and simulations by using the finite element method has been done.
