Abstract

In this paper, to decrease cogging torque and operating torque ripple, a barrier was installed on the rotor. Also, optimized design was carried out by Design Of Experiment(DOE) and various characteristics including torque were studied by the Finite Element Method(FEM). The modal analysis of the stator was performed and the natural frequency was calculated. The analysis of displacement by the Radial Magnetic Force(RMF) was analyzed and the effects according to the rotor shape were compared. In addition, the validity of this approach was established through experiments showing vibration reduction due to the optimized barrier design.
