Abstract	In this paper, cogging torque and unbalanced RMF which occurred in IPM type BLDC motors were investigated regarding as the effect of vibration. The main causes of electromagnetic vibration were the cogging torque and strength of Radial Magnetic Force(RMF). The minimized cogging torque model with notch and the equilibrium RMF model was designed using Design of Experiments(DOE) to reduce vibration. The mentioned models above and the basic model were compared with each other through Finite Element Analysis(FEA) and experiments. As a result, it was conformed that unbalanced RMF affected vibration. And RMF equilibrium is much more effective to vibration than reduction of cogging torque.
