The Design of Radial Magnetic Force Equilibrium for Reduction of Vibration in IPM Type BLDC Motor Lee, Gyeong-Deuk; Lee, Won-Sik; Kim, Gyu-Tak;
In this paper, the vibration source of IPM type BLDC motor was analyzed by finite element method. The main causes of the electrical vibration were RMF(Radial magnetic force) and cogging torque. It was designed model of minimized cogging torque and RMF equilibrium. Design models were selected the optimum model using the design of experiment method. And, the vibration experiment was carried out through prototype machine of each model. Finally, the experimental results were compared with the analysis ones.
