Optimal Design of Line-start Permanent Magnet Motor for High efficiency Performance with double-barrier rotor design

단상 유도형 동기 전동기의 효율 향상을 위한 회전자 형상 최적화

This paper examines an design of double-barrier rotor structure for improving the efficiency performance in a single-phase line-start permanent magnet(LSPM) motor. By utilizing the advantages of double-barrier rotor design that by increasing reluctance torque generation to compensate magnet torque production, the copper loss reduction is achieved. The optimal approach of response surface methodogy(RSM) is performed for determining a optimum double-barrier rotor structure. The improving of efficiency performance is confirmed by finite element method(FEM) and test.
