반응표면설계법을 이용한 자동차 펌프용 IPMSM의 토크리플 및 THD 최적설계

Abstract

This study presents optimum design of IPMSM for vehicle pump using Response Surface Methodology(RSM). In the electric motors of vehicle system, reducing noise/vibration is one of the most important issue in designing electric motors. In initial design, pole/slot combination of the prototype is determined by using Noise & vibration order to reduce radial force in airgap of the motor. The optimization conducted by using RSM. The objective functions are back-electromotive force(BEMF) and Total Harmonic Distortion(THD) of the BEMF. The design variables are slot open, eccentricity and pole angle. The validation of the electric motor will be verified by 2-D FEA.
