ISG용 매입 형 영구자석 동기전동기의 분포권 모델과 집중권 모델의 최적설계 및 특성해석

This paper deals that the optimal design of integrated starter and generator(ISG) which is one of the most important parts of hybrid electric vehicle. The interior type permanent magnet synchronous reluctance motor which energy density is relatively higher than other types of motors is employed to optimal design. The optimal design is performed using design of experiment related with response surface methodology. Two wining types, distributed and concentrated type, is considered to optimal design. ISG is operated not only motor in low speed region but also generator main driving region of the vehicle. Therefore the object function of optimal design is decided that output torque and improving the total harmonic distortion to maximize generating efficiency. The d, q axis equivalent circuit analysis is performed to calculate characteristics such as torque, power, line current and efficiency according to operating speed.
