하이브리드 자동차용 고전압 전동압축기 모터 개발

As key industry, the automobile industry is a technology-intensive industry developing rapidly to comply with the demands of consumer. In this paper, the motor development of high voltage electric compressor for hybrid car is presented. In the first place, optimal design of the motor has been conducted. In order to find optimal solution, Taguchi method was used and Output power, Torque-Ripple, Cogging-Torque were considered in optimization process. Also, stress simulation was conducted to prevent the problems in mass production. The weight balance was designed and applied to the motor since the high voltage electric compressor has unbalance. Finally, through the comparison between simulation results and experimental ones, the validity of design process is verified.
