초록

본 논문에서는 철도차량 추진용 매입형 영구자석 동기전동기(Interior Permanent Magnet Synchronous Motor, IPMSM)의 운전 중 열 발생 특성 분석을 위한 열해석 기법 연구를 수행하였다. IPMSM의 구동 중에 권선, 코어, 영구자석에서 발생되는 과도한 열은 IPMSM의 장시간 연속운전을 어렵게 만들기 때문에, IPMSM에서 발생된 열의 효율적인 냉각이 중요하다. 따라서 본 연구에서는 IPMSM의 냉각장치 적용을 위한 선행 연구로써 IPMSM 의 열 발생 특성 분석을 위하여 IPMSM의 각 구성품에 대한 열전달 계수를 도출하고, 열 등가회로를 구성하여 열해석을 수행하는 열해석 기법 연구를 수행하였다. 또한 IPMSM 실 모델의 열 실험 데이터와의 비교를 통한 열해석 기법의 유효성 검증을 수행하였다.

In this paper, research on the thermal analysis method is reported for the characterization of heat generation while operating an Interior Permanent Magnet Synchronous Motor (IPMSM) for railway vehicles. Efficient cooling of the heat generated in the IPMSM is important because the excessive heat generated from the winding, core and permanent magnets increases the difficulty of continuously operating an IPMSM over long time periods. Therefore, in this study, in order to analyze the heat generation characteristics of the IPMSM for advanced research in the application of IPMSMs to cooling devices, the heat transfer coefficients for each component of the IPMSM were derived and the thermal equivalent circuit was configured to perform thermal analyses. Finally, the validation of the suggested thermal analysis method was performed through comparison with the heat experimental data of an IPMSM prototype.
