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 특성분석을 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 thermal analysis method is conducted for the characterization of heat generation during operation of 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 magnet makes it harder for a long time continuous operation of IPMSM. Therefore, in order to analyze the heat generation characteristics of the IPMSM as advanced research for application the IPMSM to the cooling device, the heat transfer coefficients for each component of the IPMSM were derived and the thermal equivalent circuit was configured to perform the thermal analysis in this study. Finally, the validation of the suggested thermal analysis method was performed through the comparison with the heat experimental data of IPMSM prototype.

Traction motors for driving and power conversion devices using semiconductor switch are equipped with a transportation systems such as an electrical railway system. Power conversion devices have the possibility of malfunction by external electromagnetic waves. As a result, these could affect the safe operation of the railway. Moreover, the electromagnetic waves above safe limits will be harmful to the passengers inside the railway vehicles or anyone working around the rail-track. For this reason, the importance and need about the reliability check and complement of electromagnetic waves generated from the IPT(Inductive Power Transfer) system have been suggested for the safe application of the IPT system to the railway system. In this study, prediction for the electromagnetic wave properties was conducted through FEM(Finite Element Method) analysis of 5kW-class IPT system design model. Next, the 5kW IPT system prototype was made and then the small-scaled railway vehicle was made to mount the IPT system and the energy management system. Finally, the electromagnetic waves generated from the real small-scaled IPT system were measured and analyzed, and then the reliability check of predictions by FEM analysis were carried out.

Inductive power transfer module(IPTM) is a contact-less power supply device and its application range has been extended to the large capacity devices such as electric vehicles, industrial mover and railway system as well as small capacity devices such as electric toothbrush charger, celluar phone charger, and so on. For railway application, the IPTM will transfer energy while train stops at a station for around 30[sec]. Therefore, equivalent circuit parameters and coupling coefficient of IPTM are an important design factor for the high energy transfer efficiency. This paper investigates the properties of equivalent circuit parameters and coupling coefficient of U-U type IPTM and U-I type IPTM using an analytical method and experimental method. Considering the coupling coefficient of the U-U type is larger than U-I type’s, the U-U type is suitable for an application which need maximum power transfer and high efficiency.

휠-레일 방식 초고속열차용 초전도 선형동기전동기의 지상권선 방식별 특성 분석
박찬배(Chan-Bae Park),이병송(Byung-Song Lee),이창영(Chang-Young Lee) 대한전기학회 2014 전기학회논문지 Vol.63 No.8
Recently, an interest in a hybrid system combining only the merits of the conventional wheel-rail system and Maglev propulsion system is growing as an alternative to high-speed maglev train. This hybrid-type system is based on wheel-rail method, but it enables to overcome the speed limitation by adhesion because it is operated by a non-contact method using a linear motor as a propulsion system and reduce the overall construction costs by its compatibility with the conventional railway systems. Therefore, the design and characteristic analysis of a coreless-type superconducting Linear Synchronous Motor (LSM) for 600km/h very high speed railway system are conducted in this paper. The designed coreless-type superconducting LSMs are the distributed winding model, the concentrated 1 layer winding model and the concentrated 2 layer winding model, respectively. In addition, the characteristic comparison studies on each LSM are conducted.
