고속철도차량 유도전동기를 제어하는 1C1M 구조의 추진제어장치 개발 및 성능 시험

Motor Block (MB) applied to KTX-SANCHEON is 1C2M structure. Since controlling two motors at the same time, 1C2M structure loses the power of 25% per a Train (10 cars) when a MB is failure and strict management is needed between the diameter of the wheels on the same bogie. In this paper, we describe the 1C1M MB applied to the high speed rolling stock equipped with induction motors. Since a MB control a motor, 1C1M structure loses the power of 12.5% per a Train. So 1C1M MB is high availability compared to 1C2M MB and less strict management is needed between the diameter of the wheels on the same bogie. In this paper, we describe the composition, the structure and test result of 1C1M MB.
