무가선 트램용 추진 유도전동기 설계 및 특성 고찰

The latest generation of tram is low-floor design, various nations in europe and japan have developed battery driven hybrid trams that combine battery and wiring. Battery driven tram system is achieved by contact-less power supply system, thus system is needed high efficiency, high power and low weight traction motor for maximization of energy efficiency. Research from abroad is still in induction motor(IM) application, but, the research of determinations of loading condition and design point is not enough to design induction motor for railway vehicle traction. In this paper, considerations of induction motor design and characteristics are studied for railway vehicle traction.
