철도차량에 이용되는 고효율 3상 유도전동기 설계연구 개발

In today, the energy saving in existing electrical machines used a variety of facilities is very important because the energy shortage becomes a serious social problem. Especially, electrical machines occupy a large percentage of consuming electrical energy and the three phase induction motor used in a railroad system also consume a lot of electrical energy. Therefore the design of high efficiency three phase induction motor for railroad is a essential method to satisfy aspects of enhancing performance of railroad and energy saving in railroad system. The main contents in this paper are the fundamental process of design of high efficiency three phase induction motor and selecting some design parameters to be considered in each step. The results of designed motor is analyzed by using the FEM.
