A study on the design and characteristic analysis of LIM for the deep-underground GTX propulsion system

In order to develop the deep-underground GTX in Korea, the specification decision and development of the traction control system (including inverter and traction motor), which consider a variety of route condition, must be advanced. Therefore, authors study the running resistance properties of a high-speed traction system by the variety of the tunnel type and the vehicle organization method at first. Next, authors study the properties of the power requirement of the traction motors that is necessary to maintain the balanced speed of the high-speed traction system. Then, authors present the element techniques including the design specification for a development of the high-speed traction system for the deep-underground GTX. Finally, authors design a LIM for a propulsion system and analyze its performance by using FEM when the LIM propulsion system travels within the deep-underground tunnel.
