A Study on Traction Motor Running Characteristic in Conventional Line

초록

Railways have merits in terms of safety, large-volume transportation, high speed, energy saving, riding comfort, and environment protection, becoming the preferred public transportation around the world. Being the most favored transportation means recently, electric railroad plays its unique role as a mass transportation. In countries like France, Germany, and Japan, research on high-speed, lightweight, and energy-saving electric train is being carried out in fierce competition. The experiment TTX (Tilting Train eXpress) EMU for conventional railroad being developed as a part of the Railroad Technology Research Development project consists of 2-units made up of 6 cars. Each unit consisting of 3 cars has an independent motor traction system. The basic operating train consisting of 2 operating units/6 cars can be extended to 3 units/9 cars or 4 units/12 cars. Figure 1 shows apperance of TTX. A unit consisting of 3 cars, that is 2 motor cars and 1 trailer, in 2M1T structure is the advanced EMU system configuration widely used today. Figure 2 is the diagram of the experiment train system configuration. The Mcp car has motor, car control, and pantograph
