Abstract

Many types of door system are used in the Electric Multiple Unit (EMU). The door system is categorized to the two types of door system, sliding door and plug door. The sliding door is widely used in the EMU but has weak point for the noise problem. The plug door has advantages for the noise reduction characteristic. Nowaday electric door system is widely used and motor is a main part of driving system in the door system. We have to know the exact driving position of door system to control proper operation of the door. Actually encoder or tachometer is used for the position controlling, but it makes price increase and failure increase. In this paper, we study and describe motor current calculation method to contol and know exact driving position of door system.
