Abstract (en)
To provide a door opening and closing apparatus for an electric train which facilitates smooth driving of the door without overstraining the door and eliminates cumbersome fine tuning, a linear motor (14), comprised of stator coils (2) and a moving field means (3), is mounted in a frame (1); and the moving field means (3) is slid along the stator coils (2) by controlling current flow through the linear motor (14); and a door (6) coupled with the moving field means (3) is smoothly driven. An emergency power supply (12) is provided to allow opening of the door (6) in the event of a power failure. <IMAGE>
