MAGNETICALLY LEVITATED TRANSPORTATION APPARATUS

摘要

The present disclosure relates to a magnetically levitated transportation apparatus. In order to effectively transfer a heavy transfer body such as a large-area display panel, the magnetically levitated transportation apparatus includes one or more levitation electromagnets disposed at an upper part of a chamber along a movement direction of a transfer tray to provide a magnetic force for levitating the transfer tray, one or more first ferromagnetic cores disposed on the transfer tray so as to be opposite to the levitation electromagnet, levitating the transfer tray by an attractive action with the magnetic force of the levitation electromagnet, one or more stator coils disposed on at least one surface of an inner side of the chamber along the movement direction of the transfer tray to provide a magnetic force for moving the transfer tray in a horizontal direction, one or more mover propulsion modules disposed on at least one surface of the transfer tray along the movement direction of the transfer tray to provide a horizontal propulsive force to the transfer tray through an attractive or repulsive action with the magnetic force provided by the stator coil, and one or more mover guidance modules disposed along a disposition direction of the mover propulsion module to control a gap between the transfer tray and the chamber by an attractive or repulsive action with the stator coil.
