ABSTRACT:
A magnetic levitating transportation apparatus including rails and a vehicle capable of travelling along the rails by a linear motor and caused to magnetically levitate by magnet units with electro-magnets. The gap is controlled by controlling the current supplied to the magnet units in response to gap sensors. The rails include rail gaps where the ends of two rail elements abut, and rail gap sensors are arranged to detect the rail gap. Thus, current supplied to one of the magnet units is disabled when the rail gap is detected, and the current to be supplied to the associated magnet unit is stopped. The current to be supplied to the associated magnet unit is determined from the outputs of the remaining gap sensors.
