The authors have developed a new electromagnetic levitation system, which eliminates power collecting devices from a magnetically levitated vehicle. This system makes it possible to transport materials without any mechanical contact between the vehicle and ground facilities. This paper describes a control system for linear induction motors used in the magnetically levitated carrier system. The system was developed to transport materials in an environment which must be kept free from even microscopic dust motes and trivial noise. It is one of the applications which make the most of the newly developed electromagnetic levitation system. The linear induction motor control method for positioning a vehicle at the station, and several kinds of switches without any mechanical motion in the ground facilities, are introduced. Furthermore, a supervisory control system for the magnetically levitated carrier system is also introduced.
