Many magnetically levitated systems are applied in semiconductor factories to avoid the dusts. The proposed magnetically levitated system in this paper consists of a linear induction motor (LIM) as a guide way and a vehicle. The system is a kind of attraction type levitation system by alternating current. Both the driving force and the levitation force are obtained by the magnetic force of LIM. In this paper, the levitation characteristics at three phase excitation and at equivalent slipping state are discussed experimentally. The results show that the vehicle can be levitated without any contact to the guide way. Moreover, as a prototype vehicle model, the vehicle with a storage battery and charging circuit is proposed. The battery can be charged by the transformer effect of secondary winding. As a result, it is clarified that the vehicle can be levitated stably even in the charging state. Finally the change of levitation characteristics by horizontal displacement is discussed with looking into the affect of slots.
