Based on the decoupled-control method of attractive-normal and thrust forces, a compact cotnbined-levitation-and-propulsion single-sided linear induction motor (SLTM) maglev vehicle system can be realized without any additional levitation magnets. In this paper, we have proposed a mass-reduced mode control of the SLIM vehicle based on its decoupled-control method and succeeded in a stable propulsion control experiment in 95%-mass-reduced mode at a minimum airgap-length of 1.7 mm limited by guide-rollers even by using a simple construction of wheel and rail system without primary suspension. The vehicle has been propelled with the minimum power for supporting the vehicle by realizing simidtaneously the minimum airgap and the soft-touch, so that it has been driven with small noises and vibrations because of very soft contact. And considering the wear and the maintenance, this running method with soft-touch mass-reduced control is very useful for many practical applications.
