There is a levitation method which uses 8-shape levitation coils arranged on the vertical surface of the guideway. These coils can act as a guidance means as well as the levitation means. The characteristics of this system is examined using numerical examples and experimental data. The cables connecting right and left coils are not connected to a high voltage power source unlike the usual guidance system which is combined with propulsion. Thus the electric insulation of the cables is now not a problem. Numerical examples show that the levitation characteristics of the combined levitation and guidance system is almost the same as in the system without the guidance function, and that it atains reduced running resistance with necessary guidance stiffness obtained. Test run was done at Miyazaki Test Line equipped with coils of this type arranged about 120m, and the results show stable running and balanced displacement which agrees with calculated value.
