In commercializing the superconducting maglev system it is important to reduce the cost, especially that of ground coils constructed along the whole length of the guideway. For this purpose we have examined the combined propulsion, levitation and guidance system. (PLG system) This system can generate levitation, guidance and propulsion forces by the same ground coils. Therefore this system is expected to save the cost of ground coils, number of which are decreased. In this paper we present the principle and analytical formula of the PLG system. In addition, using numerical examples, and running test at the Miyazaki test track, the characteristics of this system are expressed.
