ABSTRACT:
A system for magnetically supporting a vehicle equipped with permanent magnets and propelled by a linear induction motor along a roadway defined by a stator member energized by polyphase alternating current, the system including members located on the vehicle for maintaining the air-gap between the pole faces of the permanent magnets and the stator member. In a preferred form the air-gap maintaining members are electro-magnets whose energizing windings are supplied with variable current to effect the control of the air-gap distance.
