ABSTRACT:
A magnetically levitated transport system moves a suspended cargo such as passengers and freight. A linear motor uses a track stator about which a “rotor” moves linearly. Stator and rotor circuits interact electromagnetically to maintain a gap between the moving and fixed elements. Tractor coils are embedded within the track to produce thrust through electromotor action with magnets aboard the rotor. The rotor is configured in a triangular shape as is the track with opposing electromagnets positioned for creating mutual repulsion forces. A pulsed direct current in the stator circuit, derived from conventional alternating current taken from the power grid, is used to create an induced current in the rotor, which, in turn is used to energize rotor electromagnets.
