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.

A magnetically levitated transport system comprising:
- a linearly extensive stator, engaged with a linear rotor, the rotor adapted for moving along the stator axially by electromotive forces;
- the stator and the rotor each having a triangular shape with the stator positioned within the rotor and separated therefrom by a gap on three sides;
- a plurality of spaced apart first sets of gap maintaining electromagnets engaged with the stator, the first sets axially spaced apart;
- a plurality of spaced apart second sets of gap maintaining electromagnets engaged with the rotor, the second sets axially spaced apart in correspondance with the first sets;
- the rotor positionable along the stator to bring the first sets and second sets of gap maintaining electromagnets into respective mutual proximity, thereby enabling magnetic repulsive forces between the sets of gap maintaining electromagnets to maintain said gap against gravitational and inertial forces on the rotor;
- a plurality of spaced apart triangular sets of traction coils positioned on three sides of the stator;
- a plurality of spaced apart triangular sets of traction electromagnets positioned on three sides of the rotor;
- the rotor positionable along the stator to bring the sets of traction coils and the sets of traction electromagnets into respective mutual proximity, thereby enabling electromagnetic thrust forces between the sets of traction coils and traction electromagnets to move the rotor along the stator.
