Magnetically lifted vehicles using hover engines
Electromechanical systems using magnetic fields to induce eddy currents and generate lift are described. Magnet configurations which can be employed in the systems are illustrated. The magnet configuration can be used to generate lift and/or thrust. Arrangements of hover engines, which can employ the magnet configurations, are described. Further, vehicles, which employ the hover engines and associated hover engines are described.
1. A vehicle comprising:
a first hover engine, a second hover engine, a third hover engine and a fourth hover engine, each of the first hover engine, the second hover, the third hover engine and the fourth hover engine having,
an electric motor including a winding, a first set of permanent magnets and a first structure which holds the first permanent magnets wherein an electric current is applied to the winding to cause one of the winding or the first set of permanent magnets to rotate;
a second structure, configured to receive a rotational torque from the electric motor to rotate the second structure,
the second structure holding a second set of permanent magnets wherein the second set of permanent magnets are rotated to induce eddy currents in a substrate such that the induced eddy currents and the second set of permanent magnets interact to generate forces which cause the vehicle to hover above and/or translate from location to location along the substrate;
one or more speed controllers coupled to the first hover engine, the second hover engine, the third hover engine and the fourth hover engine;
an on-board electric power source that supplies the electric current to the first hover engine, the second hover engine, the third hover engine and the fourth hover engine via the one or more speed controllers;

a first hinge mechanism, near the front end and beneath the rider platform, which is coupled to the rider platform, the first hover engine and the second hover engine, wherein the first hinge mechanism is configured to rotate the first hover engine and the second hover engine in a first direction, during flight, when a force is applied on a first portion of the upper surface, and in a second direction, opposite the first direction, when the force is applied on a second portion of the upper surface;
a second hinge mechanism, near the back end and beneath the rider platform and coupled to the rider platform, the third hover engine and the fourth hover engine, wherein the second hinge mechanism is configured to rotate the third hover engine and the fourth hover engine in the first direction, during flight, when the force is applied on a third portion of the upper surface, and in the second direction, when the force is applied on a fourth portion of the upper surface;
where in the first hover engine, the second hover engine, the third hover engine and the fourth hover engine are each secured to the vehicle at a fixed angle such that each of the first hover engine, the second hover engine, the third hover engine and the fourth hover engine output a translational force, when the vehicle is in a first orientation during flight, and wherein the translational forces from each of first hover engine, second hover engine, the third hover engine and the fourth hover engine approximately cancel one another to provide a net translational force which is approximately zero.

9. The vehicle of claim 8 , wherein one or more electronic speed controllers are configured to receive, via the wireless transceiver, a command from the remote device to shut down the first hover engine, the second hover engine, the third hover engine and the fourth hover engine and in response to the command, shutdown each of the hover engines.
10. The vehicle of claim 1 , further comprising four electronic speed controllers, each of the electronic speed controllers configured to be coupled to one of the first hover engine, the second hover engine, the third hover engine and the fourth engine.
11. The vehicle of claim 10 , wherein each of the electronic speed controllers is mounted above one of the hover engines.
12. The vehicle of claim 1 , further comprising a mounting plate including a first portion and a second portion wherein a first electric motor associated with the first hover engine is mechanically coupled to the first portion such that it is suspended beneath the first portion and such that the first portion forms a top part of an enclosure which surrounds the first electric motor and wherein the second portion is secured to the first hinge mechanism such that the mounting plate and the first hover engine are secured beneath the first hinge mechanism.
13. The vehicle of claim 1 , wherein the rider platform includes a first side and a second side along a length of the rider platform between the front end and the back end and wherein, when the force is applied in a fifth portion on the upper surface near the first side, both the first hinge mechanism and the second hinge mechanism rotate in opposite directions to cause the vehicle to translate sideways in a direction from the second side to the first side.
