ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to linear electric machines, capable of converting electrical current into mechanical work or mechanical work into electrical current. More specifically, this invention relates to an electric machine having a ferromagnetic vessel containing a single-pole magnetic field, end caps for reflecting magnetic energy and a shaft having an electromagnetic coil which moves relative to the magnetic field.
Electric machines have been known in the art for decades. Motors, which generate mechanical energy from electric current, use the ability to create repulsive and/or attractive magnetic forces through the use of electromagnets to create movement. Generators, which create electrical current from mechanical energy function on the long known principle that movement of a wire loop through a magnetic field produces an electric current.
Typically these electric machines require electromagnetic windings to move in and out of different magnetic fields in order to function. It is heretofore unknown in the art to design an electric machine where the electromagnetic windings are able to move solely within a single-pole magnetic field.
Additionally, despite the fact that movement of electric wires through magnetic fields is known to generate electric current, and electric motors have electric wires which move through magnetic fields, the ability to design an electric motor which, during at least some portions of its cycle can generate at least some of the current necessary to drive the motor is unknown. A motor which could generate a portion of the electric current necessary to drive it would be significantly more energy efficient than a conventional motor where such internal generation is not possible and would be a significant advancement in the art.
SUMMARY AND OBJECTS OF THE INVENTION
The present invention involves a linear electric machine, whether motor or generator. This machine creates a single-pole magnetic field within a ferromagnetic vessel. The single-pole magnetic field can be created either by permanent, typically radially-poled, magnets or electromagnets and the ferromagnetic vessel can contain any material capable of reflecting the magnetic energy from the magnets into the vessel. This arrangement of the magnets, all with the same pole oriented within the vessel, creates a region of concentrated magnetic energy within the field, typically at or around the center of the magnets. In other words, where the single-pole magnetic field is a south pole field, a concentrated region of south pole magnetic energy exists, typically at or around the center of the magnets, within the south pole field.
Inside the single-pole magnetic field is positioned a shaft with an attached electromagnetic coil, the top and bottom of which are on opposite sides of the concentrated magnetic energy region. The configuration of the windings within the coil can also be optimized to further optimize the forces between the single-pole magnetic field and the coil. End plates, either attached to the coil or to the vessel further reflect the magnetic energy within the vessel.
When functioning as a motor, electric current is introduced into the coil of the shaft creating an electromagnet in the coil with the top and bottom of the coil containing the north and south poles. Since the top and bottom of the coil are on opposite sides of the concentrated magnetic energy region of the field, the opposite forces created by repulsion of the coil's like pole and attraction of the coil's opposite pole to the concentrated magnetic energy within the field produces linear force to move the coil and shaft relative to the magnetic field. As the coil, with its electromagnetic windings, moves through the electromagnetic field the movement of those electromagnetic windings through the field creates electric current generation, thereby reducing the quantity of electrical energy or current required to maintain the electromagnet in the coil and movement of the shaft.
As the top, or bottom depending on the shaft's direction, approaches the region of concentrated magnetic energy within the field, the direction or polarity of the current within the windings of coil is reversed thereby reversing the north and south poles in the coil and reversing the forces on and direction of the shaft. Repetition of the cycle and maintenance of the shaft and coil within the field creates a motor whose electrical consumption necessary for creation of mechanical energy is considerably less than that of standard electric motors.
When functioning as a generator, mechanical energy moves the shaft and coil relative to the field while maintaining the shaft and coil within the field in a reciprocating cycle identical to that described above with the motor. This movement of the electromagnetic windings of the coil through the magnetic field creates electric current, and like the motor, can accomplish the conversion of mechanical energy to electrical energy more efficiently than in conventional generators.
Accordingly, an object of the present invention is to create an electric machine capable of more efficiently producing both mechanical energy from electric energy and electric energy from mechanical energy.
Another object of the present invention is to create an electric machine which has a region of concentrated magnetic energy within a single-pole magnetic field capable of interacting with an electromagnetic coil.
It is yet another object of the present invention to create an electric machine where the moving parts stay within a single-pole magnetic field.
It is yet another object of the present invention to create winding configurations in electromagnetic coils moving within a single-pole magnetic field which can optimize the magnetic forces between the electromagnetic coil and the single-pole magnetic field.
These advantages in addition to other objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.
