Abstract

A motor includes a number of individual electric coils arranged in the shape of a toroid around a ferromagnetic core, and configured so that, upon the application of electric current through the plurality of individual coils, the stator generates a rotating magnetic field within the ferromagnetic core. The motor also includes a magnetic rotor having a number of individual magnets positioned on the rotor such that adjacent magnets alternate in magnetic orientation, and are configured to direct magnetic flux lines through the stator. Further, the motor includes a controller configured for controlling the distribution of electric current to said plurality of individual electric coils. A generator may be similarly constructed, where the rotor is mechanically rotated to induce an electric current through the individual electric coils.

Claims

1. A motor comprising:

a plurality of individual electric coils arranged in the shape of a toroid and configured so that, upon the application of electric current through the plurality of individual coils, adjacent individual coils generate magnetic fields of opposing polarities;

a stator fabricated from ferromagnetic material positioned within the plurality of electric coils;

a magnetic rotor including a plurality of individual magnets positioned on the rotor

such that adjacent magnets alternate in magnetic orientation, said magnets configured to direct magnetic flux lines through said stator; and

a controller configured for controlling the distribution of electric current to said plurality of individual electric coils.

2. The motor of claim 1, wherein said controller distributes electric current to said plurality of individual electric coils in a rolling biphasic configuration, said individual coils configured as groups comprising two or more adjacent coils, said adjacent coils connected in series such that said coil groups provide a virtual coil such that as said rotor spins, said controller selectively reconfigures and energizes each coil group so as to continuously urge rotation of said rotor.

3. The motor of claim 1, further comprising a sensor, wherein said sensor is positioned to determine the location of said rotor in relation to said plurality of electric individual coils, wherein said sensor is configured to communicate said position of said rotor to said controller.

4. The motor of claim 1, wherein said rotor includes a drive shaft.

5. The motor of claim 1, wherein said controller is configured to conduct three phase alternating electric current.

6. The motor of claim 1, further comprising an induction cylinder coaxial with the magnetic rotor and having a circumference smaller than an internal circumference of the magnetic rotor, or larger than an external circumference of the magnetic rotor, the induction cylinder disposed adjacent the magnetic rotor and positioned for relative rotation through magnetic flux lines emanating from the magnetic rotor.

7. The motor of claim 6, further comprising an actuator configured to move the induction cylinder relative to the magnetic rotor.

8. The motor of claim 6, in which the induction cylinder is coupled to a means of mechanical torque transfer that has an axis of rotation through the center of the magnetic rotor.

9. The motor of claim 6, in which the induction cylinder is a metal cylinder.

10. A generator comprising:

an armature comprising a plurality of individual electric coils arranged in the shape of a toroid, said armature further comprising a core fabricated from ferromagnetic material positioned within the plurality of individual electric coils;

a magnetic rotor including a plurality of individual magnets positioned on the rotor such that adjacent magnets alternate in magnetic orientation, said magnets configured to direct magnetic flux lines through said stator, said rotor configured to receive mechanical torque so that upon receipt of said torque the rotation of said rotor causes a rotating magnetic field to pass through said armature; and

a controller configured to direct electric current from said plurality of electric coils to a load.
