Abstract

Motor, either synchronous or direct current, including at least one drive coil and including a magnetic rotor having at least two concentric rings of magnetic domains of alternating magnetic poles, with each succeeding rotor ring being of a larger diameter than the previous rotor ring. The drive coil is radially movable so as to be positioned over or adjacent to each of the rotor rings.

Claims

1. Motor including a concentric ring rotor for use in a vehicle or other like mechanical, electrical or electromechanical structure, comprising:

a. a rotor support axially and rotatably mounted on a first shaft, said first shaft secured to a frame means;

b. a plurality of concentric ring rotors increasing from a smaller diameter to a larger diameter, a rotor support plate supporting each of said rotors, said plurality of rotors aligned on and stacked on said first shaft;

c. a plurality of magnetic domains of alternating magnetic poles on each of said concentric ring rotors in increasing diameters, said plurality of magnetic domains including a plurality of members of magnetic material;

d. a means for braking each of said concentric ring rotors including a braking coil and a load means connected to each of said braking means and a linkage means including a one-bar pivotal linkage on a second shaft axially positioning said braking means over and adjacent to at least one of said concentric ring rotors about an arcuate position of said second shaft; and

,

e. a plurality of drive coil means axially aligned and mounted on a third shaft means including a one-bar pivotal linkage on said third shaft for arcuate rotation over and adjacent to each of said concentric rotor rings, said second and third shafts secured to said frame means whereby said drive coils are arcuately positioned over and adjacent to each of said concentric rotor rings thereby driving said concentric ring rotors on said shaft.

2. The motor of claim 1 comprising an energy storage means connected to said braking means for storing substantially all of said energy during braking in said energy storage means.

3. The motor of claim 1 wherein said energy storage means comprises a storage battery.

4. The motor of claim 1 wherein said drive coil means is synchronous.

5. The motor of claim 5 wherein said synchronous drive coil means connects to a source of alternating current power.

6. The motor of claim 5 wherein said synchronous drive coil means connects to said alternating current power source through a diode.

7. The motor of claim 5 wherein said synchronous drive coil means connects to a source of pulsed direct current power.

8. The motor of claim 5 wherein said drive coil means connects to a source of direct current power.
