Abstract
An electomotive mechanism is provided including a stator assembly and rotor assembly. The stator assembly is provided with a plurality of stator rings, defining an annular aperture therebetween. A rotor assembly is disposable within the annular aperture and rotatable therebetween. In the preferred embodiment the stator assembly includes a wound stator and the rotor assembly includes a wound rotor.
Claims
1. (Amended) An electromotive mechanism comprising:
(a) a stator assembly having the plurality of radially spaced stator rings defining an annular aperture therebetween; and
(b) a rotor assembly disposable within the annular aperture and rotatable therein.
2. The mechanism as recited in Claim 1 further comprising a stator coil (s ) formed upon each of the stator rings , and a rotor coil(s) formed upon the rotor.
3. The mechanism as recited in Claim 2 wherein the stator coil(s) and rotor coil(s) are disposable in corresponding space opposed annular segments, wherein the rotor coil annular segment (s) is rotatable with respect to the stator coil annular segment (s).
4. The mechanism as recited in Claim 3 wherein the rotor coil annular segment (s) and the stator coil annular segment (s) are excitable to generate a rotational force applied to the rotor, the rotational force being operative to rotate the rotor with respect to the stator.
5. The mechanism as recited in Claim 4 further comprising a switching circuit for regulating excitement of the stator coil(s) and rotor coil(s) to affect variable speed rotation of the rotor.
6. The mechanism as recited in Claim 5 wherein the dominant rotational force applied to the rotor remains substantially in the same direction when the switching circuit excitement outruns rotor rotational speed.
7. The mechanism as recited in Claim 5 wherein the dominant rotational force moving substantially in the same direction when the rotor rotational speed outruns the switching circuit excitement.
8. The mechanism as recited in Claim 1 wherein rotor rotational position is asynchronous with respect to coil excitement timing.
9. The mechanism recited in Claim 5 wherein rotor rotational speed is asynchronous with respect to coil excitement rate.
10. (Amended) The mechanism as recited in Claim 2 wherein the stator is a coreless wired stator.
11. (Amended) The mechanism as recited in Claim 9 wherein the rotor is a coreless wired rotor.
12. The mechanism as recited in Claim 1 further comprising a stator support member formed of insulating material, wherein at least a portion of the stator coil is encapsulated, the insulating material forming the stator support member.
13. The mechanism as recited in Claim 2 wherein the stator coil(s) and the rotor coil (s) operate to radiate a coaxial flux pattern (s) therebetween.
14. The mechanism recited in Claim 2 wherein the stator coil(s) comprises a plurality of axially spaced stator coils.
15. The mechanism recited in Claim 2 wherein the rotor coil(s) comprises a plurality of axially spaced rotor coils .
16. The mechanism as recited in Claim 2 further comprising a conductive cylindrical return member disposed in abutting contact with the stator assembly, the return member being stationary relative to the stator assembly and
