Polyphasic multi-coil generator
First Claim
1. A method of operating a generator, said generator comprising:
- a driveshaft;
a first rotor rotatable by said driveshaft, said first rotor having a first array of magnets mounted thereon;
a first stator having a first plurality of electrically conductive coils mounted thereon, wherein rotation of said first rotor relative to said first stator induces a current in at least some of said electrically conductive coils;
said method comprising controlling an output voltage of said generator by dynamically modifying an electrical connection between coils of said first plurality of electrically conductive coils;
wherein said first plurality of electrically conductive coils are grouped into a plurality of stages, each stage comprising at least one electrically conductive coil, wherein rotational resistance for rotating said driveshaft increases when each stage is electrically energized from an open to a closed circuit, said method further comprising selectively electrically energizing each of said stages to increase the rotational resistance for rotating said driveshaft when said driveshaft rotates at a predetermined rotational speed.

Abstract
A polyphasic multi-coil generator includes a driveshaft, at least first and second rotors rigidly mounted on the driveshaft so as to simultaneously synchronously rotate with rotation of the driveshaft, and at least one stator sandwiched between the first and second rotors. The stator has an aperture through which the driveshaft is rotatably journalled. A stator array on the stator has an equally circumferentially spaced-apart array of electrically conductive coils mounted to the stator in a first angular orientation about the driveshaft. The rotors and the stator lie in substantially parallel planes. The first and second rotors have, respectively, first and second rotor arrays.
