Abstract
Pairs of unidirectionally magnetic rotor/stator assemblies are mounted for synchronous rotation and complementary, so that one creates pulsating positive current flow and the other creates pulsating negative current flow, as the rotor and stator in each assembly are rotated with respect to each other. The pulsating positive current flow and pulsating negative current flow are combined at a desired phase angle to create alternating current, without power loss due to reversal of current flow.
Claims13
A generator, comprising:
- a pair of complementary stator/rotor assemblies;
- wherein said stator and rotor assemblies are mounted for synchronous rotation;
- wherein each of said stator and rotor assemblies comprises:
- a stator;
- coils mounted on said stator in a stator ring region;
- a rotor;
- magnets having magnetic fields with north and south poles mounted on said rotor in a rotor ring region having a shape and size substantially identical to said stator ring region, with all said north poles oriented outward from a north face of said rotor and all said south poles oriented outward from a south face of said rotor;
- wherein said rotor is mounted for rotation around an axis of rotation centered in, and perpendicular to, said stator ring region;
- wherein said rotor is parallel to, and closely displaced from, said stator by a rotor/stator gap;
- whereby said magnetic fields of said magnets are axially aligned with said axis of rotation;
- and
- whereby said magnets overlay said coils, separated by said rotor/stator gap;
- whereby rotation of said rotor around said axis of rotation causes said poles of said magnets to travel towards and away from said coils to induce a pulsating current flow in only one direction through said coils;
- wherein said stator and rotor assemblies are separated from each other by a separation distance sufficiently great to avoid substantial drag from interaction of their magnetic fields;
- wherein said coils and magnets of a first of said pair of stator and rotor assemblies are configured to be complementary to said coils and magnets of the second of said pair of stator and rotor assemblies, so the first of said pair creates pulsating current in only one direction, and the second of said pair creates pulsating current in the opposite direction, and said coils are wired and wound so that said pulsating currents are combined at a desired phase angle to create alternating current;
- whereby power loss from reversal of current flow is avoided.

- a second rotor parallel to said second stator, mounted for rotation around a second rotor axis of rotation, closely displaced from said second stator by a second rotor/stator gap;
- a plurality of blades drivably connected to said first rotor and said second rotor;
- whereby when said blades rotate, said blades drive said first rotor and said second rotor to synchronous rotation;
- wherein said first stator and said first rotor comprise a first stator and rotor assembly and said second stator and said second rotor comprise a second stator and rotor assembly;
- wherein each of said stator and rotor assemblies comprises:
- coils mounted on said stator in a stator ring region concentric with said rotor axis of rotation;

- whereby said magnetic fields of said magnets are axially aligned with said rotor axis of rotation;
- and
- whereby said magnets overlay said coils, separated by said rotor/stator gap;
- whereby rotation of said rotors around said rotor axes of rotation causes said poles of said magnets to travel towards and away from said coils to induce a pulsating current flow in only one direction through said coils;
- wherein said coils and magnets of said first stator and rotor assembly are configured to be complementary to said coils and magnets of said second stator and rotor assembly, so the first stator and rotor assembly induces a pulsating current in only one direction and the second stator and rotor creates a pulsating current flow in only the opposite direction, whereby the pulsating current flows from both stator and rotor assemblies can be combined to create alternating current;
- wherein said stator and rotor assemblies are separated from each other by a separation distance sufficiently great to avoid substantial drag from interaction of their magnetic fields;
- whereby power loss from reversal of current flow is avoided.
