Rotary disk energy storage and pulse power supply

A system for powering an electrical load, said system comprising:

• a base;
• a pair of rotors positioned on the base for rotation about an axis, with each rotor having a first plurality of permanent magnets mounted thereon at a first radial distance from the axis, and a second plurality of permanent magnets mounted thereon at a second radial distance from the axis to establish a radial gap between the first plurality of permanent magnets and the second plurality of permanent magnets;
• a stator mounted on the base to extend between the rotors;
• an electrical means mounted on the stator for interacting with the first pluralities of permanent magnets to rotate the pair of rotors and their respective second plurality of permanent magnets to generate a time-varying magnetic field;
• a winding mounted on the stator to generate a current in response to a rotation of the second pluralities of permanent magnets;
• a means for connecting the winding to the electrical load to provide current from the winding for the electrical load;
• and
• a conductive shield mounted on each rotor for rotation therewith, said conductive shield being positioned between said second plurality of permanent magnets and the winding on said stator to prevent de-magnetization of said second plurality of permanent magnets when said switch is closed, wherein said conductive shield terminates adjacent the radial gap between the first plurality of permanent magnets and the second plurality of permanent magnets.

A method for powering an electrical load, said method comprising the steps of:

• mounting a pair of rotors for rotation on a base, with each rotor having a first plurality of permanent magnets mounted thereon and a second plurality of permanent magnets mounted thereon to establish a radial a between the first plurality of permanent magnets and the second plurality of permanent magnets, with a stator fixedly mounted on the base and extending between the rotors, wherein the stator includes a polyphase winding for interacting with the first pluralities of permanent magnets, and a winding for interacting with the second pluralities of permanent magnets;
• energizing the polyphase winding to generate a time-varying magnetic field with the second plurality of permanent magnets and a consequent current in the winding in response to rotation of the second plurality of permanent magnets;
• selectively connecting the winding to the electrical load to provide current from the winding for the electrical load;
• and
• providing a conductive shield mounted on each rotor for rotation therewith, each conductive shield being positioned between respective said second plurality of permanent magnets and the respective winding on said stator to prevent de-magnetization of said second plurality of permanent magnets when said switch is closed during a connection of the winding with the electrical load, wherein each conductive shield terminates adjacent the radial gap between the respective first plurality of permanent magnets and the respective second plurality of permanent magnets.
