Abstract
A positioner has a first surface with a plurality of controlled electromagnets and a second surface having a circular cross-section movably positioned relative to the first surface. A plurality of magnetic positioners are disposed around the second surface. Control logic energizes a sequence of the controlled electromagnets to create magnetic interaction with the plurality of magnetic positioner and thereby move the second surface relative to the first surface. A rotor may be positioned to rotate relative to the second surface. Electromagnetic pickups in proximity with the rotor receive a time-varying electromagnetic field from rotor magnets as the rotor rotates, thereby generating electrical energy.
Claims6
A magnetic system comprising:
- a body having at least one cavity wall defining a cavity;
- a plurality of controlled electromagnets spaced about the at least one cavity wall;
- a housing having a curved outer surface defining an electromagnetically transparent opening, the housing curved surface rotatively positioned within the cavity;
- at least one magnetic positioner fixed to move with the curved outer surface;
- a rotor rotatively fixed within the housing, the rotor positioned to rotate by the housing opening;
- at least one rotor magnet fixed on the rotor;
- and
- at least one electromagnetic pickup disposed within the housing in proximity with the rotor, each pickup receiving a time-varying electromagnetic field from at least one rotor magnet as the rotor rotates.
