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.
