An alternator for wind generator use employing a pair of stators having a rotor mounted therebetween in planar coaxial relationship. The stators have radially slotted coil forms integral therewith in which coils are wound in a serpentine fashion. The rotor is provided with an aluminum rim slotted in a radial manner inwardly of its periphery to hold permanent magnets, which magnets through the aid of the rim concentrate eddy currents in the coils in an improved manner.

A machine for generating electricity comprising: a pair of axially arranged spacedly positioned and fixedly mounted stators formed of non-conductive, non-magnetic material, a rotor formed of conductive, non-magnetic material mounted for rotation between said stators in parallel relationship thereto;

A machine for generating electricity comprising: a pair of axially arranged spacedly positioned and fixedly mounted stators formed of non-conductive, non-magnetic material, a rotor formed of conductive, non-magnetic material mounted for rotation between said stators in parallel relationship thereto; each of said stators comprising a plurality of coils mounted thereon to extend around its periphery in a serpentine manner on a surface thereof facing said rotor, said rotor being formed in the shape of a wheel provided with a rim of a predetermined width and defining a plurality of openings spacedly positioned around its periphery within said rim, the width of the portion of said rim extending radially outward of said openings in said rotor being greater than the width of the portion of said rim extending radially inward of said openings, a plurality of permanent magnet means one mounted within each of said openings, said magnet means being arranged in sequence around said rim such that polarization of adjacent magnet means cause a field reversal in said coils as said rotor is rotated between said stators in magnetic proximity thereto, said predetermined width being of a size sufficient such that eddy currents induced therein produce a magnetic field that aids rotation of said rotor.
