Flux-switched inductor alternator

Claim 1

An inductor alternator comprising: a rotor mounted for rOtation about its axis, said rotor having two axially spaced radially extending toothed portions formed about the periphery thereof, each toothed portion including at least one tooth, each tooth of one of said portions having an associated tooth of the other portion oppositely disposed on the rotor periphery; means for generating a magnetic flux in said rotor; at least two elongated stator bars mounted concentrically of and parallel to said rotor axis, each of said stator bars being oppositely disposed of another of said stator bars to define an associated pair of stator bars, said stator bars being radially spaced from said rotor, each of said stator bars further having inwardly extending radial projections at the ends thereof, the ends of each of said projections confronting respectively one of said toothed portions on said rotor across a radial air gap; at least one ferromagnetic flux annular ring disposed coaxially of said rotor, said ring being magnetically coupled to and supported by an associated pair of oppositely disposed stator bars; and a plurality of solenoidal output coils wound radially about the cross-section of each annular ring; whereby upon energization of said magnetic flux generating means, rotation of said rotor through at least one revolution causes the magnetic flux in each annular ring to alternately switch direction to thereby induce an alternating voltage in said output coils.
