Inductor alternator having an annular stator construction

Claim 1

IN AN INDUCTOR ALTERNATOR, THE COMBINATION COMPRISING AN ANNULAR STATOR SURROUNDING A CENTRAL AXIS, SAID STATOR INCLUDING TWO GENERALLY SEMICIRCULAR PORTIONS OF MAGNETIC MATERIAL ARRANGED GENERALLY END TO END TO FORM AN ANNULUS AND TWO MAGNETIZING MEANS DISPOSED AT DIAMETRICALLY OPPPOSITE LOCATIONS ADJACENT THE ENDS OF SAID GENERALLY SEMICIRCULAR PORTIONS, A PLURALITY OF TEETH ON EACH OF SAID GENERALLY SEMICIRCULAR PORTIONS, EACH OF SAID TEETH HAVING A PRINCIPAL AXIS POSITIONED RADIALLY WITH RESPECT TO SAID CENTRAL AXIS AND HAVING ONLY A SINGLE FACE ON ITS FREE END ARRANGED PERPENDICULAR TO SAID PRINCIPAL AXIS, SAID END FACES OF SAID STATOR TEETH COLLECTIVELY DEFINING AN ANNULAR SERIES OF SUCH FACES SURROUNDING SAID CENTRAL AXIS, A PLURALITY OF ARMATURE COILS EACH OF WHICH IS RECEIVED BY AND SURROUNDS, A SINGLE ONE OF SAID TEETH, AND A ROTOR SUPPORTED FOR ROTATION ABOUT SAID CENTRAL AXIS AND INCLUDING AN ANNULAR SERIES OF TEETH DEFINING AN EVENLY SPACED ANNULAR SERIES OF END FACES WHICH MOVES IN CLOSELY SPACED RELATIONSHIP TO SAID ANNULAR SERIES OF STATOR END FACES AS SAID ROTOR IS ROTATED, THE NUMBER OF TEETH ON EACH OF SAID GENERALLY SEMICIRCULAR STATOR PORTIONS BEING A MULTIPLE OF THREE AND EACH SET OF THREE TEETH ON EACH GENERALLY SEMICICULAR PORTION BEING ARRANGED SO THAT THE VOLTAGE INDUCED IN THE ASSOCIATED ARMATURE COILS ARE 120 ELECTRICAL DEGREES OUT OF PHASE WITH ONE ANOTHER.
