Axial air gap motor

Claim 1

A DOUBLE AXIAL AIR GAP POLYPHASE INDUCTION MOTOR COMPRISING, A PAIR OF STATORS SEPARATED BY AN AXIAL RADIALLY-ANNULAR FLUX GAP, EACH STATOR COMPRISING A MAGNETIC CORE HAVING TOWARD SAID GAP AN ANNULAR MAGNETIC FACE CHARACTERIZED BY A LARGE PLURALITY OF SALIENT POLE TEETH AND BY RADIAL SLOTS WHICH INTERVENE SAID TEETH AND ARE EQUIANGULARLY SPACED ENTIRELY AROUND THE FACE, A PAIR OF FRACTIONAL-PITCH LAP-WOUND POLYPHASE WINDINGS OF WHICH EACH IS ON A RESPECTIVE ONE OF SAID CORE FACES AND IS COMPRISED OF A PLURALITY OF PHASE BELTS OF ADJACENT COILS OF WHICH ALL COILS IN EACH BELT ARE FOR CURRENTS OF ONE PHASE, EACH COIL OF EACH WINDING BEING RECEIVED IN NON-ADJACENT ONES OF THE SLOTS OF THE CORRESPONDING FACE SO AS TO FORM A LOOP AROUND A PLURALITY OF POLE TEETH OF THAT FACE, SAID TWO WINDINGS BEING RESPONSIVE TO CURRENT ENERGIZATION TO PRODUCE RESPECTIVE MAGNETIC FIELDS ROTATING IN MAGNETIC PUSH-PULL RELATION IN A COMMON DIRECTION AROUND SAID GAP, AND A ROTOR HAVING AN ANNULAR ELECTROCONDUCTIVE PORTION WHICH IS AT LEAST PREDOMINANTLY NON-MAGNETIC AND WHICH IS DISPOSED IN SAID GAP, SAID ANNULAR ROTOR PORTION AXIALLY EXTENDING FROM SIDE TO SIDE OF SAID ROTOR, AND SAID ANNULAR ROTOR PORTION BEING RESPONSIVE TO SAID FIELDS TO BE ROTATED THEREBY AND TO BE AXIALLY REPELLED FROM EACH OF SAID STATORS.
