Combined magnetic suspension and rotary transformer

Claim 1

A VARIABLE RELUCTANCE ALTERNATING CURRENT ROTARY TRANSFORMER COMPRISING A STATOR OF MAGNETIC MATERIAL HAVING A PLURALITY OF SALIENT POLES ARRANGED IN AT LEAST TWO GROUPS OF THREE POLES, A COIL WOUND ON EACH OF SAID POLES, A FIRST CIRCUIT ENERGIZING THE COIL WOUND ON THE CENTRAL POLE OF EACH GROUP OF THREE, A SECOND CIRCUIT INTERCONNECTING THE COILS WOUND ON THE OUTER POLES OF EACH GROUP OF THREE SO THAT THE VOLTAGE INDUCED IN ONE OUTER COIL BUCKS THE VOLTAGE INDUCED IN THE OTHER OUTER COIL OF EACH GROUP, A ROTATABLE SHAFT, A HOLLOW CUP SHAPED ROTOR OF MATERIAL TERMINATING SAID SHAFT AND SUPPORTED WITHIN SAID STATOR BY SAID SHAFT, SAID ROTOR HAVING AN INNER MAGNETIC RING ISOLATED MAGNETICALLY FROM AN OUTER RING, SAID OUTER RING BEING SLOTTED TO PROVIDE TWO PROTRUDING POLES FOR EACH GROUP OF THREE STATOR POLES, SAID ROTOR HAVING A NEUTRAL POSITION WHEREIN ALTERNATE ROTOR POLES SPAN THE CENTER LINE DISTANCE BETWEEN ADJACENT STATOR OUTER POLES, SAID FIRST AND SECOND CIRCUITS THEREBY HAVE SUBSTANTIALLY CONSTANT SELFINDUCTANCE AND A MUTUAL INDUCTANCE PROPORTIONAL TO THE ROTARY DISPLACEMENT OF SAID ROTOR FROM SAID NEUTRAL POSITION, AND MAGNETIC MEANS MOUNTED WITHIN SAID HOLLOW ROTOR TO SUPPORT SAID SHAFT.
