Step motor using printed circuit components

Claim 1

AN ELECTRICAL MULTIPOLAR AXIAL AIRGAP ROTATING MACHINE OPERABLE IN A STEP BY STEP FASHION FROM A CHANGEOVER OF THE CURRENT SUPPLY CONNECTIONS TO THE TERMINALS OF THE ROTOR WINDING OF THE MACHINE, COMPRISING THE COMBINATION OF A STATOR HAVING AN INDUCTOR STRUCTURE ESTABLISHING MAGNETIC POLES SPACED ABOUT THE AXIS OF THE MACHINE, A ROTOR HAVING A WINDING MADE OF FLAT CONDUCTORS INTIMATELY SECURED TO THE INSULATING FACES OF AN ANNULAR CARRIER OVER WHICH THEY ARE DISTRIBUTED IN TWO SETS OF HALFTURNS WITH FACE-TO-FACE CONNECTIONS BETWEEN THE ENDS OF THESE HALF-TURNS TO FORM A CLOSE-CIRCUIT WINDING, AT LEAST TWO PAIRS OF BRUSHES SPACED ABOUT THE AXIS OF THE MACHINE, ADJACENT PAIRS OF BRUSHES BEING ANGULARLY DISPLACED BY ONE POLAR PITCH, EACH PAIR OF BRUSHES BEING LOCATED IN A PLANE MIDWAY BETWEEN TWO ADJACENT MAGNETIC POLES, TWO RINGS OF CONDUCTOR SEGMENTS MOUNTED CONCENTRIC WITH THE MACHINE AXIS, EACH SEGMENT EXTENDING SUBSTANTIALLY OVER ONE HALF OF THE POLAR PITCH AND THE SEGMENTS IN ONE RING BEING DISPLACED RELATIVE TO THE SEGMENTS OF THE OTHER RING BY ONE-HALF POLE PITCH, SAID BRUSHES OF EACH PAIR BEARING ON SAID TWO RINGS RESPECTIVELY, A CONNECTION EXTENDING FROM EACH SEGMENT OF SAID RINGS TO AN INDIVIDUAL POINT ON SAID WINDING, THE CONNECTION POINTS TO TWO ADJACENT SEGMENTS IN EACH RING BEING SPACED APART BY ONE-HALF OF THE POLAR PITCH, AND THE CONNECTION POINTS FOR THE SEGMENTS IN ONE RING BEING LOCATED MIDWAY BETWEEN THE CONNECTION POINTS FOR THE SEGMENTS IN THE OTHER RING, A PAIR OF CURRENT SUPPLY TERMINALS, AND A TWO-POSITION TRANSFER SWITCH FOR ALTERNATELY CONNECTING SAID CURRENT SUPPLY TERMINALS THROUGH SAID SEGMENTS AND BRUSHES TO SELECTED PAIRS OF CONNECTION POINTS ON SAID WINDING TO PRODUCE PROGRESSIVE STEP-BYSTEP MOVEMENT OF SAID ROTOR.
