Miniature electric synchronous motor

Claim 1

A MINIATURE SYNCHRONOUS ELECTRIC MOTOR COMPRISING, IN COMBINATION, A CASING; A BEARING CARRIED BY SAID CASING; A SHAFT ROTATABLE IN SAID BEARING AND HAVING AN INNER END WITHIN SAID CASING, AND AN OUTER END; A STATIOANRY CIRCULAR CROSS SECTION ANNULAR PERMANENT MAGNET FIXED NON-ROTATABLE WITHIN SAID CASING AND CONCENTRIC WITH SAID SHAFT, SAID PERMANENT MAGNET BEING MAGNETIZED RADIALLY TO PROVIDE NORTH AND SOUTH POLES ALTERNATING THEREAROUND AT EQUAL ANGULAR SPACINGS; AN ANNULAR EXCITING WINDING CONCENTRIC WITH SAID SHAFT AND ARRANGED FOR CONNECTION TO A SOURCE OF A.C. POTENTIAL; ANNULAR MAGNETIC YOKE MEANS CONCENTRIC WITH SAID SHAFT AND EMBRACING SAID WINDING; A NON-MAGNETIC SPACER SECURED TO THE INNER END OF SAID SHAFT TO ROTATE WITH THE LATTER; A MAGNETIC MATERIAL ROTOR SECURED TO SAID NON-MAGNETIC SPACER, SAID ROTOR INCLUDING A CIRCULAR BODY PORTION LYING IN A RADIAL PLANE THROUGH SAID SHAFT AND A PLURALITY OF POLE TEETH PROJECTING FROM THE PERIPHERY OF SAID BODY PORTION AT UNIFORM ANGULAR SPACINGS THEREAROUND; THE NUMBER OF SAID POLES BEING AN EVEN MULTIPLE OF THE NUMBER OF SAID POLE TEETH; SAID WINDING, WHEN ERNERGIZED, PRODUCING AN ALTERNATING MAGNETIF FIELD IN AN ALTERNATING MAGNETIC FLUX PATH INCLUDING SAID WINDING, SAID YOKE MEANS, SAID ROTOR AND AN AIR GAP BETWEEN THE FREE ENDS OF SAID POLE TEETH AND SAID YOKE MEANS; SAID POLE TEETH EXTENDING IN OVERLAPPING SPACED RELATION TO SAID PERMANENT MAGNET POLES TO PROVIDE DIRECT MAGNETIC FLUX PATHS EACH INCLUDING A RESPECTIVE NORTH POLE, A RESPECTIVE POLE TOOTH, AND A RESPECTIVE SOUTH POLE ANGULARLY ADJACENT THE RESPECTIVE NORTH POLE; SAID ALTERNATING AND DIRECT MAGNETIC FLUX PATHS INTERLINKING IN SAID AIR GAP; EACH POLE TOOTH, UPON DE-ENERGIZATION OF SAID WINDING, LYING ANGULARLY INTERMEDIATE A RESPECTIVE NORTH POLE AND A RESPECTIVE SOUTH POLE; ALL OF SAID POLE TEETH, UPON ENERGIZATION OF SAID WINDING, BEING MAGNETIZED WITH THE SAME INSTANTANEOUS POLARITY WHEREBY, UPON SUCH ENERGIZATION OF SAID WINDING, ALL OF SAID POLES ARE ATTRACTED IN THE SAME ANGULAR DIRECTION TOWARD THE ASSOCIATED RESPECTIVE PERMANENT MAGNET POLE HAVING THE OPPOSITE POLARITY AND REPULSED IN SUCH SAME ANGULAR DIRECTION, BY THE ASSOCIATED RESPECTIVE POLE HAVING THE SAME POLARITY.
