Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
AN ELECTROMAGNETIC MOTOR COMPRISING A PAIR OF SPACED FIELD MEMBERS, A PAIR OF MOVABLY MOUNTED ARMATURES, SAID FIELD MEMBER HAVING OPPOSED POLE FACES, COIL MEANS FOR PRODUCING MAGNETIC FLUX IN ONE OF SAID FIELD MEMBERS, EACH OF SAID ARMATURES BEING MOVABLE BETWEEN A PAIR OF OPPOSED FIELD POLE FACESPROVIDING A SERIES MAGNETIC CIRCUIT IN WHICH SAID MAGNETIC FLUX PASSES FROM SAID ONE FIELD MEMBER THROUGH ONE OF SAID ARMATURES THROUGH THE OTHER FIELD MEMBER AND THEN THROUGH THE OTHER ARMATURE.
Claim 2
Dependent Claim
80 words
AN ELECTROMAGNETIC MOTOR COMPRISING A PAIR OF SPACED FIELD MEMBERS, A PAIR OF MOVABLY MOUNTED ARMATURES, SAID FIELD MEMBER HAVING OPPOSED POLE FACES, COIL MEANS FOR PRODUCING MAGNETIC FLUX IN ONE OF SAID FIELD MEMBERS, EACH OF SAID ARMATURES BEING MOVABLE BETWEEN A PAIR OF OPPOSED FIELD POLE FACESPROVIDING A SERIES MAGNETIC CIRCUIT IN WHICH SAID MAGNETIC FLUX PASSES FROM SAID ONE FIELD MEMBER THROUGH ONE OF SAID ARMATURES THROUGH THE OTHER FIELD MEMBER AND THEN THROUGH THE OTHER ARMATURE.
Claim 3
Dependent Claim
126 words
AN ELECTROMAGNETIC MOTOR COMPRISING A PAIR OF SPACED FIELD MEMBERS AND A PAIR OF ARMATURES SUPPORTED BETWEEN A PAIR OF NONMAGNETIC FRAME MEMBERS, ONE OF SAID FIELD MEMBERS HAVING POLES AT BOTH ENDS THEREOF AND A COIL FOR PRODUCING MAGNETIC FLUX THEREIN, MEANS SUPPORTING SAID ARMATURES FOR OSCILLATION ABOUT PARALLEL SPACED AXES, THE OTHER OF SAID FIELD MEMBERS EXTENDING BETWEEN SAID ARMATURES ADJACENT THEIR AXES TO PROVIDE A LOW RELUCTANCE PATH BETWEEN SAID ARMATURES, AND RESILIENT MEANS BIASING SAID ARMATURES TO REST POSITION ADJACENT SAID FIELD POLES, ENERGIZATION OF SAID COIL CAUSING SAID ARMATURES TO ROTATE IN OPPOSITE DIRECTIONS FROM SAID REST POSITIONS, SAID FIELD MEMBERS AND SAID ARMATURES FORMING A SERIES MAGNETIC CIRCUIT WHEREIN SUBSTANTIALLY ALL OF SAID FLUX PASSES THROUGH EACH OF SAID ARMATURES.
Claim 4
Dependent Claim
