Low inertia electric motors

Claim 1

A LOW INERTIA ELECTRIC MOTOR COMPRISING SPACED HOUSING MEMBERS, A STATOR BETWEEN SAID HOUSING MEMBERS, A CORE HAVING A CYLINDRICAL FIRST PORTION WITHIN SAID STATOR PROPORTIONED TO PROVIDE A RADIAL SPACE THEREBETWEEN, SAID CORE TERMINATING SHORT OF ONE OF SAID HOUSING MEMBERS AND HAVING A REDUCED SECOND PORTION ANCHORED TO THE OTHER OF SAID HOUSING MEMBERS, AN OUTPUT SHAFT CONCENTRIC WITH AND SMALLER IN DIAMETER THAN SAID CORE, SAID SHAFT EXTENDING THROUGH SAID ONE HOUSING MEMBER AND BEING ROTATABLY CARRIED THEREBY, AND AN ARMATURE HAVING A TUBULAR PORTION IN THE RADIAL SPACE BETWEEN SAID STATOR AND SAID CORE AND SUCH ARMATURE PORTION HAVING RADIAL OPERATING CLEARANCE OVER BOTH, SAID ARMATURE TUBULAR PORTION HAVING ELECTRICAL CONDUCTORS EXTENDING AND FORMING THEREOF AND STRUCTURALLY INTEGRAL THEREWITH AND FORMING A PART THEREOF, SAID CONDUCTORS BEING DISPOSED CLOSER TO THE INNER SURFACE OF SAID ARMATURE TUBULAR PORTION THAN TO THE OUTER SURFACE THEREOF TO PROVIDE FOR MAXIMUM STRENGTH OF SAID ARMATURE TUBULAR PORTION IN RESISTING CENTRIFUGAL FORCES WHICH TEND TO CAUSE RADIAL OUTWARD MOVEMENT OF SAID CONDUCTORS DURING ARMATURE ROTATION WHILE MINIMIZING WALL THICKNESS OF SAID ARMATURE TUBULAR PORTION, SAID ARMATURE HAVING RADIALLY INWARDLY EXTENDING END PORTIONS WHICH ENCLOSE SAID CORE FIRST PORTION WHILE BEING AXIALLY SPACED THEREFROM AND SAID ARMATURE END PORTIONS BEING INTEGRAL WITH SAID ARMATURE TUBULAR PORTION TO PROVIDE A UNITARY STRUCTURE OF MAXIMUM STRENGTH WITH MINIMUM WALL THICKNESS AND MINIMUM MASS, ONE OF SAID ARMATURE END PORTIONS BEING ANCHORED TO SAID SHAFT FOR UNITARY ROTATION THEREWITH AND SAID OTHER ARMATURE END PORTION HAVING RADIAL OPERATING CLEARANCE OVER SAID CORE SECOND PORTION.
