Method of making stators

Claim 1

THE METHOD OF MAKING A STATOR HAVING STACKED INNER ANNULI WITH OUTWARDLY PROJECTING TEETH DEFINING WINDING SLOTS AND STACKED OUTER ANNULI EXTENDING AROUND THE TEETH ON THE INNER ANNULI COMPRISING, BLANKING OUT SETS OF INNER AND OUTER ANNULI FROM A SHEET OF MAGNETIC MATERIAL WITH THE ENDS OF THE TEETH ON EACH INNER ANNULUS EXTENDING CONTIGUOUS TO ANNULARLY SPACED PORTIONS ON A RESPECTIVE OUTER ANNULUS AND WITH RECESSES IN THE OUTER ANNULUS BETWEEN THE ANNULARLY SPACED PORTIONS THEREON, THE BLANKING OUT OF EACH INNER ANNULUS FROM THE OUTER ANNULUS PRODUCING A RADIAL OVERLAP BETWEEN THE ENDS OF THE TEETH ON THE INNER ANNULUS AND THE ANNULARLY SPACED PORTIONS ON THE OUTER ANNULUS, THE RECESSES HAVING AN ANGULAR WIDTH GREATER THAN THE ENDS OF THE TEETH AND SPACED RADIALLY OUTWARDLY FROM ADJACENT ANNMULARLY SPACED PORTIONS A SMALL DISTANCE SUBSTANTIALLY EQUAL TO THE RADIAL OVERLAP PRODUCED BY THE BLANKING OPERATION BETWEEN THE TEETH ON THE INNER ANNULUS AND THE ANNULARLY SPACED PORTIONS ON THE OUTER ANNULUS, STACKING THE INNER ANNULI WITH THE TEETH IN ALIGNMENT TO PROVIDE WINDING SLOTS THEREBETWEEN, PLACING ELECTRICAL WINDINGS IN THE SLOTS, STACKING THE OUTER ANNULI WITH THE RECESSES IN ALIGNMENT, AND ASSEMBLING THE INNER STACKED ANNULI INTO THE OUTER STACKED ANNULI WITH THE TEETH ON THE INNER ANNULI EXTENDING INTO THE RECESS IN THE OUTER ANNULI TO PROVIDE A SUBSTANTIALLY LINE-TO-LINE FIT THEREBETWEEN.

Claim 2

THE METHOD OF MAKING A STATOR HAVING STACKED INNER ANNULI WITH OUTWARDLY PROJECTING TEETH DEFINING WINDING SLOTS AND STACKED OUTER ANNULI EXTENDING AROUND THE TEETH ON THE INNER ANNULI COMPRISING, BLANKING OUT SETS OF INNER AND OUTER ANNULI FROM A SHEET OF MAGNETIC MATERIAL WITH THE ENDS OF THE TEETH ON EACH INNER ANNULUS EXTENDING CONTIGUOUS TO ANNULARLY SPACED PORTIONS ON A RESPECTIVE OUTER ANNULUS AND WITH RECESSES IN THE OUTER ANNULUS BETWEEN THE ANNULARLY SPACED PORTIONS THEREON, THE BLANKING OUT OF EACH INNER ANNULUS FROM THE OUTER ANNULUS PRODUCING A RADIAL OVERLAP BETWEEN THE ENDS OF THE TEETH ON THE INNER ANNULUS AND THE ANNULARLY SPACED PORTIONS ON THE OUTER ANNULUS, THE RECESSES HAVING AN ANGULAR WIDTH GREATER THAN THE ENDS OF THE TEETH AND SPACED RADIALLY OUTWARDLY FROM ADJACENT ANNMULARLY SPACED PORTIONS A SMALL DISTANCE SUBSTANTIALLY EQUAL TO THE RADIAL OVERLAP PRODUCED BY THE BLANKING OPERATION BETWEEN THE TEETH ON THE INNER ANNULUS AND THE ANNULARLY SPACED PORTIONS ON THE OUTER ANNULUS, STACKING THE INNER ANNULI WITH THE TEETH IN ALIGNMENT TO PROVIDE WINDING SLOTS THEREBETWEEN, PLACING ELECTRICAL WINDINGS IN THE SLOTS, STACKING THE OUTER ANNULI WITH THE RECESSES IN ALIGNMENT, AND ASSEMBLING THE INNER STACKED ANNULI INTO THE OUTER STACKED ANNULI WITH THE TEETH ON THE INNER ANNULI EXTENDING INTO THE RECESS IN THE OUTER ANNULI TO PROVIDE A SUBSTANTIALLY LINE-TO-LINE FIT THEREBETWEEN.
