Magneto rotor and method of manufacturing the same

Claim 1

A MAGNETO ROTOR, COMPRISING, IN COMBINATION, AN ANNULAR SUPPORT MEMBER HAVING A CYLINDRICAL INNER SURFACE OF A PREDETERMINED FIRST RADIUS AND HAVING A FIRST AXIS; A POLE MEMBER SHAPED SUBSTANTIALLY AS A SEGMENT OF A CYLINDER AND HAVING AN OUTER SURFACE OF A PREDETERMINED SECOND RADIUS AND HAVING A SECOND AXIS PARALLEL WITH SAID FIRST AXIS; AND A MAGNET MEMBER CONSISTING OF A MATERIAL SUBJECT TO SHRINKAGE AND BEING OF PREDETERMINED WIDTH AND LENGTH, CURVED IN LONGITUDINAL DIRECTION AND BOUNDED TRANSVERSELY BY AN OUTER CYLINDRICAL SURFACE PORTION HAVING A THIRD PREDETERMINED RADIUS NOT EXCEEDING SAID FIRST RADIUS AND HAVING A THIRD AXIS PARALLEL WITH SAID FIRST AND SECOND AXES, AND BY AN INNER CYLINDRICAL SURFACE PORTION HAVING A PREDETERMINED FOURTH RADIUS SMALLER THAN SAID THIRD RADIUS AND AT LEAST EQUAL TO SAID SECOND RADIUS AND HAVING A FOURTH AXIS, SAID THIRD AND FOURTH AXES BEING PARALLEL WITH EACH OTHER AND SPACED FROM EACH OTHER A DISTANCE OF SUCH MAGNITUDE THAT THE RADIAL THICKNESS OF SAID MAGNET MEMBER IS GREATER IN THE CENTER AREA THEREOF THAN ON BOTH SIDES THEREOF, SAID MAGNET MEMBER BEING FITTED BETWEEN SAID INNER SURFACE OF SAID SUPPORT MEMBER AND SAID OUTER SURFACE OF SAID POLE MEMBER, WHEREBY THE MAGNET MEMBER WILL BE ENGAGED BY SAID SURFACES OF SAID SUPPORT MEMBER AND OF SAID POLE MEMBER, RESPECTIVELY, ALWAYS AT LEAST IN SAID CENTER AREA, AND ANY SPACE LEFT BETWEEN THE CYLINDRICAL SURFACES OF THE MAGNET MEMBER AND THE RESPECTIVELY ADJACENT SURFACES OF THE SUPPORT AND POLE MEMBERS AS A RESULT OF SHRINKAGE OF SAID MAGNET MEMBER WILL BE RESTRICTED TO SURFACE PORTIONS SPACED FROM SAID CENTER AREA OF THE MAGNET MEMBER SO THAT RADIAL PRESSURES ON SAID MAGNET MEMBER WILL ALWAYS BEAR UPON THE CENTER AREA SUPPORTED BY SAID SUPPORT MEMBER AND SAID POLE MEMBER.
