slightly smaller than said shaft diameter, said
protrusions being compressed onto said outer
circumferential surface portion of said shaft to
form a press fit between said lamination and said
shaft.
14. A method of assembling a rotor assembly for a
dynamoelectric machine comprising the steps of:
forming a shaft including an outer
circumference portion having a circular cross
section defining a shaft diameter;
forming a plurality of laminations, each
lamination having a central opening defining an
inner periphery, the inner periphery including a
plurality of radially inwardly extending
compressible protrusions defining a diameter
slightly smaller than said shaft diameter;
inserting said shaft into said central openings
of said laminations; and
compressing said protrusions against said outer
circumferential surface portion of said shaft to
form a press fit between said laminations and said
shaft.
The references relied upon by the examiner as
