Abstract
A rotor assembly and method for a dynamoelectric machine includes a shaft having an outer circumferential surface defining a shaft diameter. The rotor assembly also includes a plurality of laminations, wherein each lamination has a central opening defining an inner periphery. The inner periphery includes a plurality of radially inwardly extending compressible protrusions defining an inner diameter slightly smaller than the shaft diameter. The protrusions are compressed as a lamination is mounted onto the shaft to form a press fit between the lamination and the shaft.
