A multi-piece rotor for a dynamoelectric machine includes a core which is bore mounted to a shaft, and one or more annular sleeves which are slip fit and glued onto the shaft, the annular sleeves being characterized by a plurality of longitudinally extending ridges formed along the inner surface thereof, with one or more grooves cut in the inner surface between adjacent ridges such that as the sleeve is assembled to the core, the ridges contact the core and, if tightly fit to the core, the grooves provide adequate space for the insertion of adhesive.
