A dynamoelectric machine (e.g., an induction motor for an overhead ceiling fan or the like) is disclosed having a stator assembly and a rotor assembly with the stator assembly comprising a bearing support or end shield, a core mounted within the bearing support with the core having a bore therethrough for rotatably receiving the rotor body of the rotor assembly. The end shield has a central shaft stationarily mounted relative thereto and a pair of bearings, preferably ball or roller bearings, is provided for journalling the rotor body on the stationary shaft. More specifically, the rotor assembly includes a hub having a generally cylindrical body on which the rotor body is secured by means of an interference or shrink fit with the hub body having a longitudinal central opening therethrough receiving the stationary shaft and further having a mounting flange on its outer end.
