Abstract: In a preferred form, a cooling arrangement for a squirrel cage rotor assembly of an alternating current electric drive motor includes a pair of rotor end plates clamped to the ends of a rotor core carrying a pair of conductive end rings extending from the ends of the rotor core. The rotor end plates form end ring cooling cavities circumscribing the inner peripheries of the end rings. The rotor core is carried by the motor shaft and a recessed area on the outer diameter of the shaft forms axial cooling channels in heat conducting relation with the inner bore of the rotor core. A pair of concentric axial shaft passages extend through a bore in the center of the shaft and communicate with radial shaft passages connected with the end ring cooling cavities and with the axial cooling channels. A hollow insert is mounted in the shaft bore for separating the pair of axial shaft passages. A liquid coolant is circulated from one end of the shaft through the end ring cooling cavities and the annular cooling chamber to transfer heat from the end ring and the rotor core.

Abstract: A rotor for a dynamoelectric machine includes a laminated rotor core mounted on a shaft sleeve which is mechanically expanded by an interference fit with the motor shaft. A pair of rotor end supports are mounted on the shaft sleeve in an axially supporting relationship with the ends of the rotor core and in a circumferentially supporting relationship with the ends of a winding carried by the rotor core.

Abstract: In a preferred embodiment, a rotor for a dynamoelectric machine and method for manufacture includes a laminated rotor core mounted on a shaft sleeve which is mechanically expanded by an interference fit with the motor shaft. A pair of rotor end supports are mounted on the shaft sleeve in an axially supporting relationship with the ends of the rotor core and in a circumferentially supporting relationship with the ends of a winding carried by the rotor core.
