See full text

A rotor shaft for an electric motor includes an axially extending tubular body having an inner circumferential surface defining a hollow interior thereof with at least a portion of the hollow interior configured to receive a coolant therein. A plurality of circumferentially spaced splines extends radially inwardly from the inner circumferential surface into the portion of the hollow interior configured to receive the coolant therein. Each of the splines is configured to provide a heat exchanging structure for transferring heat from the rotor shaft to the coolant. The splines are one of integrally formed with the tubular body or provided as inserts captured by the tubular body during a flow forming process.
