Abstract
A rotor air cooling system including an outer housing and an inner housing configured to be inserted into the outer housing, the inner housing including an open backend. The system further includes a stator attached to an interior side of the inner housing, a main rotor body included in the inner housing, the main rotor body being arranged around a rotor shaft arranged to extend through the inner housing and the outer housing, wherein cooling air axially enters the main rotor body in an inlet end, passes through cavities of the main rotor body, and exits the main rotor body in an outlet end, and a water jacket arranged between the inner housing and the outer housing. Moreover, the system includes a heat exchanger for dissipating heat from the cooling air exiting the main rotor body.
