ABSTRACT:
A rotor for hydrogen-cooled rotary electric machines is provided with a gas inlet chamber and a gas outlet chamber which are circumferentially defined by radially extending partition walls and disposed in a region between a retaining ring holding rotor windings in position and a rotor shaft. Rotor cooling gas is introduced through a gas inlet port to a gas inlet chamber to flow to a gas outlet chamber divided into a plurality of zones while cooling the rotor windings. Form the gas outlet chamber, the gas flows through axially extending passages to a plurality of fan-like ventilating means to be discharged outside of the rotor.
