Title: By-pass channels for conducting cooling medium of generator being cooled by direct cooling on suction principle
Inventor: HEDIGER DANIEL
IPC: H02K5/20
Filed: 1999-04-19
Abstract: The generator has a main fan (11) on its rotor shaft which sucks the coolant heated by the heat generating elements of the generator out of the generator and transports it to a cooler arrangement.
