Beschreibung
Zusammenfassung:	A turbine power generator 20 includes a housing 22, a shaft 24, a turbine 26 to drive the shaft, a shaft-driven generator rotor 28, and generator stator 30 within the housing and surrounding the rotor. A main cooling gas blower 32 includes at least one blade 34 driven by the shaft 24 for causing a main flow of cooling gas to cool the rotor 28 and/or stator 30. A supplemental cooling gas blower 36 is connected in parallel with the main cooling gas blower 32 for causing a supplemental flow of cooling gas through the housing 22 in addition to the main flow of cooling gas to cool the rotor 28 and/or stator 30. The supplemental cooling gas blower may include an electric motor 38 and at least one blade 40 driven thereby. A controller 39 may be connected to the electric motor 38 to permit selective operation of the supplemental cooling gas blower 36.
