ROTOR WITH A GROOVE BASE CHANNEL FOR A TURBOGENERATOR

摘要

The invention relates to a rotor for a rotating electrical machine, in particular a turbine generator. Said rotor comprises a rotor body with several axially extending winding grooves which are arranged parallel to each other and which are distributed on the periphery, said grooves comprising respectively at least one groove base channel which is arranged radially inwards for guiding a cooling gas. At least one groove base channel is at least partially thermally insulated with respect to the rotor body.
