gasgekuehlter rotor of an electrodynamic machine

摘要

P the invention relates to a rotor of the electrical machine is cooled by circulation of gas. / p & & p & the cooling channels powered with cold gas from a channel under - notch 12 form at each axial spacing, at least in the levels superiors b of the notch, a network parallel comprising an upstream channel 34, a plurality of transverse channels 36 composed of the splines 40 in the conductive strips, and a downstream radial channel 38, of a manner to increase the area of exchange of heat at these levels superiors and to avoid their excessive heating despite the heating of the gas in the levels lower a. / p & & p & application to the rotors of alternators. / p
