Abstract
An internally cooled rotor for an acyclic generator has a ferromagnetic steel core to which is diffusion bonded a cylindrical copper conductor in which is embedded a multiplicity of cooling tubes communicating with coolant passages formed in the core. The cooling tubes are implanted in a hot isostatic pressure process during which the copper cylinder is at least in part created by the densification of copper powder to a non-porous mass.
