Abstract
A turbo generator (), including a stator and a rotor (), has a rotating bell type exciter () connected to one end of the rotor () and the exciter () being equipped with at least one cooler (). An axial duct () with a guide () is provided between a cylindrical housing () and the outer circumference of the bell type exciter (). Thus, drawbacks of the prior art are mitigated and the efficiency of the bell type exciter is increased by recovering the dynamic energy of the cooling fluid flow.
