A turbo generator ( 1 ), including a stator and a rotor ( 2 ), has a rotating bell type exciter ( 3 ) connected to one end of the rotor ( 2 ) and the exciter ( 3 ) being equipped with at least one cooler ( 7 ). An axial duct ( 11 ) with a guide ( 12 ) is provided between a cylindrical housing ( 13 ) and the outer circumference of the bell type exciter ( 3 ). 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.
