Title: Rotating asynchronous converter and a generator device

Abstract: The present invention relates to a rotating asynchronous converter and a generator device. The converter comprises a first stator connected to a first AC network with a first frequency f.sub.1, and a second stator connected to a second AC network with a second frequency f.sub.2. The converter also comprises a rotor means which rotates in dependence of the first and second frequencies f.sub.1, f.sub.2. The stators each comprises at least one winding, wherein each winding comprises at least one current-carrying conductor, and each winding comprises an insulation system, which comprises on the one hand at least two semiconducting layers, wherein each layer constitutes substantially an equipotential surface, and on the other hand between them is arranged a solid insulation.
