Wind turbine/generator assembly. In general, a high speed of revolution is required for the generator in order to use rotational energy generated with the aid of a windmill to generate electricity. To avoid expensive and heavy transmissions which cost power it is proposed to construct the generator as a hypocycloid generator as a hypocycloid generator in which the rotor is coupled via a universal joint or other construction to the shaft of the wind turbine. With the interposition of rings, the rotor executes a rolling movement over the stator. Preferably the generator is constructed as a shortened flux generator, that is to say the flux that is generated in one pole flows back via an adjoining pole.
