Disc type dynamo-electric machine, especially a generator, having two stators and one rotor, an active air gaps between each stator and the rotor, two annular energizing windings in the stators, and two non-active or auxiliary air gaps are formed in a smooth region between the stators and the rotor, the smooth region being closer to the hub than are the annular windings. The entire rotor is formed at least approximately as a disc of uniform strength. The stators are shaped to conform, in the region of the rotor. The magnet flux successively penetrates the two active air gaps and the two auxiliary air gaps and flows in a radial direction mainly by way of the yokes of the stators. Cooling ribs are provided.
