SUMMARY

The discussion centers on the efficiency of a double eolic generator design featuring two rotors spinning in opposite directions. It concludes that rotating the stator in the opposite direction of the rotor does not inherently increase electrical output. Instead, the focus should be on enhancing efficiency through design improvements. Adding complexity, such as a second set of brushes and larger gaps, may detract from overall performance and increase costs.

I was wondering me if an electrical generator produces a larger amount of electrical energy if I rotate the stator on the contrary direction that of the rotor one.

Well, I was thinking in a double eolic generator, with two rotors spinning opposite. One rotor attached to the electrical rotor, and the other one attached to the electrical stator.

What do you think, cowboys?

Well the only way to increase power output for the same power input would be to increase efficiency. Adding a second set of brushes and larger gaps (because of the two counter-rotating concentric assemblies and their tolerances) would be seem to be counter productive to that goal. Plus the additional brushes, contacts and bearings add to complexity and cost.
