AI Thread Summary
Rotating the stator in the opposite direction of the rotor in an electrical generator does not inherently increase electrical output. The discussion centers on a double eolic generator concept with two counter-rotating rotors, but efficiency remains a key concern. Increasing power output without additional input requires improved efficiency, which may be hindered by added complexity from extra components like brushes and bearings. The potential for increased complexity and cost could outweigh any benefits. Overall, the design may not be practical for enhancing energy production.

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.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
