Hi Romero, good to read you again. I wonder if the input current is important too? Many here are trying to keep the input current at minimum, while I noticed in your self-running video you showed us 1 Amp! Aren't we heading in the wrong direction?

Hi,
I would like not to reffer to that muller device I had. What I am talking is about speed under load or short. I read on the forums people saying that we cannot have any benefit from this effect and we will never have higher speed than without the generator coil in place. I don't wanna start another conflict with some of the clever brains and because of that I am not insisting to prove they are wrong.
It will be easy for the people who managed to have acceleration under load/short to measure the rpm before adding the generator coil and again after the generator coil is in place.The only important thing is  to  use the right sequence, as I said before, the effect will take place at more than one place and the right core material is of a great importance.
Lately i discovered that the shape of the magnets and the shape of the core are very important too. Cube is better than round for the magnets. If the core has the end facing the rotor in a conical shape it is better too.
Just having the edge of the core polished a bit will make a difference, more sharp that cone will be even better.
Unfortunately I discovered some of this recently and I built my new generator with round magnets but the cores I managed to improve. It will not make a huge difference but sometimes little things counts.

Regards,
Romero

Thank you for sharing that.
Would you be so kind to share if you have found any relation between magnet size and core size.

I'm in the process of ordering the parts and I would really like to know which works best?

Thank you and best regards.

There are advantages in both cases, having the core smaller than the magnet and having the magnet the same size with the core. In the current setup I have, the core is 19mm dia and the magnet is 30mm dia. I do have rotors with 20mm dia magnets too  but i have not tried them yet. I also have 2 rotors where I have magnets 30mm and a 20mm on top, making it look like a mushroom or cone.
I am waiting next week to get few more components then I will start testing.
Answering your question is difficult as I am in testing stage too.

Romero

dear romero,
Just 1 simple question, and i need 1 simple answer.
I think people should work things out in small scale 1st.
will it work in any size?  iam thinking about micro sizes,  micro magnets and mini rotor and mini coils...

I have tested 3mm dia magnets with small coils and worked too. I am not suggesting anyone to follow my way and spend lots of money, I have been wrong many times and I had to buy new stuff and start again. Small is always good and cheap.
