Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

[gotoluc]

Hi Didier, what if we consider magnetization time and and make the rotor and stator segment very long.

In most electric motors the rotor and stator segments are at most 30 degrees or less in length. So if you build it that way I don't see an advantage. But what if the segments were 90 degrees long, since once the magnetization has occurred there is no extra cost to attract a very long rotor segment, no?

If you wish I can give you some measurements on how much weigh the magnetization can lift including a standard motor air gap.

Let me know

Hi Luc, as said elsewhere, I am not skill enough in this area to answer you with any certainty.

But what about just two rotating barres (for the balance) with 4 reluctant switched coils magnets as stator at 90°, that you can change with ordinary electromagnets, wouldn't be easier to test?

In my humble opinion, it would be the minimum do to in any case.

Thanks for your Interest, Luc, for your experiments,

Yes Didier, your test suggestion is good and I may do something like that if it is needed.
However, as you may know Robert Murray-Smith is presently looking into the matter and I'll wait till he posts his new video demo with his calculations.

Thanks for your interest

Hi Luc, I did a test where I put 4  I  strips on my big neo (2 on each side) to match the length of a secondary coil from a MOT (on it's edge),and placed ceramic's between the I's in the hole of the secondary. Then I put another  I  across the ends of the 2 on each side. It still has 2 poles ,but when the coil is pulsed , it makes the poles change.
The way you have it , it's either magnetic or it's not?
A very weak field but it is there.

Can you draw a simple image of what you have done? I can't tell from the written description. Thanks in advance for any help. I'm looking for the switching of poles as you describe. The best I can come up with so far is basically two of gotoluc's devices but that would be twice as heavy with only half of the magnets being used at any given time. Would also take more power to switch two Alnico's.
