The new generator no effect counter B. EMF part 2 ( Selfrunning )

[Cadman]

l0stf0x,

Please do not confuse your 3 phase stator with Syair's 1 phase stator, the winding layout is completely different.
Your stator winding is designed for the number of poles on the original armature. You should design your new rotor to duplicate the original as much as possible, particularly the number of stator slots per pole (arc of the pole shoe). There is a specific design for your 3 phase alternator that demands a certain number of slots per phase per pole and the span on the stator coils is set for the pole arc and number of poles of the original armature. Using any other number of poles, or arc of the pole shoes, will give a poor output or no output at all.

This applies to any 3 phase generator/alternator being modified, including automotive alternators where you do not intend to rewind the stator.

The steel for the new rotor should be laminated electrical steel, non-oriented. Ordinary mild steel will not flip polarities quickly and completely enough.

Also the rotor poles should be magnetically isolated from each other, not connected with iron on the ends.

The magnetic circuit should travel in a loop from one pole through the stator, back through the next pole and return to the starting pole. That means steel at the core, not non-magnetic material.

Cadman,
I agree with your assessment of the 3 phase stator but believe there are additional problems.
The principal behind it's supposed operation has never been determined.

Is it operating from flux switching or flux shielding. Simply rotating magnetized iron through the stator is no different than rotating magnets themselves and will perform the same. (drag with load)
In fact the alternator itself rotates only the iron rotor that has been magnetized and of course feels the drag with load.

If the concept of shielding was used then each stator pole should have it's own magnet for each winding and the shield could slide between them.
In this case the winding would only see one polarity and may be better to have two magnet for each winding shielding each at separate times to provide alternating fields.

If the concept of flux switching was used then each winding should have two magnets and have them switch at separate times to provide alternating fields also.

The big problem is the original design was never shown in any detail.

Exactly, but even his CAD drawing shows 4 pole shoes on each of the 2 stationary armatures. 162 magnets (2 he removed) with 5 rows per pole shoe (according to the drawing) with 4 magnets per row (according to Syair) = 160 magnets. I think the 40 poles he mentioned are these 40 rows of magnets.

But if Syair is to be believed then he did report success with his new version with the wound exciter coils too. 220V @ 55A.

And if he is to be believed then that style is the only one that could be used with a standard off the shelf stator (same number of poles as factory built) He did say that it took over 1 HP to turn the iron rotor (750 watts) and 320 watts for the exciter coils (80V @ 4A).

Yes, but that configuration would require 1500 RPM for 50hz output and what he shows and states in the video is that the generator requires only 100 RPM.
The cogging would also be only 4 major positions per rev and the video shows about 36 cogs per rev.

So the video does not match what is shown in the drawings.

Right. The first video is supposed to be Ramadan's design, not Syair's. Personally, I am not going to waste my time trying to figure out what's inside Ramadan's motor. There is nothing to go on.

It's Syair's newer design that has my attention.
