Working Magnetic Motor on you tube??

[JAG]

Just looked at that one from zero, He needs to cover the rotor in cling film or something to stop the air flow. He'll get a large fan/drag effect from his design.

Sorry Rosphere too lazy to find the link, but somewhere in the development thread over at Steorn (I think about page 5 or 6) Al discusses the need for the Judson Dampers. Prior to using these, the device once "in sync" the stator would accelerate up to over 8000 rpm's, become unstable and drop out of sync. The dampers provide drag on the stator, to slow the acceleration and stator speed. They don't help accelerate the rotor and stator, they do the opposite and keep it "balanced" and in sync. This is what I find most interesting. Other ways can be found to provide that drag/control mechanism that can generate usable work.

Exactly, JAG - I read the same thing.  All suspicions are suspect at this point but I suspect that the reason that Al's motor quits above 8,000 rpm on the stators is that the stator bearings can't keep up with the rotor and the motor falls out of 'gear' phase. 

I remember reading in a Steorn thread that after Al got the machine going as always he started a second stator going AGW with RPM's in excess of 12,000.  Al hasn't posted in a while(black helicopters??). This was in one of his latter posts.

I read that too, but details were sparse. Lets get the replicators to get it working first before we make them double it

I have no doubt the replications will go just fine, and then adjustments will be tried and improvements made.

I also think it will have a fairly large latitude of operation( magnet size, rotor and stator size, spacing, etc.).

If the rotor is moving approximately 1000rpm and the stator @ 5000rpm. What coil configuration would work best, on the rotor or stator, to generate current.

I know - I'm jumping ahead here - But I'm an optimist.

Another replication from ZeroFosillFuel

But his stator magnet are way to big in my opinion

IMO, that vid is a joke. How can he say it's a replication when it clearly isn't even close???
WTF??? The mags aren't even close. I could go on and on but I think you get the picture.

I ordered some magnets from K&J today and will hopefully get my bearings and CNC
work done this week or next. This is gonna be fun.

You know....

I really don't understand how someone can call themselves a replicator of something when they don't even follow the build instructions! It's like someone trying to replicate a car engine without having a clue how it works..... Ok, I'm not going to start ranting.....
