Working Magnetic Motor on you tube??

[geodan]

Hi Jason,

very nice job on the drawings!

In my opinion Sean's version seems both more stable and flexible adjustment wise... which could be very important when it comes to fine tweaking...

I think that most of the difference is in the base plate... do you have any plans of doing a drawing based on Sean's model??

Thanks

Hi geodan,

I absolutely plan to build an adjustable model for further testing. I'm only sticking to the original model strictly for replication and validation reasons. The next version I make will be much more flexible to experiment with and optimize the design.

God Bless,
Jason O

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.

geodan, Jdo
I'm pretty sure Sean's model originated with CAD files of some sort as he uses his CNC machine to crank the pieces out. In that sense the drawings already exist.
Here's the base:

I agree. Another thought (helped by someone at Steorn forum) is that the Dampners are magnetic "sinks" which could result in a change of temperature. As we know even a slight change in temperature can be used to create usable work via a Sterling.

I'd be interested to see one of the replicators do a temperature test comparison of the Dampers pre and post run.
