Working Magnetic Motor on you tube??

"[C]ould one of you Steorn users pass along the blueprint PDF file to Al? I am almost certain everything is correct in it but I would feel even better to know that he approves of the dimensions I put in it."

Jason, your blueprint was pointed out to alsetalokin two days ago.  He said you did a great job, and suggested a slight modification:

Wow! That looks like something I could build!
That's a really good job, Jason.
I see you even put the thread fit class in.
The only thing I would add or change is the rotor axle. I know it's what I showed in most of the pictures. But if you look at the later ones, you will see a 3.5 mm shaft instead of the 1/4-20 brass screw, and the 1/2 in hole in the rotor has been "plugged" with a Delrin insert to adapt to this shaft. The shaft is mounted in a dual ball bearing holder with a spring compression end-play eliminator, and the holder in turn is mounted on the base, in lieu of the brass screw. The rotor now simply slides on and off the shaft. For upside down runs I secure the rotor with a little retaining collar with a setscrew.

It's nice to see a real engineering drawing for a change. I usually just sketch stuff on napkins, and that makes it hard to see those leftover bits of food that are so tasty in the middle of the night.

(And he's right, it is a great job.)

Thanks!

I completely missed that post  .

I would be happy to add the axle assembly to the blueprints but I'm not sure what the dual ball-bearing holder with the spring compression end-play holder (wow what a mouth full) looks like. Is that something you can buy already like that or did he custom make it? Is there any way I could get more information on it. Maybe even a rough dimensioned sketch of the assembly? If so, I'd be happy to add it to the blueprints.

One other thing I'm wondering is if the motor still works alright with the screw as the shaft as opposed to the 3.5 mm one?

God Bless,

I got news from Butch (and so from Dusty):

"Nicolas,
Dusty received 3/16" magnets and needed 1/4". New magnets should be in by Monday. Also, the original builder said the rotor has to be the material he used and not clear plastic so the mass will be the same as well as static electricity properties. Dusty is making a new rotor so it will match the original design exactly. Then if it is successful, try it with the clear plastic rotor.
Butch"

So sorry to say guys, but we are still waiting for magnets..

G'day all,

I believe my first post on this thread. I have been following for a few weeks (read all of postings)

Toolmaker by trade (retired by circumstances not age  or ability), though a lot of experience with electro/mechanical devices.

This has been mentioned before no doubt, though I shall again, to replicate a device all dimensions and materials used in original device should be strictly adhered to, otherwise not a replication.

Everything, is in the information and if i may say Duplicate, then experiment.

For the duplicators/replicators.

ps. I at present would kill for some basic equipment!!!!!!!    Keep up the excellent work

Jason, I posted your questions about the rotor axle design in a location where alsetalokin will see them:

I should mention also that Doug Furr, the Ph.D. Mechanical Engineer who built our 1/4-scale Perendev Magnet motor (with Brady's permission, but which we couldn't get to work) http://video.google.com/videoplay?docid=6189540769300973039, expects to finish today his replica of your magnet motor design built by Al.  [...]  All his parts: magnets and bearings, will be arriving today.

Doug got his parts, but didn't have time to machine the thing.  He might be able to get back to it over the week-end, but he has a patent on another project that he has to finish by Monday.

A couple of funny things.

Doug said that when he was calling the magnet guys they commented something to the effect that all the sudden people were ordering this one kind of magnet, and they ran out.  They didn't know why there was this sudden rush.  I guess no one told them.

Doug didn't have this problem because he's going 1.5-scale.  However, when the magnets arrived, the bill was like $600.  It turns out that rather than ordering 1 pack of 10, and one pack of 5, they ordered 10 packs of 10 and 5 packs of 5; so they're loaded with magnets.
