MylowHJ Replication - Discussion

[starcruiser]

@Queue,

We provide just enough energy to rotate the disk a few degrees. As yours shows, it rotates over half way.

Why can't folks understand what this means?

BTW: Excellent work. I'm seeing the same. Please don't try closing the magnetic rotor loop. What I found is when that is done there is at least one place where the polarity flips 180 deg. even though the magnet's polarity is the same all the way around.

@BEP,

Have you tried to flip one set of magnets polarity when closing the loop to see what happens?

Well first of all his present rotors are shot, and, he can't just sit still and wait for his next rotors and not do anything. So for the "first time" (now I don't know if it's the first time but if I judge from his astonishment at explaining a simple stickie, one would then ask, geez is this the first time he's used straight magnets), I think he has tried straight magnets. lol

@Sterlinga if you can find out if in his last video, was this the first time he ever used straight magnets or is the object of the video to give a Discovering Stickies 101 Course and he's been using them for years. Both ways is OK with me because I now know why his wheel worked and that is OK with me.

@Wattsup

Here is Mylow playing with straight magnets:

@BEP,

My loop problems are with any ring of magnets. If I install a symmetric loop of magnets, all with the same polarity, then place a compass at the edge while spinning, the compass will always find one point where it disagrees with the physical polarity.

I just tried flipping that one magnet. No joy. The reversal appears to be between the magnets.

I understood this before. I don't know why I made that mistake.

So I don't close the loop. I'm back to having separate groups that aren't talking to one another.

"This would seem to be a case where small is beautiful. Size matters but in the inverse. The natural temptation to use more powerful magnets should be resisted. The discs should be as large as possible, the magnets as small and weak as possible consistent with the motor still working, obviously. One can then gradually increase each of the variables in turn until one generates a negative interaction and the motor stops working. In this way one will map out an operating envelope for the motor and determine which combination of variables gives most power, most speed, or whatever."

Allright, finally we're on the right track!  This is exactly why HJ used huge rotors on some of his rotary
designs - to spread the field out so it doesn't all turn into one giant sticky spot.  This localizes the
reactions allowing the vortical spin fields to work without being overpowered by those useless B fields.
After getting something to work, THEN we can slowly increase magnet strength while adding permeability plates to sink the B field.  This will then maximize the short range vortical spin fields.

On my own rep I'm using a 36" rotor and constructing the rotor magnets from 4" tall bar magnets
with 1.7 lb pull here http://www.mcmaster.com/#5851k11/=1eg8vc  with 1006 steel extensions to form the C shape.  This is the lowest pull strength I can find and it might be too much!  Then I have a one
inch wide roll of mumetal to use as the permeability shield to go around the outside of the magnets
at top and bottom. Then another steel circular shield mounted underneath the rotor magnets and yet another circular steel shield to sit on top of the magnets.  This should nuke the B fields!

Sounds rational. Good luck cc.
