I think like what you said, made a lot of sense about the stators being free to move but need timed constraints. The gear setup would apply resistance(physical), 13 fold times how many gear surface contact points, thats a lot. I would say that would be a last resort till all others have failed. Its a lesson that can be learned fairly quick with only 1 geared stator. But if you feel strongly toward the gears, instead of the tinies tryouts, lemme know. I think the tinies have strong possibilities.


Thoughts on tinies:

The opposite tinies have opposite polarity, right? It just might work. Go for it and let's see what happens.

Hi OC

Messed with the tinies and I like some things going on but I think the disk is acting as a damper to speed changes and Im making modifications for this. Once the flywheel action is reduced, the effects should be more prominent and presentable. Me hopes.

Im trying to reduce the mass of the tiny assy down to a point that the majority of it is the tinies. Ordering magnets this week in tinier fashions so I can mess with combos of more than 2 also. But while I wait for those, these should show some things meanwhile.

Also have thoughts of a secondary rotor below the main to influence the tinies with tinies. This is even more interesting if you think about the new posibilities.
All of these ideas are derived on thinking about how to accomplish what you need while trying not to affect the rotor/ stator fields much, and staying away from physical rotor/stator contact.

Will keep you updated. Wish I had more time in my days, in fact in my life all together.

Now that's an IDEA! Why didn't I think of that? Much better than gears.

Wink the seed grows, and spring is here.

I say we whipit, whipit real good.

Tiiiiny bubbles, in the wine.....

It is a new approach and worth the time. And its kinda easy.

Oh forgot to mention that my thoughts on using the Al slugs to affect the tinies would probably be speed dependent. So I think using them in conjunction with the rotor movement would be better. Think?

My thoughts were leaning towards magnet tinies interacting with magnet tinies. I don't think aluminum slugs would provide strong enough repulsion. If the spacing between rotor and subrotor is great enough, the tinies should not interfere with the primary rotor/stator interaction.

It may be mistakenly taken as if I was claiming to put the slugs on the rotor, but I meant by the word Them I was refering to the stator tinies working off of rotor movement instead of the stationary slugs. Ive been tired and not good at catching my goofs.

And a post above that verifies that is what I meant here.

Tinies and tinies is the method to go with.

My earlier suggestion of using the slugs on a disk below the stator were derived at adding just a bit of drag to accomplish the goal. But the wee ones on wee ones of a sub rotor( nice call, I dont have the right words for things all the time) can give a whole lot of control parameters. And should be effective.
Sorry for the confusion.

Got a vid coming but I gota wait to get home to upload, the mib infiltrated my shop, and I offered them a cake. They took the milk, everything!

na, but it wont upload from here, be maybe an hour.

I put the tinies in a closer radius to the stator and it shows promise. Still workin it on the rotor mags.

I didnt get a chance to order the tinies yet. Tonight. Lots. Cheap! Shweet! Nanomags!!

Plain means Playin' ? So it's not M & M's? Mr. Green

(Magluvins & Motors) LOL.

Nice slide action on that stator, but we need some way to flip it back (or forward) so that the next passing rotor mag will get a push from it. If you line up the magnets in various positions, you will find that parallel poles aligned equitorially will offer the most force. Now, how do we get it stay there or get there without adding any negative torque to the rotor?

Cheers

Cool

Timing needs a bit of work. Dunno if it's possible when tinies are interacting directly with rotor magnets which are interacting with stators. I think we might need to set up a subrotor with more tinies and let them interact independently from the stator & rotor magnets.

And I still think it needs to be scaled up with more stators than rotor magnets.

Good work. Very interesting stuff.

Nice idea and vid. Hmm one could use such to allow better control of them stators, like the slip positions, vibration and so on.

Fun stuff.

Thanks
Missed ya LC good to hear from ya. Wink

I agree with the sub rotor. I have to get more wee ones. Also im trying to look at how it reacts in my head with lil experiments. I dont want to just end up with a Bowman rig.

But Im drawn to it like a magnet! Mr. Green

Harvey, thanks

This is why the tinies came to mind. Hopefully we can use them in a way that when they do come into play, that their interactions are only slightly affecting the stator position, and not rotor spin. The heavier rotor you all have is helpful also.

If the arrangement with the Sub Rotor Oc suggested, is timed with the wee ones right, then we have a way of affecting the stator movement very accurately, and hoping for the least drag on the rotor movement.
Like a control for pole switching.

Just playing with my magnet collection. Who was it said something like "insanity is doing the same thing over and over again, expecting different results." Think it was somebody on this forum talking about Albert Einstein, but I could be wrong. I often am.

Mine aren't getting rusty, but they aren't getting as much exercise as they should. Doin something else at the moment, but when that is done or if I get a break from it, those bearings will be begging for a vacation. Wink

Yeah I think that was me, That saying has run my life LOL

I Got 65 mustang I'm trying to weld a new frame on, could use some really BIG Magnets to hold it in place. Gotta take advantage of the warm weather.
Keep the faith

Yeah, Droid, maybe it was you!
Speaking of big magnets, I have a couple of 4" x 6" x 7/8" (approximate size) magnets found in salvaged military junk. They aren't neo, not terribly strong (don't think they'd hold that frame together), but the magnetic field reaches way out. Playing with fields within these fields.

To OC—I'm going to rattle those ball bearings as soon as I can find a couple of pulleys or gears with precisely 4:1 ratio (with the smaller gear/pulley approximately 1" so that it'll be big enough to work with). I'm working on a mechanical way for the rotor to guide a stator in a rocking motion. Something tells me friction is going to be high, and I might be fooled into thinking these new-fangled magnets are stronger than they are.

Cheers

Mine has too much sentimental value to part with Sad

Besides, it has become quite useful in my pendulum experiement.

Sorry to hear of the MDF integrity issue. Odd that the smaller one worked ok, but the larger one didn't. I wonder if instead of machining slots if some type of holder could just be fastened to them. Just thinking out loud.

As LC posted in your thread, we don't see how the stators can provide the force required to accelerate the rotor in the time shown. The current consensus is that Al powered the rotor by some means.

Cool

(I already got the magic magnets. I just forgot the incantation. Tell Santa to bring me a few more brain cells.)
