Feb2006, the three rotor magnets will keep the opposing three stator magnets down in your construction. How about the rest of the descended stator magnets, how are they gonna be kept steadily down without a motor cap or springs?

I think Feb2006 has a point here, the rest of the descended stator magnets will just stay down because of gravity. Remember there is no opposing magnet  that might make them move up! So if we can agree on the slightly tilted stator magnets to keep them down then I'm ready to give up on the springs.

Feb2006, How far you think we have to tilt the stator magnets? Few degrees should do i think....

That seems the opposite of the construction we're discussing. What is the advantage, though?
Yep, that's exactly the opposite, i don't think it's a good idea to go for that at this stage. Too far off from Torbay's prototypes....

I think zero degree ,the forces up are very smal it wont stop it.
I only tilted the arm down so you should stop puting the spring in.

I only want a easy replica to build,so we can verify Torbay.

I go for the all around cap and wheel to hold down ,lift and descend.

The spring maybe is good for improvement later.

Feb2006, if it's for simplicity, wouldn't it be simpler to use Torbay's design with stationary magnets, each one supplied with a small wheel to be pressed by the motor cap? Each of these stator magnets (or the piece they're embedded in) would easily be beveled to allow raising the magnet by an easily attachable large wheel. Seems to me that would be easier to manufacture.

@georgemay:
Don't quite get what you mean by that. Do you mean leave all the staor magnets up and get them down by a guiding system as the rotor approaches? Could you make a little drawing of that idea?
[/quote]

Oh absolutely not at all.  All Magnets stay low except one.  Like in the patent drawing rotor will approach the gap in the stator ring.  While rotor is close to the raised arm it will add repeling force to raised arm.  So my idea was to lower it down before rotor was even close  to it. Like one or two magnets away.  This way lowering arm has to overcome only repeling force among the stator magnets.
Maybe I am a little ahead and there is to early to talk about timing issue.

On the practical side. Is there anyone who has access to a manufacturing facility (with a llathe and milling machines and so on) to whom we would send money for making the details after we agree upon the concrete desiign?

I think my design in Reply #305 is simpler, only one wheel on each stator piece to do the lifting and down puch
no wheel on the rotor no bevel on each stator piece only a up ramp a down ramp and hold down on the rotor (motor) cap.

I have Minilathe and CNC Router.  I use them to make prototypes (wood - aluminum). and I do not need any money to build one.  Idea is to build as many prototypes as possible all with different ideas which are shared here on the forum.  This way there is a better chance to have one working. Is there anyone else who could build prototype?  I think there is a way to build one without using lathes and milling machines.

I agree, avoiding beveling is a big relief. The ramp has to be done very carefully, though. Your ramp is the crux of the matter.  In your design there still will be a motor cap pushing on the small wheels mounted on the top of the stator magnets. Your motor cap is much simpler to make (a circle with just this much opening on one side).

Let me mention also about the HD which I prefer before the CD 'cause it's sturdier. My HD has aluminum casting which is very hard to do anything with and is surrounding the disc - disc is simehow dipped in this aluminum shell. Anybody with exerience with these HD's? Probably we should agree on a certain diameter of the HD disc as well.

That'll be great but I'm not sure we can do without if precision is sought for. I think precision is of the essence in this project.

Another question. Do you think the RadioShack rectangular magnets (with a central hole) will do or different kind of magnets should be ordered? I'm measuring those RadioShack magnets with a teslameter and am finding quite a bit of  discrepancy among them. I guess, however, that wouldn't matter in this particular construction.

Also, someone was asking how many should the stator magnets be? Recall Torbay has 16 in the first ever picture we discussed. Should we go for that or they should be less and how many. I may be a little ahead with this but maybe it's not bad to have this question in mind even at this stage of the discussion.

if you decide to use neo's in this motor...    http://www.magnet4less.com/      ... has the least expensive magnets I have ever seen. I have  never purchased from this company(so I cannot vouch for their delivery time or magnet quality), but I  plan to in the near future. If you are going to have like facing poles, radio shack magnet will be much more apt to demagnitize quickly.

Feb2006, OK that looks good to me.
