"RICK'S PIPE DREAM" Magnetic Motor-Generator

[Michelinho]

Hi rickoff,

Have you seen those arc magnets from All Magnetics Inc?
Surplus Magnets -- We have surplus magnets in stock include Alnico magnets, Ceramic Magnets, NdFeb Magnets, SmCo magnets
They are not magnetized but available. May be they can magnetize them the way you want and with a ceramic water cooled saw make them the width you want. May be sell some to members.

Take care,

Michel

Hi Michel,

Yes, I have seen those but was not interested in them since they were ceramics. Neodymiums are definitely needed to create a magnetic motor capable of performing any truly useful work. Neos are very difficult to remachine without damaging them, so the only viable option is to either buy currently available shapes and sizes or have them custom manufactured. Thanks for the suggestion, though.

Best wishes,

Rick

Rick, I'm a (former?) cyclist. Maybe my parts bin has the sprocket for you. Please specify and I'll look for you. I'd be honored to be of any use. Naturally it would be on me.

And, thank you for the elaborate answer.
If is no surprize that at a short radius (axle thickness), a wheel is hard to stop. If you can obtain sufficient displacement from that thin axle, who know, it may do wonders for your purpose.

Regards,
J

Hi J,

I'm looking for a standard single sprocket for rear wheel. My axle has a 1.375" thread (1 + 3/8") for the sprocket hub.

Yes, like I said, I only need about 1/4" of rapid movement by the cam. If I only use half the available force in order to move a little on the early side then the payoff in repulsion force will more than make up for it.

Ah, threaded sprockets are a bit old fashioned, I don't have a collection of those I'm afraid. Make sure to differentiate between "cog" and "freewheel". The latter has bearings build it, the former is more commonly used on track bikes, where cranks are always turning when the wheel is.

Do them a useful favour.

I'd love to try out a pair of these, but really couldn't think about it unless I could get them for the $37 price

Why not write to them explaining that you are involved in what may
well become a cult viral type Youtube promotion, and that if they
supply you free of charge with what you need, their web site will be
painted on the side of the apparatus.

Hi Paul,

Thanks for your suggestion. I did explain to the manufacturer that if a pair of these magnets proved to be as useful as I suspect, then orders for hundreds of these would likely follow. So I was hoping they would offer the first pair either free or at a nominal charge, but that didn't work. I didn't want to go into detail to them about what these would be used for, since I figured it would cause a red flag to go up and perhaps make it impossible to obtain these. Actually, I had to keep hounding them just to get a reply, and was beginning to think they were purposely avoiding a response. They kept telling me that they were looking over my drawing and would ge back to me in a couple of weeks with a quote, and that went on for 3 months. I'll make another effort to convince the manufcturer that it would be in their best interest to help me out, but based on their past responsiveness I'm not that optimistic about my chances.

Now I'm wondering about the process they actually use to manufacture these bonded, shaped neodymiums, and whether or not we might be able to duplicate it somehow. Perhaps someone could research that possibility and write about it here.

Best regards,

Rick

Hi Cloxxki,

A freewheeling sprocket is what I'm after. You may have noticed that, in post #278, I had suggested the possibility of utilizing the ratcheting click stops as timing adjustments for the cam. These sprockets are quite common on inexpensive bikes that end up at recycling centers and scrap yards. Hopefully one will come along soon here, either at the dump or in the mail.

Best to you,

Rick

Just a thought on the printer.....

If it is not doing so well then maybe a recycled one could be found somewhere......like at one of the used computer stores.....

Hi TJ,

At some point in time the Dell Laser MFP 1815 printers will be easy to come by. It would be interesting to pull the magnet from one and see how it was magnetized. Dell had no information available concerning the magnetization. It must be axially magnetized (north and south pole at opposite ends) to be of use to us. If anyone reading this is able to find one, please let us know the pole orientation.

Best regards,

Rick

I remember reading the interview with Howard Johnson.

His motor was built so the armature was stationary, and the stator rotated around the armature. You have that part correct.

However, the threaded rod is not for tightening the bearing. It is to draw the armature into the stator, and, therefore, obtaining rotation. The more the armature is drawn into the stator, the faster the stator rotates.

This was designed to be able to apply more magnetic forces, to maintain proper rotation speed, as in a larger draw from the generator.

He tried to get GM to look at the design, and utilize it in an automobile.

The movable armature was the "throttle" to maintain speed of the car.

I remember seeing curved magnets, and, my computer was acting up, so I didn't get the bookmark applied correctly. I will do some searching.

I have also read, it is possible to cut neo dymium magnets with a diamond saw and LOTS of coolant. The dust IS flammable.

Reply to Harold:

Hi Harold,

You are quite right about the functionality of HJ's knurled knob, and I have corrected that description in post #274. Thanks for pointing that out. When first writing that post, I only remembered that it was the speed control. Of course moving the magnets into or out of direct alignment is a very effective way to adjust rotational speed, and is far more preferable than creating tension on a bearing. Either method would work, but there's no point in utilizing an effect that would cause premature bearing failure when it isn't necessary.

Yes, it is possible to cut neodymium magnets. The hardness of these magnets (RC46 on the Rockwell Hardness Scale) is harder than most cutting tools, and that is why diamond saws or abrasive wheels are needed for cutting. If the magnet heats to 176F degrees or above during machining, it will lose some of its magnetism, so slow and intermittent cutting with lots of coolant is the only way this can effectively be done. Most folks aren't going to have such equipment and methods available to them, but an enterprising individual might be able to cut and shape magnets for others and turn a nice profit while doing so. It depends upon the demand factor, and once you can demonstrate a working and efficient magnetic motor then of course the demand factor would soar.

Thanks again for your post, Harold, and best regards to you,

Rick

HJ magnet shape?

Hi Rick,

Is your interest in these HJ magnets for a pipe dream build as is, or would you be attempting a HJ replication?

Is it the shape of the magnets that is so desirable?
Is it the strength?
Do you believe that the flux fields are focused because of the tips?

Sorry for all the ?s, but I believe I could construct a small wooden, arch shaped saddle out of thin bass wood window blind slats, that could accommodate a stack of rectangle neo magnets, with wood shims between to form the arch shape. If the tip shape is a key to performance, might iron be ground to that shape and attached to ends of the neo stack create the same effect?

I will attempt to post a pic or two of my PMM bike wheel test set up, today if time permits.

Tomorrow I will check with the computer recycling center here for the MFP 1815 printers, and will let you know if I have any luck. They have a large warehouse full of all kinds of stuff. The sparkies here would have a field day at this place.

best regards,
Gene

Hi Gene,

Yes, I would like to try these magnets out on the Pipe Dream apparatus. The particular size and shape of these magnets definitely makes them very desirable. The curvature is an absolute must for anyone attempting to replicate HJ's magnetic motor design as shown in the color diagram of post #274. I believe it would also be quite advantageous positioned over a level array of magnets such as utilized with the Pipe Dream apparatus. Because of the curvature, and the narrowed ends, the field strengths are in fact focused to great advantage.

No, shaping iron tips at the ends will not work. That's because the rotor magnets will all, regardless of polarity, see the iron as an attraction.

The MFP 1815 laser printer magnets are shaped and sized just the way we want, but remember that it is unknown how these are magnetized. Arc magnets are most commonly magnetized radially, through the thickness, and that is not what we need. We require them to be axially magnetized, with the poles at the ends. So be sure to take a compass or small magnet with you when you go hunting.

Best 2 U,

Rick
