plastic wheels to embed magnets

[Megatron]

I'm a newbie to the whole magnetic motor thing.  I was intrigued when I read an article posted on engadget a while back of the OC MPMM motor.  After seeing so many people fail miserably at Nicolaspelledbackwards' alleged working whipmag, I determined that it is either a total hoax or absolute dumb luck that he got the stars to align for him.. I'm betting the former, especially after seeing the video he posted of throwing the whole thing in the trash.. To me, it says "I fooled you idiots, I had my fun, have a nice life."

I was taken aback at the realization that the whipmag is most probably an unattainable dream, so I started researching what might really work.. Thats when I came up with my own original idea for a 3 phase motor..  Needless to say, a week later I stumble on the Perendev motor which is almost exactly what I came up with.

I said almost.  I have a few ideas up my sleeve and I'm ready to move on to the prototyping phase.  All I need to do is find out how you guys get your fancy whipmag and/or perendev white plastic wheels made.  I've heard terms like "high density polyethelene", etc.  but I don't know where to go to buy the resin, or blocks of the stuff, or if I have to get a prototyping place to make it for me or what..

Any help would be greatly appreciated.. and your patience & understanding of a newbie is also much appreciated.

Cheers!

The motor you are talking about OC stuffs, you can find a big thread here about it and replication with some little success http://www.overunity.com/index.php/topic,3871.0.html

Some are able to get a speed up but stop after few seconds. So the effect is real, but so far none was able to get it run like AI.

Yes its high density polyethelene, Usually you buy big sheet of that material, better to find a shop that are making them near to you, they cost a lot in shipping!

To cut them, a lot of peoples here use a CNC machine or cut it with your bandsaw for example but you will never get a result like a CNC machine!

TheOne,

I think Al's whipmag was a hoax.  That is not to say there isn't a sound principal behind what Overconfident came up with.  I think what is hurting the whipmag is the resonance within the stators.  If the stators were built with a ratcheting mechanism i.e. prevented from moving backwards, it would stop what everyone describes as the bearing chatter.  I think a lot of rotational inertia in the stators are being lost from this.  It might also be possible to synchronize the rotation of the stator with the rotation of the wheel using some kind of gearing.  You would obviously need to double-gear it to maintain the anti-gearwise motion.  Also, you might need to use an eccentric gear to mimic the stator's motion that is witnessed at low RPM's. 

Its my observation that the whole whipmag principal is based on the stator rotating to a neutral state with the wheel magnet when they align.  i.e. they both must align at mid-pole.  This alignment can only be done due to the existing rotating inertia of the stator from a previous repulsion or attraction period.  Unfortunately, with the "bearing chatter" from the stator jerking as it rotates, any acceleration would quickly diminish.

This is why I believe the whipmag would require extreme precision to make work, and at that, virtually no load could be placed on such a device.

I think a version of the "perendev", if you will, is the best way to go.  You need at least two simultaneous attraction or repulsion forces (or a combo) to overcome 1 sticky point.  That gives you lots of extra energy (a 2:1 ratio is very good!) to be sloppy with the design but still have the device produce enough work to power a small generator.  The whipmag just requires so much precision for the theory to have even a chance of working, that it just seems like wasted money compared to the relatively proven theory of the 3-rotor designs.

But getting back to my original question, do you have any idea about how much money it would cost to have 3 discs 1.5" thick x 8" diameter built?  I could bore the magnet holes myself, I just need the discs cut for me..

Cheers!

I don't know, first you need the CAD plan, then the CAD plan need to be converted to GCODE for CNC machine.

I believe its cost a lot

I am in the process to build my own CNC machine, but I cannot respond for the how its cost, I believe that depend of the CNC machine owner

Megatron,

Here is my recent experience...

If you go to a commercial place they will be extremely expensive. The rotor for the OC MPMM rotor would cost over $300 to have made at a commercial shop. The materials are cheap, a slab of plastic, probably $10-20, but the machining is expensive. The price goes up for every machining step you need.

Another choice is to get into the machining part for yourself, but setting up a nice little machine shop is not cheap either, several thousand for new equipment, less for used.

Another choice is buy the cheap materials, do the design work yourself, and find a friend with a machine shop who can make it affordable.
