Replications of the OC MPMM Magnet Motor, and open source project.
Several people are working on replicating this effect. As those are completed, we invite you to link to them or report them here. This is a publicly editable site, so all you need is a user/pass, and you can create a page reporting your replication.
There are several progress reports at OverUnity.com (http://www.overunity.com/index.php/topic,3871.0/topicseen.html); including compilations of dimensions and materials required.
Replications
Overview
- OC MPMM Replications (http://www.youtube.com/watch?v=NmQf1Yp-Tig) 4:30 minute video reviewing the phenomenon and featuring the replication process while we're all still waiting for the first person to have a completed unit to test. (YouTube; Jan. 10, 2008)
Successful
Bruce_TPU (gradual acceleration)
- Bruce_TPU Replicates Turbinator's Effect - Placing a loose rotor magnet on top of the round stator magnets, and holding the stator magnets stationary, Bruce_TPU is able to achieve temporary acceleration in his magnet motor, and sometimes sustained rotation. Video evidence provided. (PESWiki; Feb. 2,3, 2008)
- (1:17 minutes)
CLaNZeR's Replication (temporary acceleration)
- Sean CLaNZeR's replication of the OC MPMM Magnet Motor - Using a temporary stator magnet configuration, awaiting arrival of the proper stator magnets, Sean CLaNZeR showed brief acceleration in his replication of "Overconfident's" all-magnet motor built by Al... As far as we can tell, this marks the first successful replication of the effect to any extent. (PESWiki; Jan 14, 2008)
- (1:34 minutes)
Bill Williams' Replication
- Bill Williams (Vipond50)'s replication of the MPMM Magnet Motor - "Today after reconfiguration of the Stator magnets to a dual bearings, I had a approximately one minute self operation of the device and maintained a constant RPM once Stator Sync occurred." (PESWiki; Jan. 19, 2008)
AuthoroldHorseface's Replication
- OS:MPMM:Replications:AuthoroldHorseface - reports "a short burst of acceleration, then a sustained speed for 10 seconds" (Jan. 14, 2008)
Omnibus' Replication
- Omnibus' Replication of the MPMM - "After the initial spin, a definite acceleration is observed, which so far still cannot be sustained as long as alsetalokin's but the effect is definitely there." (Jan. 16, 2008)
Turbinator' Replication
On Feb. 1, 2008, Turbinator wrote (http://www.steorn.com/forum/comments.php?DiscussionID=60180&page=2#Item_5):
Without going into too much detail, I had a sustained rotor yesterday evening while fooling around around with the stators; The stators were not rotating but oscillating slightly (and with a rod mag attached to each stator - like i said i was tinkering!), the rotor was hand spooled and left to run down while i was doing something else..... strangely it held at around 300rpm. I will investigate further and keep a camera handy.

Unsuccessful
JR Replication of Whipmag OC MPMM
(1:55 minutes)
- JR Replication of Whipmag OC MPMM - Replication of the whipmag or OC MPMM device (YouTube (http://www.youtube.com/watch?v=UuZdctoCJbc) February 24, 2008)
LaFonte Group's Replication(s)
- LaFonte Group's MPMM Replication - Though they've made a diligent attempt at replicating the design faithfully, they've not been able to achieve any acceleration or speed maintenance.
Douglas K. Furr's Replication
- Douglas K. Furr's Replication of the MPMM - He completed his 1.5-scale version on Feb. 5, 2008; but has not been able to get it to accellerate or maintain speed. This could be attributed to several important differences between his replica and the original, including magnet strength, device material, holding screws.
Eltimple
(3:00 minutes)
- Wobbly Stator Motor - a different take on the ocal , since wobbling the stator by hand will cause rotation it occured to me that with suitable delay , i.e. spring mass etc something might happen lol still all good fun (YouTube (http://www.youtube.com/watch?v=q_43fb2Kf3M) February 12, 2008)
Variablestatus' Replication
- Variablestatus' replication of the OC MPMM Magnet Motor - A loose variant replica only decelerates. It does illustrate rotating magnetic field interactions at a distance of a few inches. (PESWiki; Jan 22, 2008)
ZeroFossilFuel's Replication
(5:37 minutes)
- Zero's OC-MPMM replication - Crude replication, barely resembles the original. Doesn't self-run, but there are some interesting observations. (YouTube (http://www.youtube.com/watch?v=EHy_OeS8qVE); January 13, 2008)
Yada Productions Lego Version
(3:02 minutes)
- Lego WhipMag Demonstration (OCPMM) - A "WhipMag" was created for educational purpose, using nothing but Lego bricks and Lego Magnets for under $50. The configuration shown in this video was inspired by Overconfident (a.k.a. OC). (YouTube (http://youtube.com/watch?v=r4-nFd6t9xw); February 09, 2008)
- costs less than $50 to build for those of you who would like to investigate some of the principles of this intriguing device [1] (http://www.overunity.com/index.php/topic,3871.msg76365.html#msg76365)
- Lego parts sourcing [2] (http://www.overunity.com/index.php/topic,3871.msg76373.html#msg76373)
In Progress
Hydrocontro's Replication
- Hydrocontro's Replication of the MPMM magnet motor - User "hydrocontro" proposes that this counter-rotating stator design accomplishes what he observed in another magnet motor design he built which only worked if the stator were held by hand. He also observes that his MPMM replica "spins better one direction (CCW) then the other (CW)". (PESWiki; Jan. 15, 2008)

(emphasis added)
"I played some more with my HDD converted into a COAL rotor today. It takes some play to get the stator to lock into AGW rotation, but it is possible. Before I have only succeeded with this when I used my finger, but today I tried to start very gentle with the air gun. After some trial and error the wheels locked into AGW position and I could increase the rpm. The wheels lost the grip some times when I was not feeding a steady air flow, but with some more trial, I manage to speed the rotor up to a high speed. I did not use any tacho, so it will only be a guesstimate, but the speed was something like 1000 rpm on the rotor. The wheels were connecting good, and I could keep them at that speed as long as I wanted to, but after 2-3 min I let it run with no air support. Then it would not sustain the speed and both wheels started to slow down still in AGW lock.
"In support of the COAL system, I got the feeling that it did not need much air to keep the high speed. But my system got a lot of friction and the stator will run down in just a few seconds if the rotor is stopped."

Craigy
- Craigy (http://www.overunity.com/index.php/topic,3871.msg69262.html#msg69262) - "Got started on my own proof of concept. Magnets are 6mm by 12mm on a rotor i had lying around. I will cut another att the correct diameter, but without cnc that takes time. The magents are a friction fit into the slots that were cut out using a 2 flute milling bit in a vertical pilar drill." (Jan. 8, 2008)
- First test (http://www.overunity.com/index.php/topic,3871.msg70067.html#msg70067) "...got my first anti gear spin using the wrong magnets but no sustain or acceleration to report yet." (Jan. 12, 2008)
- Whipmag Reverse Gearing (http://it.youtube.com/watch?v=NZ3ss9EFQsE&NR=1) ' "The whipmag or OCAL magnetic motor is now being replicated here, its early days but this shows the rotors and stator rotating in the same direction , i.e anti gearwise" (YouTube; Jan. 13, 2008)
- Mk2 in production (http://www.overunity.com/index.php/topic,3871.msg71459.html#msg71459) (Jan. 18, 2008)
- Ocal Replication by Craigy (http://www.youtube.com/watch?v=4Oq-frOyIVI) - video of stator interaction with rotor (still doesn't have it accelerating or maintaining speed). (YouTube; January 24, 2008)

I built an ugly dirty model today. I wanted to see how I wanted to connect the rotor, etc. I learned a lot. I used PEX flex .5 ID for stator holders, and used a dremel to grind a bit for a better fit for the magnets. Bearings fit fine.
I drilled my rotor slightly off, so it has a nice wobble (I am just playing until the machined parts arrive next week, using Jason's accurate blueprints!)
From what I have seen tonight, I am confident in the truth of Al's machine. I think that it will be a matter of engineering.

Crude replica.
- OC MPMM Rep.Spinning test (http://www.youtube.com/watch?v=DWKLJlImcL4) - "The little magnet rotated 8000 CCW. The rotor run CCW 2000. The speed is 4:1" (YouTube; January 14, 2008)

"I got the parts from the shop today. They look alright although the grove on rotor is a bit bigger then the magnet. Need to find ways to secure magnet. The stator magnet fits the holder I made just fine." [pictures shown] (Jan. 23, 2008) [3] (http://www.overunity.com/index.php?topic=3871.msg72598#msg72598)

Other Replications
- photos of progress by CLaNZeR, naklaw, TheOne (http://www.overunity.com/index.php?topic=3871.90)
- naklaw Video (http://video.google.com/videoplay?docid=7040941048043834176) - shows rotation, but not self-rotation or acceleration. Doesn't try counter-rotating the small magnet in the video.
- YouTube video (http://www.youtube.com/watch?v=hyuwtp2yekQ) - doesn't show self-rotation. Doesn't show attempting to spin stator magnet in counter-gear sync like the original motor shows.
- Dusty (http://www.overunity.com/index.php/topic,3871.msg69384.html#msg69384) [blue background image below] - "I'm all ready for testing tomorrow. Everything is ready just to drop in the magnets and test away. We'll do many tests, so you will hear about it." (Jan. 8, 2008)
- SPDC forum replica (http://www.overunity.com/index.php/topic,3871.msg70409.html#msg70409) - "it was running at almost constant speed for 20 seconds, but it did not manage to gain speed, and then it slowed down a little bit, and then it ran down as normal. So my hope is to make it sync at a little higher speed and start to gain speed." (Oak; January 13, 2008, 10:05:44 PM)
- btentzer Progress (http://www.overunity.com/index.php/topic,3871.msg70450.html#msg70450) - getting parts in, building, etc. (Jan. 14, 2008)
- Axle replication (http://www.ospmm.org/forum/showthread.php?t=16) - construction complete. Ready to start testing and adjusting, over the next few days. [weeks? months?]
