Data collected regarding the OC MPMM Magnet Motor

An open source project.

Contents

Data

Nikolabackwards / Alsetalokin

The person who build the first device, shown on YouTube, which launched this whole open project, has done quite a bit of testing.

Acceleration Audio

(32 seconds)

  • Peak Frequency Analysis of OCPMM acceleration - A visual audio file of the acceleration in Alsetalokin's first video, during the last portion of the video in which he holds two of the stator magnets stationary. (YouTube; January 10, 2008)
  • Spectrum analysis of Al's first video "I sampled Al's video three times at two different places, for a total of six samples as shown in the figure .... Three analyses were performed for self-sustaining rotation at 1700 rpm [three rotating stators]. Another three at 4700 rpm -- after acceleration [one rotating stator]. I've included some basic observations in the figure below. Al's voice-over didn't make this easy." (Yadaraf; February 04, 2008)

Run Time

Nikolabackwards has run a number of tests, observing gradual slow-down. On Jan. 11, 2008, he ran an endurance test, in which the device ran for 7 hour 27 min, at which point he shut it off so he could go to sleep. At the end of the test, the RPM was: Rotor 1257, Stator 5030

Two Steorn Forum posts regarding this test:

About magnets

"I have done some rough strength measurements on the rotor magnets (I got them from a surplus store in downtown TO, and I think I got the last 20 they had). They are nickel-plated NdFeB's with estimated energy product 35-40 MGO. The field viewing film doesn't reveal anything obvious."[1]

Rotor-Stator Speed Ratio

Appears to be 1:4

There is a good link on this at OverUnity.com showing Al's data, and the ratio between stator speed and rotor speed over a range of speeds.

I did a count by hand a found that the stators rotate four(4) rev's/ one(1) rotation of the rotor.

Hand spin up with one Stator in Sync and the other Two stopped.

Rotor RPM - 667
Stator RPM - 2230
R = 3.348 to 1

Second Attempt
Rotor RPM - 736.3
Stator RPM - 2542
R = 3.4523 to 1

I used my sound card and constructed a transducer consisting of a ferrite core and around 20 turns of copper wire, the measurement is taken approximately 1 inch from the stator while I maintained AGW lock by spinning the rotor manually.

What your seeing is 2 cycles of the stator.

No-Stator Run-Down Time

Seems that the original positioning with the three stators and two almost opposing stators give better results. Here are some very preliminary results I just obtained for the original 3 stators positioned as in the video. When rotor spun by hand (no AGW attempt) average spin down time of five attempts is around 15s. Same initial spin (~300rpm) with successful AGW of one of the stators (the leftmost from the video), the two other stators held non-spinning, average spin down time for five attempts around 35s. Again, these are just preliminary results.

Spin down time of a lone rotor (no stators) -- about 220s.

Rotor-Stator Interaction


(4:57 minutes)

  • Stator magnet is repelled from turning rotor, when the stator magnet is not in motion. When stator magnet gets in sync, it is drawn to the rotor.
  • Mock Up Vid 1 - In validating some of the scope traces and sync ratios I slapped a workable test rig up out of spare parts I had laying around. AGW sync is shown. (YouTube; January 15, 2008)
  • Harvey's explanation at OverUnity.com
  • Mock Up Strobe Stills 1 - Harvey provides slide show of still shots from stroboscopic lighting. (YouTube; January 16, 2008}

Magnetic Sensors

On Jan. 20, 2008, fritz wrote:

I have some experience building magnet sensors using Philips/NXP:

KMZ10A +/- 0.5kA/m; = +/- 625uT
KMZ10B +/- 2kA/m; = +/- 2.5mT

This stuff is probably way to sensitive - but using it in a metal core as shunt can give nice sensors.

If somebody is interested, pls. contact me.

Anyway, using a spring gauge to check attract/repell forces is a very easy way to match the magnets.

Another idea would be a setup to degrade magnets with a strong m field, checking the field after every degrade cycle to achieve exactly matched magnets.
