The OC Magnetic Perpetual Motion Machine (WhipMag) Testing

While waiting for the Stator magnets to arrive I decided to start testing.

So time for a bit of weighing and Spin Down Tests:

Quick movie below to show the difference between trying to spin by hand compared to using an airline.

ROTOR1

Weight of Rotor with Brass Axle with magnets= 199 grams

Wind Down from 1000RPM = 4 minutes

1000RPMCLaNZeRSRotor1.wmv

Weight of Rotor with Brass Axle with NO Rotor magnets= 152 grams

Wind Down from 1000RPM =3 minutes 10 seconds

ROTOR2

The Original Rotor was 20mm so I will also be testing a 20mm Rotor out of Polycarbonate and HDPE.

Rotor1 is 8mm thick so by adding 6mm dummies top and bottom I get 20mm as pictures below:

Weight of Rotor with Brass Axle with magnets= 430 grams

Wind Down from 1000RPM =8 minutes 30 seconds

I was asked if I would also do a Wind Down with Rotor2 in a Vertical Position
from jcims in this thread http://www.overunity.com/index.php/topic,3871.msg70091.html#msg70091

, so here it is:

Wind Down from 1000RPM =10 minutes 30 seconds

First Flick tests:

Decided seeing the proper stator magnets have still not arrived that I would try those small
6mm Diametrically magnetised magnets again and tape them together.
Please too say I seemed to of got it to latch :)

ummmm interesting that if I jam one Stator magnet back so it cannot rotate I can get the Latch very easly.
Video below shows what I mean.

Next a try with an Airline.

Heres some latching with 1 Stator Fixed again, 1 Stator loose and of course the latcher!.
Also in the same video latching with just 1 Stator, again using the airline.

Playing today while STILL waiting for the correct stator magnets I found that the best speed to get them rear stator to latch is 320 RPM any speed over this seems to make it very diffcult.
Then if you spin the rotor over 800RPM it looses sync.

Right another update, now the Correct Stator magnets have arrived.

I lathed down some shaft and press fitted them onto the Magnets, did crack one of them, so good job I ordered 10 , so be careful as even soft brass can do some damage!

I had to ditch the cube rotor as even with a HUGE gap they were too powerfull and it was difficult to spin the rotor.
Even now I struggle to get it upto 400RPM spinning by hand and need to maybe alter the height of the stators or increase the air gap.
As you can see by the video the latching occurs at over 500 RPM with the spacing I have. I will move them back and do more testing later on.

Still 100 other things to try yet, but atleast the building blocks are in place.

Right another update, now the Correct Stator magnets have arrived.

Now using a HDPE Rotor and Replication is getting Close to the original Spec.

Video shows trying out the New Stator Magnets, Harder to latch :(

Alot of configuring needs to be done regards heights and air gap yet.

Well after random configs and trying to hit with Pot Luck and a bloody sore finger, time for some more organised testing to start.

Interesting testing done with Standard 16 slot base.

Latching gets easier using different configs and also a DOUBLE AGW!

Started looking at the weight difference of the Stator magnets and wondering maybe this is why the weaker Stators are catching easly.

First Wind Down Tests

1.) BLUE: AGW Lock at around 410 RPM
2.) RED: With Stator no AGW attempted
3.) PURPLE: No Stator Wind Down.

Please check the forums to download Spreadsheets.

Here are two wind-downs, one with dampners, one without.

3 Stator magnets, all weighing 10g and airgap of 5mm from rotor.
I span the rotor with a airline upto 500 RPM and got the AGW Latch.
I then span it with the airline upto 1300 RPM and stopped the other two stator magnets that were spinning GW.
Here is the results:

The Weaker magnets dropped out at 800 RPM.

I wanted to see at what RPM these stronger magnets would drop out.

Now I have my new bearings arrive, some new Stator holders will be worked on today and I will repeat the test. It is a bit scary waiting for that Blu-Tac to fly off and hit me at those speeds.

I cannot believe I have had so many emails and a few YouTube comments about the noise you get from the bearings and they all seem to think I am using ropey, crap, loose bearings.

I have made the following Video to show that the way the magnets interact causes this effect on the bearings and a lot of the noise.

It is not down to bad bearings but the interactions of the magnets on the bearings, I hope this helps to explain.
