Working Magnetic Motor on you tube??

Busy day as usual this end.

Have posted First New Tacho results and movie link so you can see the latching occur.

Sorry cannot be bothered to type it all again LOL

What is the spike at about 400 rpm?

Thought: For it to keep going at top speed the stator 'push' should match the fricitional slowing of the main wheel. So it would latch, push, skip(s), latch, push, etc.

Because at different speeds and considering the friction and moment of inertia, there will be either magnetic drag or magnetic push. At the chaos point exactly mid point of the bar magnet the smallest of movements increases the speed of the stator magnet. It now becomes a question of timing between when the next bar magnet meets up with the stator and by how much the angular momentum is slowed by the onrushing bar magnet.

The key has to be the ratio of weight and magnetic strength.

Sorry just fascinated and thinking at keyboard.

@PolyMatrix,

Not a bad rumination. It appears that for the given rotor weight (most of us are trying to build very close replicas of the original) the most important factor is the ratio between the rotor and stator field strength as well as the proper form of the fields.

Hope this might be of help
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.

Exclamations represent rotor edge.
"O" represents stator

And here is a 28 second audio sample

Hey RB,

Al's scope readings show a pretty symmetrical curve, almost a saw-wave.

Are you measuring something different?

I have very little idea on how to interpret properly either measurement, but why do they not agree?

Here are the magnetic induction values in kgauss of my current cylindrical rotor magnets measured at the same place on the surface of each magnet:

4.64     -4.54
4.68     -4.50
4.60     -4.48
4.70     -4.48
4.50     -4.45
4.70     -4.57
4.67     -4.58
4.66     -4.44

Can't measure the stator magnets because it's hard to get them out of their encasements. Wonder what @alsetalokin's data from the same measurement might be. Also, it's interesting if someone else could post such data.
