Working Magnetic Motor on you tube??

[RunningBare]

This slowing and speeding up is because of the slow/fast parts of the cycle on the stators as clearly shown by ZeroFossilFuel on youtube http://www.youtube.com/watch?v=EHy_OeS8qVE

Most people dislike his replica but He is very knowledgable and his replica is only intended to explain some of the effects seen.

Good job Lumen on your observations and methodology

Cube magnets and diametrically magnetized cylinder magnets have considerably different field characteristics.

I should have shown the stator tachometer. It is not a simple coil detecting the magnetic field, it is rotary device like a small generator that generates a voltage from rotational speed.
The specs are 7v per 1000 RPM.
The wave you see is actually the stator speeding up and slowing down as it pases each amgnet on the rotor.

@lumen

I have tried to find the relative movements between the rotor magnets and the stator magnets, and a lot of people have been speculating and making sim models about this, but with your equipment and setup you might be the first to really describe the position of the magnets.
Great work.

Is there a problem in reconciling Lumen's measurements of the movement of the stator (accelerating-decelerating) with Al's measurment of the pulsing field of the stator measured with a Rogowski coil and shown here as a pretty straightline sawtooth pattern:

I don't know enough to make a good judgement here, but maybe someone who does can comment on the two compared?

The operation of this motor is reliant on the the stator being able to vary its speed. The acceleration, and deceleration must be of a controlled nature so that the overall stator interaction is aysmetrical and we get a gain. If the stator and rotor were locked or geared together you would not get a gain. If you could gear it together but with a 30 degree null zone on the gearing this would allow the decelerations and accelerations so vital to get through the rotor field with a gain. In Al?s motor it appears he had the balance just right, and the inertia was in just the right amounts.

Therefore if the stator is too light, the stator will go too fast in the acelerations and slam into the wall of repulsion, if the stator is too heavy it won?t react fast enough and  it will slam into the wall of attraction. The trick is getting a dribble of one or the other.

In this femm graphical representation of the interacting fields we need to stay in the blue zones to escape with energy

This pretty much backs up what I have found in playing with my setup and what I wrote above.

2. Is going to be extremely hard with this setup to find the 'right' combination of magnet strength, location, friction, bearings, mass of rotor, mass of stator, etc. I have only two lengths of rotor magnets to play with .5 and .75 inches. I think Al's are somewhere in between. I would hazard to guess that even Al would have a hard time making a working second one.
