Working Magnetic Motor on you tube??

[Omnibus]

I'd like to reemphasize the points @fritz made and my reply there:http://www.overunity.com/index.php/topic,3871.msg71709.html#msg71709 Proper form of the magnetic fields is of crucial importance in all these motors. Very hard to achieve. I'm looking now at one of my ostensibly (on the face of it) exact replicas of @alsetalokin's motor. Supposedly, when slowly turning the rotor the pattern one observes when the rotor is let go form a maximum to maximum (one feels these maximums when turning the rotor slowly by hand) should be of the same form repeated four times. Not so in my case. I'm observing the stator equally outstanding from the other two. If I start with a rotor magnet facing that stator the rotor bypasses the next magnet and bumps into the barrier formed by the third one. If I, however, continue and let go the rotor, further clockwise, from that barrier on the rotor stops at the fourth while it should bypass it if the pattern is to be preserved and so on. There's only one other place where the initially described pattern is observed, although slightly different (intermittent accelerations appear different). Now, that may be a significant problem. I've ordered more of these cylindrical magnets and will try to find matching ones to see whether this picture will improve. Of course, the stator magnets should be matching too. Wonder if someone else would be willing to check his rotor in this fashion.

Hi,
This might be very good news.

If my latest FEMM simulation is for real, it might give us the information we need.

It shows how we can get a positive torque for both the rotor and the stator.

Before I get too carried away here, we need to wait with the champagne till this has been triple checked.

It shows that the stator needs to deviate from a constant speed to get a gain. In this simulation this is taken to the extreme where the stator almost stops at the close passing of the rotor magnet, and gets maximum acceleration. As speed picks up the momentum of inertia increase and the torque from the magnets will give less change in speed. This will give less extra torque, and the power gain will be less.

So with a stator with high mass or momentum, it will be more easy to get into AGW locking, but the inertia will soon be too high for further increase in power. With a lighter stator it might be difficult to start, but at higher speed it will still fluctuate and give better torque.

Personally I thought my stator was too light, so I put lead inside it. It helped in getting a more easy AGW lock, but I do not see the OU any more. The first day before I added the lead, I had a gleam of what Al might have felt when his rotor started to spin by itself.

So maybe I will remove the lead and see if I still can get an AGW lock.

@sveinutne

When looking at my device it appears that all the conditions you found favorable are in place. The stators indeed come to a stop at some points and then accelerate thus deviating from constant speed which should make them get a gain. Also, the weight of the stators is according to the specifications outlined by @alsetalokin. Thus, as I already said, it seems to to me now the focus should be on ensuring proper fields.

@Omnibus

Maybe there is a limit to how much ?OU? you can take out of one stator, and if your system got more friction than that it will never sustain itself.
But to me most of the friction is in the fast turning stator, so the first thing I will do is going for two bearings on the stator to keep it more in place and hopefully reduce the friction.

@sveinutne,

I was thinking of that too. It seems to me, though, first the fields have to be fixed. Even with smooth bearings and lessened friction wrong fields won't bring success. Mind you, your FEMM is based on idealized field forms.
