"After the initial spin, a definite acceleration is observed, which so far still cannot be sustained as long as alsetalonkin's but the effect is definitely there." (Jan. 16, 2008)

Soundtrack (mp3) "Effect heard around 220-230rpm and then again at around 240rpm and much lighter at around 190rpm. The rotor is let go winding down on its own with no involvement of hands.",3871.msg74862.html#msg74862

"So far most of us have succeeded in latching the lone stator AGW. That latching was the "mistake" which @alsetalokin made which he says led him to success. Obviously, however, there something more to it because no one here can yet see the self-sustaining spin despite the AGW latch. My next step will be to exchange the current N42 rotor magnets with N38 and then with N32 ans see if this would make any difference."

"Arranged the rotor magnets just for the heck of it as NSNSNSNSNSNSNSNS and tried it with the three stators in various configs as well as with 2 and 1 stator, raising the rotor several times with washers. Rotor seems a little happier--wind down time close to 30s, stators lose rotation at higher rpm and only tremble. Now, back to the standard arrangement.",3871.msg71812.html#msg71812

"I'd like to reemphasize the points @fritz made and my reply there:,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.",3871.msg71821.html#msg71821

"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.",3871.msg71833.html#msg71833

"@CLaNZeR, Same here. I've a very similar experience to OS:MPMM:Replications:CLaNZeR. Waiting for my tachometer to arrive to get some more definitive picture of what's happening."

"Qualitatively, it appears that the effect kicks in for a few seconds and then the contraption again goes out of sync to kick in again later for a few seconds as it winds down. This needs to be observed quantitatively, though. One thing is for sure, many times the smooth wind down of a lone rotor (not surrounded by stator magnets) differs substantially from the wind down of the rotor with stator magnets placed at certain positions. Detecting acceleration during these hitches quantitatively will be most significant.",3871.msg71683.html#msg71683

I want to report that the initial experiments are very promising. After the initial spin, a definite acceleration is observed, which so far still cannot be sustained as long as alsetalonkin's but the effect is definitely there.

I will restrain at this point from posting a video or quantitative results, which I will present to you later.


Magnet Gauss

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.

Spin-down Time

On Jan. 20, 2008, Omnibus wrote:

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.
