Hi Scorch, hi marius, hi konehead, hi all,
    @ Scorch
        I see you are planning to adjust one side of your stator plate, as kone suggest, pls. post future developments, keep it up!
    @ Marius
        Have you tried looking at your lokal junkshop? as romero said he got his cores from scrap computer power supply (choke coils) luckily i got some, but not all pow supply have it, so good luck on your find...
       @ All
         My rig now have 6 generator coil pairs, 1 drive coil pairs, still making coils, making bobbins is time consuming, and ferrite cores hard to find, trying to look for some, still playing with backing magnets, voltage out vs drag...
       
        Good day! Crazycut

hi all

I made a short one minute video that shows speed up with me holding a stack of magnets near the rotor of 8 all-N magnets....this gives  200rpm more, and  also lowers draw 20ma...I did lots more experiments of this not shown in video - there are 4 different postions cut out of stator plates to put those backing magnets in, on the top and bottom plates , and every time there are more bakcing magnets, it speeds up rotor even more - in a position much closer to motor coil as shown in video, gave 300rpm more, but thants not in video...what is interesting is that there are no cores, no coils nothing but backing magnets vs rotor magnet giving the speed up.. (and lower draw) ...maybe similar to howard johnson PMM is what the effect is doing - its certainly not fillipping cores since there are no cores to flip!
(except for the backing magnet sbehind the motor coils installed already in video)
the mtoor coils have bakcing magnets behind them too in the video - they give about 200rpm more speed too, and lower draw 20ma in process...I wrote a bunch of info on the video in description box if you want more info.

If this doesnt go through, type in MrDKONZEN on youtube and you can see it for sure that way  in the title there of "magnet speed up" also are some videos of music from my band the Fuckedtones, (we are all fucked) plus my elelctirc car project with 12yrold kid driving it...

One thing to consider is: Proper position for the type of bearings used.

While typical ball bearings will handle "thrust" loads; they will still tend to perform better in a "radial" load configuration and you may see an increase in RPM simply by changing the position from vertical shaft to horizontal shaft.
So, unless you are using bearings engineered for "thrust" loads, might want to consider doing all testing and adjustments with shaft in horizontal position.

Otherwise the loading on your typical ball bearing will be against the sides of the inner and outer races instead of down in the groove where there is less surface contact area and less friction. When on it's side, ALL the balls are in contact with the race (due to gravity), when upright only a few balls are in contact with the race.

Dont know if I had posted this here before. But concerning bearings....  My vids

http://www.youtube.com/watch?v=iSTfFIetYPY    Using graphite

http://www.youtube.com/watch?v=FiGjK3P7JBY    Rotor rundown pt1

http://www.youtube.com/watch?v=eVXtRSxm73g    Rotor rundown pt2

The second and third vids are 2 parts of a rotor rundown from 1200 rpm. Took longer than 10min, which YT had that time limit on the vids back then.

Notice the time it takes the rotor to slow down in the last few min of pt2..   
Sick slickness.

Hi Scorch
I'm not big fan of thrust-beaings on vertical rotating stuff  unless there is quite a bit  of weight to the the rotor, then for sure  thrust bearings should be used... 
There are skateboard/rollerblade bearings in the test machine I put videos up of, and didnt crack open the seals and put in any special lube in these like I normally will do.
The clacking noise is the threaded SS axle not tight with the bearing on top and so the slop is making the noise.
Skateboard beaing are made to handle extreme lateral pressures, since skateboarders and rollerbladers are always doing turns so they work very well in vertical fairly lightweight machines like this, infact probably better than most thrust bearing designs of similar size. (my opinion only not fact)
Best lube in the world is "protecta" (fact not opinon) - its teflon-based works super great:

they sell it in spray cans too
