Hi Marius, i am qvision over at energetic

@ Magz,

Why are your magnet faces not facing the coil ends ?

*EDIT* Just saw Marius has asked seen the same thing *EDIT*

10 min ago i withness something that didn't belived is posible.

I have the gen coil with 3uF in paralel
The rpm arrives at around 4000rpm and stays there.
I conect the light bulb and the rmp begins to accelerate slowly with the load connected.
Around 6000 rpm i disconnect the load and the rpm starts to  increas again with an constant acceleration.
After 5-10 seconds i connect the load again and the rpm begibs to ACCELERATE LIKE NEVER BEFORE. I think i hit 9000 rpm in an matter of seconds. That realy scared me and i disconected the input power.
When i first tested the rotor(rpm without any gen coils around) I hit 9500rpm but after 7000 rpm the acceleration was really slow.
My conclusion? The 3 uF cap and the load helped in increasing the rpm

Hey Marius and Deep

Thanks.   The magnets are N48 1/2in x 1/8 diametric.  Magnetized at the rim of the dia.    N facing out.

I have had this rotor for a couple years, and has done good work for me.

Marius,  I would love to see a vid on the post you just wrote.  ;]

Actually Im jealous of your coils Marius.  ;]  you get lots of bang for your buck with those things.

You can order rolls of wire on ebay for a good price to roll your own.  ;]  The 3 drivers coils are old crossover coils for speakers to cut out the high freq, subwoofer.  The large coil is one that I had wound with wire from ebay.  I believe it was 2700ft for $35 if I recall.
