Hi Fabio,
is not simple obtain speed 400 power from CD-ROM. Normally you're int he 280-300 range.
First of all you MUST replace original ring magnet, with neod. magnets. Torque and efficiency will increase a lot. If you leave original ring, you can obtain about 15W, a lot far from 400 range.
12T I think isn't a good way to start with. RON is right. Start with higher windings number. I started with 16T and 22T 0,4mm.
At the moment, I'm in the way to Test a CDmotor for 3Lipo in the 40W range, and now there are 32 T (very difficult to stay in).

Bye,
Anfarol
