Default CD-ROM motor questions

I've been having a play (tearing apart) some CD-ROM and fan motors with the intention of re-winding them for use in an indoor flyer. One of the fan motors I've got has 4 stators, I was just wondering if anyone could shed light on how this works?

Also, what power can the built-in controlers on the back of these motors handle?

The fan motors on computers are brushless, so you cannot just plug it up to a power source and expect it to work. As for how much power they can handle, I would say you need to look up the fan's specs on the manufacturer's website. As for the motor itself, I am not sure it will have enough power to propel the plane. The computer fans are designd to spin quietly and efficiently, not in a way to give a lot of thrust. So, they might not be the best choice. But, I am not saying they will not work, just that you will have some difficulty. I would just save myself the hassle, but not my wallet, and purchase a brushless motor and controller.

The number of statorpoles ("teeth" or "hammerheads") has to be a multiple of three. A four statorpole stator cannot be used. Don't be tempted into using the fan, it will not stand the rpm's.

Lot's of cd-rom motor building instructions, do's and don't's, tips & tricks, mandatory reading
