rewinding old cd-rom motors for indoor- & park-flyers
The two discussions provided in the post above, are probably, together with the three cd-rom homepages (Wolfgang Korosec, John Jackson, Satoru Sasaki) , the two best cd-rom conversion threads/links, highly informative and not that long (see the MOAT, mother of all threads 😉, that one cleared basic questions/problems and did the groundwork for the ‘one hour conversion’ threads, worthwile reading it, when you have the time). They are already part of the compilation I gave in my first post, highlighting them is a good idea.

www.aircraft-world.com now stocks magnets and cd-rom motors:
“Sanyo CD-ROM Motor - 9-Pole Stator measures 20.25mm dia, 8-plates for total thickness of 3.1mm”
Search the site for ‘magnet’ respectively ‘stator’.
I created a thread for publishing/comparing the results from the aircraft-world Sanyo cd-rom motor. Who’s first?:

You are likely to be an expert in motors. Maybe you have got a good (tested) scheme of controller and hex-codes, for a motor based on CD-rom, so that it would be possible to make the controller using that scheme? If it is posible, could you please send me such a scheme? That would be enormously helpful and I would be extremely thankful to you. It would be excellent if the scheme is based on microchip.

Not an expert, I only pass on and compile information on the subject of diy motors and controllers. For do-it-yourself controllers see:

HEX коды тоже есть для всех трех PIC-ов
А коды сбросить можешь ❓
А можно подробнее? Какие параметры, кто разработал…
Есть и датчики Холла, и BEMF…
Что-ли переключать можно?
That circuit diagram is good food for the Ezone do-it-yourself electronics subforum 😃 See:

Что-то babelfish.altavista.com - не переводит, может слишком много символов? Если удастся перевести буду благодарен 😉

А вы делали этот регулятор ❓ ОН вообще работает ❓
Народ интересовался brushless контроллерами, на PiC-ах в частности. я выложил инфу, дал ссылку на оригинал, сайт разработчика. Не требуйте от меня большего. Схему не повторял и ничего по сути предмета пояснить не могу. Sorry 😢
