Inspired by user DadHav.

Small brushless motor from a Office machine donated by Gandalf:thumbsup:

12 poles to rewind. Magnetic configuration unsuitable for a simple build that utilizes all poles. Original circuit had at least three halls on it and a rather exotic method of windings. I'll probably replace the rotor with aluminum or acrylic. Great little find, especially if you can get a bigger one. Ive tried smaller than this and its tough for those of us with fat fingers!:D

Hi ren,

Just make a tool like a Fly Tying Bobbin to wind in tight places. So much easier.

Take care,

Michel

Will be keeping an eye on your work on this one. I have a brushless blower motor I have that is only wound on 3 coils not really sure how to wire the electronics for the other 2 sets of 3 coils.

No worries mate. The biggest issue is geometry. Matching stator to rotor in a fashion which allows for the circuit you will use. I'd love to make a list of all the motors people have discovered and modified. I've already talked to Ash about his washing machine motor he has. I'll let you know how this one goes, I can tell you now that I am reconfiguring the magnets on the rotor.
