Hand winding is usually refered to in larger scales. When a motor is handwound you are able to wind it more efficiently, where as a machine wound motor is wound sloppily, less effeciently, but is much cheaper to mass produce. In both machine wound, and hand wound motors are available with custom stranded wire, and various numbner of turns.

In response to Son_Gokou's findings, I discovered this and posted it on TRC last year. Tomy motors have a metal armature, where as many of our after market high RPm motors are coreless, hence the higher RPM/lower torque characteristics, due to less magnetic material. Coreless means the magnet is on the inside, and the coiled wire spins around the magnet, as opposed to a traditional motor where the armature spins inside a pair of magnets.

so is it possible to handwind these motors, or the motors to small to do it, and it works better to handwind Xmod motors right?

It's is possible in theory, but these motors are too tiny to work with really.

I had a bit motor once that I managed to pull apart and get back together. So I pulled it apart again, and pulled a couple winds off each section of the armature, and resoldered the ends, but I couldn't get the motor back together again without crushing the brushes. So wrote the first time off as luck, and that's an experiment I'm done with. Easier to just buy a Perfection motor than go through all that hassle.
