DIY Assemble 2205 2-4S Brushless Motor
#1
Hi guys, I came across this diy motor just now, and it got me thinking, sorry in advance for my ignorance!

When you wind motors, you put say 10 CW turns on one pole before putting 10 CCW turns on the next pole, yeah? The windings each create a North or South electromagnetic pole depending on the CW or CCW wind, and the direction the current flows? 
More turns, more torque, more amperage draw and the lower the Kv, right? The less turns, the faster each signal completes its circuit giving higher Kv or RPM, but the lower the magnitude of EMF on each pole, so less torque and less amperage draw.   


So I was wondering, if you were to wind 5 turns on each pole, then continue another circuit putting another 5 turns on each pole what effect would this have?

Brushless three-phase motors are a complex subject. The key to understanding windings is in the 'three-phase' bit.

Most motor windings are either a delta or wye arrangement:

   

These windings need to be wound onto the stator's poles in a specific order so that the ESC can fire the correct coil at the right time.

If you really want to dig into wiring schemes and how brushless motors actually work, here are a few links that will help you learn more.
