A brushless motor uses a pulsed current that alternates between three wires. This fact about them can make it seem confusing about how to make one. There are a few different ways to wrap a brushless outrunner, but I will show you the easiest and most common way. Once you know how to wrap a brushless motor you can change the performance of your motors to have different outputs such as higher torque, higher RPM, and higher tolerances. You have a few different options when wrapping the coils of wire on the stator. More wraps or turns around each pole gives the motor more torque and a lower kv (rpm per volt). More turns will allow the motor to turn a bigger propeller, and fewer turns will limit the torque so it can turn a small prop at high speed. You can use any guage of wire that will fit the motor and you can wrap multipule wires at once for better performance.
