Power Plant Question
 

Can someone explain to me the physics behind why when you have less "turns" in a motor it can spin faster? I understand why when more wires are used, it becomes smoother, but not so much the motor turns in relation to RPM.

Short answer: Higher current draw, higher magnetic field strength of the stator [or rotor in a brushed motor], stronger opposing force reaction with the permanent magnet in the motor, more rotational speed.

As long as the ESC can switch phases fast enough, [or the brushes can maintain contact with the comm in a brushed motor] you'll get more RPM.

Don't know to much in depth. bet less turns = less wire. faster the current can travel through the motor. and also have more room in the can to put thicker gauge wire. about all i know ;) and i may even be wrong :D

Perfect, confirms what I thought, but wasn't sure about. Thanks!
