| Oct 7, 2016 at 16:48 | comment | added | jms | @TonyStewart.EEsince'75 While they are completely distinct parameters, there is a tradeoff between the two: When you buy two motors of the same size, mass and design, but one is wound to a higher KV than the other, the high KV motor will spin faster and generate less torque at the same power input. | |

Added section on braking, corrected errors, spelling.

final edit, I promise :)

| Oct 7, 2016 at 3:50 | comment | added | Thomas Kirven | Thanks for the detailed explanation @jms. So if I understand correctly increasing the throttle increases the amplitude of the AC signal on the 3 motor wires, which momentarily creates a phase shift, which the esc detects (with back emf?) and then changes its frequency output accordingly? | |
