Electronic speed controllers AKA (ESC) where power from a battery is directed to the speed controller and it precisely times pulses that are sent via three wires to parts of the rotating stator. By sending pulses on the three different wires we can get the motor to turn and, if we change the order of any two of the three wires we can get the motor to turn in the opposite direction.
