ESC (electronic speed control)
An Electronic Speed Controller (ESC) is a purpose-built device designed for controlling the speed of an electric motor. Using a specialised combination of hardware and firmware, ESCs drive motors to a commanded speed. They maintain motor speed under various circumstances, such as the dynamic load of a propeller.
ESCs are available for either brushed (DC) or brushless (AC) motors. Brushed motors are most commonly used in toy-class planes, multicopters, rovers, boats, and balance bots. Most other larger vehicles use brushless speed controllers.
The term ESC stands for “electronic speed control is an electronic circuit used to change the speed of an electric motor, its route, and also to perform as a dynamic brake.
