An electronic speed control or esc is an electronic circuit that controls and regulates the speed of an electric motor it may also provide reversing of the motor and dynamic braking miniature electronic speed controls are used in electrically powered radio controlled models full size electric vehicles also have systems to control the speed of their drive motors.
The speed set value d and the detected voltage e of the speed generated by a tacho generator is compared in the comparison amplifier block then the level of the voltage signal a is determined. Additionally many ac controls have a single phase input so this allows you to run 3 phase motors in facilities that don t have 3 phase power available.
