This post explains for the controller. A DC rotational velocity controller, also known as a DC motor speed controller or DC motor speed regulator, is a device or system used to control the speed or rotational velocity of a DC (direct current) motor. DC motors are commonly used in various applications, and controlling their speed is essential in many industrial, automotive, robotics, and electronic systems. DC rotational velocity controllers are employed to achieve precise control over the motor’s speed, direction, and torque.
