Working Principles of a DC Servo Motor Check out the full blog post over at https://realpars.com/servo-motor/ The working principles of a DC servo motor are the construction of four major components, a DC motor, a position sensing device, a gear assembly, and a control circuit. The desired speed of the DC motor is based on the voltage applied. In order to control the motor speed, a potentiometer produces a voltage which is applied as one of the inputs to the error amplifier. In some circuits, a
