How the Servo Motor Works

A servo mechanism is an automatic control system that enables an output controlled amount of an object to follow an arbitrary change of an input target (or a given value). The servo is mainly positioned by pulse. It can be basically understood that when the servo motor receives one pulse, it will rotate the angle corresponding to one pulse to realize the displacement. Because the servo motor itself has the function of emitting pulses, the servo motor has every When an angle is rotated, a corresponding number of pulses are emitted, so that the pulse received by the servo motor forms an echo, or a closed loop, so that the system knows how many pulses are sent to the servo motor, and how many pulses are received at the same time. In this way, the rotation of the motor can be controlled very accurately, so that accurate positioning can be achieved, which can reach 0.001 mm. DC servo motors are divided into brushed and brushless motors. The brush motor has low cost, simple structure, large starting torque, wide speed regulation range, easy control, maintenance, but inconvenient maintenance (replacement of carbon brushes), electromagnetic interference, and environmental requirements. It can therefore be used in cost-sensitive general industrial and residential applications.
