There are several types of servo motors, each with its unique characteristics and applications:

The control unit (such as an Arduino, PLC, or microcontroller) sends a high-frequency electrical signal in the form of a pulse width modulated (PWM) wave to the servo. There are several types of servo motors, each
Servo motors operate using . The angle of rotation is controlled by the duration (width) of pulses applied to the control pin. A continuous stream of pulses is sent every 20 milliseconds, with pulse widths typically ranging from 0.75ms to 2.25ms controlling the full range of motion. The servo constantly compares the potentiometer's voltage with the incoming PWM signal to adjust the motor and reach the desired angle. A continuous stream of pulses is sent every
Controlling flight surfaces (flaps, rudders) in drones, airplanes, and satellites.
High efficiency (only consumes energy required by the load). High output power relative to motor size and weight.
