Which component is crucial for converting control signals in servo systems?

In servo systems, the crucial component for converting control signals is the servo motor. The servo motor is responsible for executing the commands that it receives from the control system, which translates the control signals into mechanical motion. When a control signal is sent from the controller, the servo motor receives this information and adjusts its position, speed, and torque accordingly to achieve the desired outcome. This makes the servo motor essential for the overall functioning of the servo system, as it directly impacts the precision and responsiveness of the system's operation.

While other components, such as the controller, sensor, and amplifier, play significant roles in the system, they do not directly execute the conversion of control signals into movement like the servo motor does. The controller processes the desired input signal and determines the necessary outputs, the sensor provides feedback on the motor's current position, and the amplifier is responsible for boosting the control signals to a level that can drive the motor. However, it is the servo motor that ultimately performs the action dictated by these components.
