What component converts an electronic signal from the feedback device to the servo valve in a servo system?

In a servo system, the component responsible for converting an electronic signal from the feedback device to the servo valve is the torque motor. The torque motor operates by receiving an electronic signal indicating the desired position or speed and generating a corresponding mechanical output. This output is then used to control the position of the servo valve, ensuring accurate positioning of the actuator or the load being controlled.

Torque motors are typically designed to provide high torque at low speeds, making them well-suited for precise control applications. By translating the electronic feedback into mechanical movement, the torque motor plays a crucial role in maintaining the stability and responsiveness of the servo system.

Other components listed have different functions: encoders measure position or speed but do not convert signals to a servo valve, transducers convert one form of energy to another, and tachometers measure rotational speed but are not directly involved in signal conversion for control systems. Understanding these distinctions is essential for grasping the operation of servo systems in a millwright context.
