Actuator – Troubleshooting and repair
An actuator is a component of a machine responsible for moving and controlling a mechanism or system, for example, opening a valve. In simple terms, it is an “engine”.
An actuator requires a control signal and a power source. The control signal is relatively low energy and can be electrical voltage or current, pneumatic or hydraulic fluid pressure, or even human force. Its main source of energy can be electrical current, hydraulic pressure or pneumatic pressure. When it receives a control signal, an actuator responds by converting the energy from the source into mechanical movement. In the electrical, hydraulic and pneumatic sense, it is a form of automation or automatic control.
An actuator is a mechanism through which a control system acts to perform an operation or task. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g., a printer driver, robot control system), a human, or any other input.
