Definition: The word "actuator" refers to a device that can be used to change the physical state or behavior of an object. It is often associated with mechanical components, such as valves, actuators, and sensors. A typical actuator consists of a shaft (motor), a clutch, and some mechanism or control system. The shaft (motor) delivers a force or movement to the actuator, while the clutch engages the motor at certain points so that it can be turned on and off, typically by moving through an axis in the actuator. The mechanisms or control system used with an actuator allow for precise control over the physical behavior of the actuator. These systems include sensors (like pressure transducers), actuators (like valves), and other components such as actuators, motors, and a controller that can be programmed to operate according to certain parameters. Understanding the operation of an actuator is crucial in a wide range of applications, from industrial processes where safety and reliability are critical, to healthcare systems where patient comfort and autonomy are important.
