Types of Actuators

Electric
Electric

Actuators can be categorized by the energy source they require to generate motion. For example: Pneumatic actuators use compressed air to generate motion. Hydrolic actuators use liquid to generate motion. Electric actuators use an external power source, such as a battery, to generate motion. Thermal actuators use a heat source to generate motion.

Gearing (3)

A gear actuator is a specific type of actuator that typically creates movement using a basic worm gear. This style of gear consists of a threaded screw and common toothed gear. As the screw turns, it makes the gear rotate.

• Hydraulic linear actuators operate similarly to pneumatic actuators, but an incompressible liquid from a pump rather than pressurized air moves the cylinder. • An electric linear actuator converts electrical energy into torque.

Limit and Torque Sensors (2)

The actuators are expected to operate under extreme ambient conditions, however they are generally not used for continuous operation since the motor heat buildup can be excessive. Limit and torque sensors (2) The limit switches signal when an end position has been reached. The torque switching measures the torque present in the valve.

An actuator is a type of motor that is responsible for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion.

Pneumatic Actuators : A simplified diagram of a pneumatic actuator is shown in Figure 1. It operates by a combination of force created by air and spring force. The actuator positions a control valve by transmitting its motion through the stem. A rubber diaphragm separates the actuator housing into two air chambers.
