Actuators

Linear actuators are a key category of actuators. A linear actuator is used to produce linear motion. It has three distinct mechanical characteristics – stroke, force, and speed. Select a linear actuator and discuss its operation, characteristics, and applications. 

An actuator can be defined as a device that converts energy into physical motion. The vast majority of actuators produce either rotational or linear motion. For example, a DC motor is a type of actuator.
