Electric actuators are essential components in a wide range of industries, offering an efficient solution to the task of converting electrical energy into mechanical motion. These devices are commonly used for automating systems that require precise control, making them indispensable in applications from manufacturing to robotics. This article explores the function, types, benefits, and common applications of electric actuators, highlighting their significant role in modern industrial operations.

What is an Electric Actuator?

An electric actuator is a mechanical device that utilizes electrical energy to produce controlled motion. The basic function of an electric actuator is to convert electrical input signals (usually from a controller) into mechanical energy, which results in linear or rotary movement. This motion can be used to drive machinery, control valve positions, operate doors, or even move robotic arms. Electric actuators operate on the principle of electric motors, and their output depends on the type of motor used, whether a stepper motor, DC motor, or a servo motor. Types of Electric Actuators

There are primarily two types of electric actuators: linear and rotary. Each type serves different needs based on the movement required in a particular application.
