An electric actuator is a device that converts electrical energy into mechanical motion. It is commonly used in various applications, such as robotics, industrial machinery, and automotive systems, to control movement and position. Electric actuators can be linear, providing straight-line motion, or rotary, enabling circular movement. These actuators are favored for their precision, speed, and ease of integration with control systems. They often use motors, such as DC motors or stepper motors, to achieve the desired motion. Electric actuators are also more environmentally friendly compared to hydraulic or pneumatic systems, as they do not require fluid power.
