Electromechanical actuators are devices that convert electrical energy into mechanical motion. They are commonly used in various applications, such as robotics, automotive systems, and industrial machinery. These actuators can be powered by electric motors, which drive mechanisms like gears or levers to produce movement. These actuators come in different types, including linear actuators that create straight-line motion and rotary actuators that produce rotational movement. They are essential components in systems requiring precise control, such as automated manufacturing and aerospace technology, where accurate positioning is crucial for performance and safety.
