Electric actuators are devices that convert electrical energy into mechanical motion. They are commonly used in industrial and commercial applications to control the movement of valves, dampers, and other mechanical systems. Electric actuators are preferred over pneumatic or hydraulic actuators in many applications due to their ease of use, reliability, and cost-effectiveness. Electric actuators come in various types, including linear actuators, rotary actuators, and multi-turn actuators. Linear actuators are used to move objects in a straight line, while rotary actuators are used to rotate objects. Multi-turn actuators are used to control the movement of valves that require multiple turns to open or close. Electric actuators are powered by electric motors, which can be either AC or DC. The motor is connected to a gearbox, which converts the high-speed, low-torque output of the motor into a low-speed, high-torque output that can be used to move the actuator. The gearbox is connected to a lead screw or ball screw, which converts the rotary motion of the gearbox into linear motion. Electric actuators are controlled by a control system, which can be either manual or automated. In manual control systems, the operator uses a switch or lever to control the movement of the actuator. In automated control systems, the actuator is controlled by a programmable logic controller (PLC) or other computer-based control system.
