A fail safe electric actuator is a device used to control the motion of a machine or system. It is an electromechanical device that converts electrical energy into mechanical energy to move or control a mechanism or system. It is a device that is designed to ensure that the system will remain in a safe state in the event of a power failure or other failure. It is commonly used in industrial automation, robotics, and other applications where precise control of a system is required. Fail safe electric actuators are designed to automatically return to a safe position when power is lost, preventing the system from going into an unsafe state. This ensures that the system remains in a safe state even if the power is lost, thus preventing potential damage or injury. Fail safe electric actuators are reliable, durable, and can be used in a variety of applications. They are an essential component of any system that requires precise control and safety.
