Technical Field

[0002] An electric actuator is a driving device that can provide linear or rotational motion. It uses a certain driving energy source and works under a certain control signal. The split electric actuator includes a driving part and an execution part. The driving part is usually composed of an electric motor and a reducer. The electric motor is responsible for providing power and converting electrical energy into mechanical energy. The reducer is used to reduce the speed of the motor and provide a greater torque output to meet the working requirements of the execution part. The execution part selects the actuator according to the specific application requirements. It can be a linear actuator, a rotary actuator or other types of actuators. The execution part is responsible for converting the power of the motor into a specific form of motion to achieve the required working function; for example, a linear actuator can achieve linear motion, and a rotary actuator can achieve rotational motion.
