Problems solved by technology

Once the electric actuator in this way is installed, the speed can no longer be adjusted, which is not suitable for modern intelligent control
[0003] In addition, due to the need to adapt to different parameter requirements, the peripheral accessories of electric actuators often have a wide variety, and it is extremely difficult to replace them on site.
[0004] Traditional electric actuators generally use a combination of potentiometers and gears for stroke setting. Its structure is complex and its reliability is poor, and on-site users often cannot choose flexibly.
In terms of control functions, traditional electric actuators can only complete basic switching requirements, but cannot achieve complex judgments and operations, and do not have self-diagnosis functions
[0005] With the improvement of industrial technology, users have put forward higher requirements for the communication and network configuration capabilities of electric actuators, while traditional electric actuators basically do not have the industrial fieldbus capabilities at the international level in the late 1990s

Description

technical field [0001] The invention relates to an actuator, in particular to an intelligent electric actuator. Background technique [0002] The electric actuator is a common actuator, which can be widely used in the field of automation control. Electric actuators widely used in domestic industrial sites now generally use on-off mode to control single-phase or three-phase AC motors. Once the electric actuator using this method is installed, the speed can no longer be adjusted, which is not suitable for modern intelligent control. [0003] In addition, due to the need to adapt to different parameter requirements, the peripheral accessories of the electric actuator are often of various types, and it is extremely difficult to replace them on site. [0004] Traditional electric actuators generally use a combination of potentiometers and gears for stroke setting. Its structure is complex and its reliability is poor, and on-site users often cannot choose flexibly. In terms of ...
