In fact, pneumatic systems and electric systems are not mutually exclusive. Pneumatic actuators can simply realize rapid linear circulation movement, simple structure, convenient maintenance, and can be used in various harsh working environments, such as explosion-proof requirements, dusty or humid conditions. But in situations where the force is rapidly increasing and precise positioning is required, an electric drive with a servo motor has advantages. For applications requiring precise, synchronous operation, adjustable and prescribed positioning programming, electric drives are the best choice. An electric drive system composed of a servo or stepper motor with a closed-loop positioning controller can supplement the deficiencies of the pneumatic system Place.
Various systems in modern control are becoming more and more complex and more sophisticated, and not a certain drive control technology can satisfy the multiple control functions of the system. Electric actuators are mainly used in applications that require precise control. The requirements for flexibility in automation equipment are constantly improving. The same equipment is often required to meet the processing needs of different sizes of workpieces. Accurate control or synchronous tracking of running speed and torque is impossible with traditional pneumatic control, but electric actuators can easily achieve this type of control. It can be seen that pneumatic actuators are more suitable for simple motion control, while electric actuators are mostly used for precise motion control.
