In fact, pneumatic and electric systems are not mutually exclusive. The pneumatic actuator can simply realize the fast linear circulation movement, simple structure and easy maintenance. At the same time, it can be used in a variety of harsh working environments, such as explosion-proof requirements, dusty or humid conditions. However, when the force increases rapidly and positioning is required, the AUMA electric actuator using a servo motor has advantages. For applications that require synchronous operation, adjustable and specified positioning programming, electric drives are a good choice, and electric drive systems consisting of servo or stepper motors and closed-loop positioning controllers can complement the shortcomings of pneumatic systems.

In modern control, all kinds of systems are more and more complex and precise, and not a certain drive control technology can meet the various control functions of the system. AUMA electric actuators are mainly used in applications where control is required. Automation equipment demands increasing flexibility. The same equipment often needs to adapt to the processing needs of different sizes of workpieces. The actuator needs multi-position control, and the running speed and torque should be controlled or tracked synchronously. These are not possible with traditional pneumatic control, and the AUMA electric actuator can easily achieve this control. It can be seen that pneumatic actuators are more suitable for simple motion control, while AUMA electric actuators are mostly used for motion control.

AUMA electric actuators are broadly defined as: a drive device that provides linear or rotational motion. It uses some driving energy and works under the action of some control signals. Actuators use liquid, gas, electricity, or other energy sources and convert them into driving actions by means of motors, cylinders, or other devices. The basic types are partial turn, multi-turn and linear drive modes.

The basic actuator is used to drive the valve to the fully open or fully closed position. For controlling valves, the valve can be precisely positioned in any position. While most are used to open and close valves, today's designs have gone far beyond simple open and close functions. They include position sensing, torque sensing, electrode protection, logic control, digital communication modules and PID control modules, all housed in a compact housing.

In industrial production, AUMA electric actuators are widely used. It is composed of two parts: the actuator and the regulating mechanism (valve). It is not difficult to see from the literal meaning that it is driven by electricity, so as to achieve the role of remote control of the valve, without personally opening and closing the valve, which is convenient and ensures personal safety. Advantages: easy access to energy, sensitive action, fast signal transmission speed, suitable for long-distance signal transmission, easy to use with electronic computers. Disadvantages: Generally not applicable to fire and explosion-proof occasions, and complex structure, expensive.
