Electric Actuators Enable Precise Multi-point Positioning

It is a truth universally acknowledged that electric actuators have been widely used in the automatic industry for decades, which is especially true with the automatic production lines hanks to the wide spread of the cylinder driving systems that were developed more than forty years ago. To be more specific, in the past the electric actuators were generally applied to linear motion, straight moving piece production in particular, while at present, the pneumatic actuators have become the mainstream machine in the industrial field of point to point transmission. In terms of the actuator facts, thanks to the annual growth rate of the cylinder volume in a number of countries, the emerging economies in particular, the sales of the electric actuators have witnessed robust increase and its growth rate generally exceed twenty percent per year. Up to now, the mechanical properties of electric actuators is in general a fuzzy concept in terms of a uniform evaluation standard even though such methods as the data quantification, analysis of the hierarchy and comprehensive evaluation can already by combined. Thus, it might take a long way before the mechanical properties evaluation model of the electric actuators can be fully established. At that time, a number of decision methods will be introduced to assist people in making better decisions. As a matter of fact, the flowchart of the actuator facts and selection of the evaluation methods has been studied and characterized in detail by different groups of researches across the world and the electric actuators average principle has taken place of the maximum membership principle in dealing with the comprehensive value of actuator facts. Thus, electric actuators and pneumatic actuators may share the same working demand and can even be taken as an example to verify the evaluation model, which contributes to a more effective and convenient approach in the field of actuator facts evaluation.

Electric actuators are mainly used for such applications as rotating and oscillating and the models designed for linear removal become increasingly popular in recent years since electric actuators enable multi-point positioning in a highly precise manner which can hardly be achieved by traditional pneumatic actuators. Thus, when selecting actuators, users generally have a preference for the electric actuators even though a set of sufficient data to describe the performance criteria has not come out yet, especially in the industrial automation transmission. As a matter of fact, in spite of the fact that electric actuators mechanical properties evaluation is far from perfect, electric actuators are always the wise, rational choice in terms of a mechanical solution as long as the decision-maker believes what he or she wants most is the accurate information.
