Brushless servo motors – more control for valves with linear actuators

Process industry engineers are looking to more sophisticated motion control solutions for valve automation because of an ever-growing need to improve productivity, increase efficiency, and minimize downtime.

These engineers must control the valves that regulate the flow of materials throughout a facility, and there are two basic ways to control these valves: linear motion (rising stem) and rotary motion (half turn or quarter turn). Powered rising stem valves are often used in mission-critical areas of a process. In these applications, reliability, repeatability, accuracy, and responsiveness are crucially important. These factors impact the type of valve actuation specified. There are traditional methods: pneumatic or hydraulic actuated systems and electric linear actuators driven by brush servo motors. Then there’s an emerging technology: brushless servo motor driven electric valve actuators.

Something completely different – unique electric linear actuator applications

We all recognize that linear actuators are critical and much-used components in industrial automation systems.  They’re at the heart of many machine tools, conveying configurations, and packaging systems.  But what if we look beyond those industrial uses?  Here are a few unique applications our actuators have found themselves in.

Mechatronics, electric linear actuators and control system design

If you’ve been around engineering, you’ve probably heard the term “mechatronics” used to refer to a design process that blends mechanical engineering, electrical engineering, telecommunications engineering, control engineering, and computer engineering. Mechatronics is a multidisciplinary approach that rejects splitting engineering into rigidly separate fields. Originally, mechatronics just included mechanics and electronics; however, as technical systems have become more complex the word has been broadened to include more technical areas.
