Electric linear actuators and motors. Getting the right fit.

An electric linear actuator can outperform a pneumatic model with superior control of speed, position, and force as well as provide better accuracy and repeatability. But that superior performance comes with complexity. Pneumatic cylinders commonly are simple, easy-to-understand components, while electric linear actuators are systems comprised of a motor, controller, cables, and actuator. Plus attaching a motor to an actuator usually requires some kind of adaptor or housing.

What you need to know about electric linear actuators

Electric or pneumatic? That is the question. Or at least it’s a crucial question that control systems and machine design engineers ask early in the process of specifying a linear actuator. A pneumatic cylinder may be the best solution -- easy-to-understand, lower cost -- but then again an electric linear actuator can offer distinct advantages. It really depends on the application.

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.
