MSD: What are the advantages of servopneumatic control over other alternatives? JR • Enfield: Aside from the familiar pros and cons between hydraulics and pneumatics in general (such as force ...

One thing engineers learn very quickly about position control systems is that they are inherently unstable. Consider a typical closed-loop system, consisting of a motor, current amplifier, and ...

In some categories of motor drive applications, users have little or no tolerance for unpredictable, uneven, or irregular motor behavior. While this certainly cannot be said of all motor-driven ...

They are installed not only in electrical linear motors, but also in pneumatic, hydraulic, ball-screw or power-grip belt drives and wherever high-accuracy, dynamic positioning tasks must be performed.

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

It’s long been known that a reactive approach to industrial control system maintenance is not an ideal strategy. Working from a reactive stance, in which problems are corrected as they occur, results ...

Upgrading automation systems can often extend the life of power generation facilities by decades while reducing downtime, improving operations, and reducing required maintenance. The Maggotty plant in ...
