All motion control systems aim to maneuver loads down paths with a predefined motion. If this intended motion is achieved by comparing actual load motion to desired motion and then making corrections, ...

Fan control is an important aspect of system architecture. Though often left as a secondary activity, its implementation has significant effects. Customer response can be immediate to factors such as ...

Step motors are popular first and foremost because they are easy to use. They do not require an encoder to maintain their position, and unlike DC brush or brushless DC motors when used for positioning ...

Closed-loop circulating provides pressure control in many drilling and completion applications for which conventional fluid return systems are inadequate. Flexible and scalable to the task, these ...
