When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

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 ...

Open-loop stepper motors have held a prominent position in automation applications over the years due to their simplicity, excellent positioning, and low cost. However, as manufacturers utilize faster ...

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 ...
