Closed-loop control of stepping motors integrates feedback from position or current observers to achieve high precision, rapid response and robustness against load disturbances. Unlike traditional ...

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, ...

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 ...

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 ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...
