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 ...

• Clever management of motor current in a closed-loop stepper system can eliminate problems around resonance points and reduce motor noise. • Judiciously managed stepper motors can easily compete with ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

The AlphaStep AZD-K Stepper Motor Drivers offer 24/48 VDC input voltage, high functionality and closed loop control. Automation World covers the entire spectrum of industrial automation technologies, ...

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 ...

Stepper and servo motors have different attributes when considered for motion applications. Torque curves play an important role in selecting the proper size and type of motor for an application.

You have a project that needs something to move. Should you use a stepper motor or a servo motor? [Matthias] has an opinion, and you can hear his thoughts in the video below. One tip we’ll take away ...
