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 ...

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 ...

• 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 ...
