Explore the concept of negative feedback and its role in maintaining system stability across various applications.

A closed-loop control scheme is able to bring motor feedback information, such as back electromotive force (BEMF) voltage or supply current to the control system. Rotary encoding is a common mechanism ...

Encoder specialist POSITAL has expanded its line of kit-style encoders for feedback for servo and stepper motors with new models that utilize the same mounting form factor as incremental kit encoders ...

While open-loop SMLA systems are suitable for many applications, stepper motor users wanting real-time feedback on load position should consider adding encoders to their motors. Encoders can provide ...

Figure 1: Depicted is the power consumption of open loop vs. closed loop stepper systems. Consider a side-by-side comparison of a traditional, open loop step motor system and a fully closed loop ...
