It’s easy to take feedback devices for granted. However, the impact this seemingly minor component can have on a system’s accuracy, performance, reliability, and ease of integration is hard to ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

The right feedback sensor is a key in motion systems that do what they are supposed to. Incremental disks are simple, having only one track shared by two sensors. The sensors are mounted so their ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...
