It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...
Encoders are integral parts of motor-control systems that sense mechanical motion, then generate digital signals in response to that motion. The trend today is to create smaller mechanical and ...
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.
