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, ...

My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

[Pete] needed a rotary encoder for one of his project so he set out to build his own. As the name implies, a rotary encoder measures rotation by encoding “steps” into electrical signals which can be ...

The monitoring of rotation can involve such sensor types as proximity, photoelectric, resolvers, encoders, and tachometer generators. Most determine direction of rotation, speed, and angular position ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

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 ...

Infineon is sampling a vertical dual-Hall sensor for detecting rotation direction and speed. Production is planned for July. The TLE4966V is claimed to be the first dual-Hall device with its ...
