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 ...

This is the first of a two-part series. Part 2 can be found here. Encoders play an integral role in almost every mechanical system that involves motion monitoring or control. There are a variety of ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...

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 ...

A high-accuracy 20-bit resolution quasi-absolute encoder with DSP-based signal processing is housed in a dc stepper motor assembly, as shown in Fig. 1. Able to operate in a temperature range between ...

Crane installations are the elephants in the animal kingdom of machinery—not only for being real heavyweights themselves, but also for performing hardest work day in and day out, often under harsh ...
