Engineers using an incremental encoder for the first time often have a misunderstanding about what types of signals are provided by an encoder and how to interface an encoder to their application.

Rotary encoders provide critical information about a motor shaft’s position, rotational direction, velocity (rpm), and acceleration. They are vital components in motion-control feedback loops used in ...

The quest for energy-efficient designs has made capacitive position encoders a hot topic. • The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize ...

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 ...

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 ...

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 ...
