Absolute encoders using optical technology often face limitations in resolution and size. For example, to achieve a higher resolution of up to 16-bits, the absolute encoder has to be combined with an ...

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 ...

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 ...

Encoder tracking is a technique that monitors a reference motor with an encoder and controls a secondary motor. Encoder tracking is a technique that monitors a reference motor with an encoder and ...

This file type includes high resolution graphics and schematics when applicable. Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For ...

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 ...
