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 ...

Every encoder-based motion-control axis, such as a servo motor or step motor, must know where it is to be accurate. If it doesn’t, it will never reach its target position. But the encoder must first ...

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 ...

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 ...

Thanks to the smooth-running precision linear guides with crossed roller bearings, the linear stage is particularly suitable for scanning applications with constant velocity. The anti-creep system ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

Where aggressive environmental and challenging production conditions combine to put the most demanding stresses on control systems the functionality, durability and reliability of the components is ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...
