Get the most out of brushless dc motors by specifying optical encoders. They measure finer movements than hall sensors, because their operation doesn't rely on motor phases. Brushless dc (BLDC) motors ...

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 ...

Optical encoders have been used to measure position, speed, acceleration and motion direction for decades, but now they are finding new applications where high performance and miniaturization are ...

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 DSP design approach, including hardware and software implementation for a quasi-absolute encoder. LEE WEI YAN, Applications Engineer, Avago Technologies, San Jose, Calif. A high-accuracy 20-bit ...

Optical sensors are successfully used for measurement in many areas, such as the position sensing of moving objects or the measurement of distance. The types of sensor elements used in these ...
