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 ...

In aviation the term fly-by-wire means that the control surfaces of an aircraft are operated by actuators rather than via cables and rods, with electrical signals transmitting information from the ...

Brushless dc (BLDC) motors are used in countless applications. Many engineers today are looking to improve the performance of their BLDC-powered systems, and a new trend is emerging: An increasing ...

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 ...

Encoders are integral parts of motor-control systems that sense mechanical motion, then generate digital signals in response to that motion. The trend today is to create smaller mechanical and ...

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 ...
