It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...

Rotary encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...

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 ...

This application note demonstrates how to read data from the two-channel output of an incremental rotary encoder. Data from these two channels are based on the Gray Encoding System and can be used to ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

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 ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

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 ...
