A black and white paper made from a piece of printer paper and a sharpee pen are used to create the optical encoder as it keeps track of the current location by using an IR emitter and detector. A ...

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

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 ...

Alignment of optical encoder commutation signals to a Brushless DC (BLDC) motor could be thought of as being comparable to timing the distributor on a car engine. The distributor tells the spark plugs ...

A technique called dual-loop control is sometimes used to compensate for instabilities caused by backlash. Backlash arises in systems where a motor is coupled to a load through gears or lead screws.
