Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For industrial applications, incremental encoders (used when only relative position is ...

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 ...
