A motor encoder is a rotary encoder mounted to an electric motor that provides closed loop feedback signals by tracking the speed and/or position of a motor shaft. There are a wide variety of motor encoder configurations available such as incremental or absolute, optical or magnetic, shafted or hub/hollow shaft, among others. The type of motor encoder used is dependent upon a number of factors, particularly motor type, the application requiring closed-loop feedback, and the mounting configuration required.
“For a long time I wanted to make a device that allowed non-digital people to enter physical measurements for digital production. While using some cheap quadrature encoders for a servo control system I realized that these encoders are useful for …
