Digital rotary incremental encoder for educational purposes

Ordinary electric motors provide machines with the necessary power and torque, but as such, they cannot determine their current position or how much they have rotated. One of the devices that made CNC machines and robots work in the first place is a digital encoder. The digital encoder gives feedback to the electric motor controller about its position and how much movement it has made. To control machines this way, it is necessary to describe a motor with a universal language, which is the G code, where to move, how fast to move, and what path to follow. Therefore, by programming the G code and uploading it to a CNC machine, it is possible to move each axis of the machine for the programmed value. In order to understand how the digital incremental rotary encoder works and its operating logic, the electrical parts of the device are explained. Also, for educational purposes, an experimental model has been made and described. Affordable components were used in the production of the encoder which enables everyone who wants to learn to produce one.
