With 2 M3*4 and 2 M3*25 screws you can add close loop control to your nema motor. This model is made to respect the profile of the motor and add only 6mm behind it.
Simply add a magnet to the shaft and screw this. That's it. There is space to get the wires out.
You'll need to solder the wires on the surface of the PCB, not through.
This model use only 4 screws to save you some material so keep 2 of the original motor screws in place.
The author marked this model as their own original creation.
