Aftermarket sewing machine servomotors minimum speed is generally about 200 rpm. This low idle speed is still too high for many users.
This vid shows the way we walked trying to reach the best stitching speed control out of a standard servomotor (here on a Pfaff 335).

Please note that :
#1 Needle Positioning Systems are NOT COMPATIBLE with the use of a speed reducer.

We manufactured the small pulley and the speed reducer of this video.
Feel free to contact, comment or ask :-)
