Rowdy7720 Report post Posted March 26, 2020 Looking for some suggestions on a servo motor upgrade for a Singer 16-141 I have aquired... the Machine is in perfect working order and sews very nicely, just way too fast for the leather projects I do. So, my questions are, which servo motor do you all suggest and why? I also have heard I may need a speed reducer as well, is this true? Thank you in advance for the help!

Wizcrafts Report post Posted March 26, 2020 I and many others here are currently using the Family Sew FS-550s servo motor, with a 2" pulley, shown here. It has a front mounted dial to limit the top speed. The slowest speeds are a little lacking on torque, so the slow speed punching power will depend on the diameter of the pulley on the hand-wheel on the machine. If the machine pulley is 4" diameter, you will get double the torque and be able to sew about 1 to 2 stitches per second before it stalls out. Adding a speed reducer will double or triple the speed reduction/torque multiplication. It also makes it harder to hand wheel the machine without powering up the motor. Speed reducers are listed further down the above linked page. Any change in the motor or its pulley will require a different length v-belt. Quote Share this post Link to post Share on other sites
