Badem Report post Posted January 5, 2019 I'm in need of a 'slow' sewingmachine for precision and control stitching and found a good deal now. The advertiser send me this photo of the motor; it's a clutch motor, he called it a 'leather motor' since it goes at about 1425 r.p.m. I have no experience with motors/electronics and could use some advice regarding this offer, or deciding to upgrade to a servo. I made the agreement that I can either buy the machine without the motor (and order a servo elsewhere) or buy it with, but it will have an impact on my budget. Will this motor be slow enough for my needs? I would like it to go stitch by stitch at times, I'm not at all interested in 'fast' options. Also I prefer the machine to be quiet, which I know a clutch is not. What is the aprox. value of this clutch motor (without machine)? Thanks ! Quote Share this post Link to post Share on other sites
Constabulary Report post Posted January 5, 2019 Buy a servo motor + maybe later a speed reducer or DIY one! You will not regret it. Value of a used clutch motor? Almost nothing because no one really wants them - maybe 25 - 30€ if you find a buyer. College sewing is blowing out their NOS clutch motors for 28GBP with wires and switch.

Badem Report post Posted January 5, 2019 Thanks @constabulary for putting things in perspective. I wanted to know the value so I can negotiate the purchase without motor Quote Share this post Link to post Share on other sites
DFH Report post Posted January 5, 2019 Go with the servo motor you will never regret it . And adding the speed reducer makes things even better !!!!!!!! Quote Share this post Link to post Share on other sites
Northmount Report post Posted January 5, 2019 To go stitch by stitch, you need a servo motor with a speed reducer. If you are well practiced, you might be able to do it with a clutch motor, but would have a number of misses. Tom Quote Share this post Link to post Share on other sites
dikman Report post Posted January 5, 2019 (edited) No question whatsoever - servo motor and fit a small 2" pulley to it. You'll probably find that you'll need to fit a speed reducer too as has been mentioned. I recently had to get rid of two clutch motors I didn't need and almost had to give them away, I got Au$10 each and figure I was lucky getting that!

Wizcrafts Report post Posted January 5, 2019 Badem; This is the servo motor I and a lot of our members are currently using. The knob is a potentiometer, but used to be a multi-position switch. It is equipped with a 50mm pulley. I can sew at about 1.5 stitches per second direct from the motor. On another machine I installed a 3:1 speed reducer. I can sew a stitch every other second. It has brushes that are replaceable and has a cork brake that can be ground down or removed, as you prefer. See if you can find one like this in your Country.

I would ship from the US, but customs tarrif is quite high here, in germany... Cheers Alex Quote Share this post Link to post Share on other sites
Constabulary Report post Posted January 6, 2019 importing a 110V motor from the US to Europe makes no sense at all. I haven´t yet seen this model on the continent but a similar motor is / was the HMC ZYT116. I had one but it made a permanent high frequency beeeeeep sound and that was so unbelievable annoying. I ended with a 750Watts Jack Servo from College Sewing. I meanwhile have 2 and a 3rd (and maybe 4th) one will follow soon. Quote Share this post Link to post Share on other sites
Badem Report post Posted January 6, 2019 wow thanks all, makes it very clear ! The machine is an Adler 167 with walking foot; any tips on watts/torques/whatsoever I should take in account when choosing a servo? 550watts, 750watts? I don't work with leather but with tarpaulin. Can I later on upgrade with the speed reducer or should I get it right away? Maybe I don't need literally stitch by stitch until now have been working as well partially manually when I needed the real precise work, that worked fine, but overall I prefer super control over a motor doing "vroom" and eating the project, so to speak..

dikman Report post Posted January 6, 2019 A 550w motor should be plenty, but it's always a good idea to go with the biggest you can afford. Try it without a reducer first, it may be fine for your needs, if not add/make a reducer (don't forget to fit the smallest pulley you can to the motor, every little bit helps).
