|DanTwoLakes||I, personally, don't feel the need to modify my servos in any way. I'm perfectly happy with how they run.|

Thanks for your input Dan TwoLakes. I saw several reviews of the Reliable on Amazon.con always good to combine different inputs from users. I also found an interesting link on howto modify speed control on a servo (compatible brands/types listed there). Do you have experiance with this mod? I think to use this for tiny decals on vamps (instead of using 29K, want to learn on the 145). Has a link back to hotRod forum:

|DanTwoLakes||Sewing machine motors all have the same footprint of three bolts, which means they are interchangeable on any sewing machine table. The only thing you may have to do is change the belt to fit the motor. I have had great luck with the Reliable servo motors. Their latest machine is the Sew-Quiet 5000, which should be available in Europe. It costs more, but it is more than worth it. I have Reliable motors on three of my sewing machines, and have never had any trouble of any kind.|

|IrisA||Auw, 😣. I use my 29K for belts or vamps in shoes, the head turns 360Dgr. Which servo would fit best for a 145? This clutch has max 1450rpm so it is not fast.|
|07-16-2016 07:41 PM|
Auww! Which servo would you recommend? (Hng I cannot type well on a mobile phone)
I have no finger guard but Im used to sew with just 1 hand on a 29k Singer

|bentwings||The servo motor will go slower than a snail if you want it to. I ordered the servo the day after I sewed my finger.|

Thx for yr advise Bentwings! Which servo would you advice for a 145 that is available in Europe (big diffrnc us eu!)
As for now I want learn on the clutch (I just got it for 7 days my hubby sais) so I moved the treadle and put the 0 at highest to fit my short legs (so the moment will be on the legs not the body). I get 4 to 5 stc a sec at slow rate, 1 or 2 at a single "trap", can a servo too?

|bentwings||The easiest way is to just convert to the servo motor. I did and it has made a world of difference. I sew all kinds of things just for fun. I train dogs so making dog leashes and harnesses was one of the first things I did. I now make pocket tee shirt to hold dog treats. These are tough as the material is light and stretchy. Without a servo these would be impossible.|

Slipping is ok then

Ehm Hello, is this thread still living?
I just bought a pfaff 145 h3 wirh original clutch. Sews very nice, cleaned all etc.
Clutch question: is it normal to slip sometimes? Not bad for motor? I'm learning slow and fast wit treadle, corners by hand.
I'm used to singer 29k1 29k56 by hand(!) so this motor is nice fast
Thx Iris (from holland)

Those belts are generally considered a stop gap until you can replace it with an actual one piece belt, but you are right, they are tougher than tough.
You will never have to replace a belt on a sewing machine once you get one the right length. You never will have a situation where you're sewing at a constant speed for any length of time. I use 3VX cog belts on all 3 of my sewing machines.

speaking of V-belts, have any of you ever used the segmented type v-belt?
They run very smooth and have a long lifespan as compared to a standard v-belt.
I was a millwright in a very large industrial setting, 67 acres under the roof and we had a lot of machines running of v-belts. I changed out lord know how many v-belts over the 30 years of my employment there. (all as a millwright)
I never once replaced a broken segment belt. I do not recall replacing any of them as a scheduled maintenance it either. the darn things lasted a looooong time.
The belts we used were a steel rivet and leather (brammer)design.
the belts in the link I am posting are a segmented belt but not of the exact design I have experience with. I am posting the link to show the concept of the segmented belt.
when I acquire my sewing machine I will be adding a servo motor if it doesn't have one and will be putting on a segmented belt.
fyi, cheesy as they look, dont think that a segmented belt is not for hi hp/torque applications. many of the ones I installed and removed were powered by 100hp electric motors spinning 5000# flywheels. 6 belts were used in that application.

|DanTwoLakes||It is not top of the line, but would probably still be better than the clutch motor you have now. Check out the specs on this one: SEW QUIET 4000 As far as I'm concerned, this is the best one out there. Yes, it's $65 more, but the shipping is free and it is well worth it.|

I just ran across this servo motor. Is this any good or just cheap junk.???
I'm going to call them Monday and see if the price still holds and more info.
