Not exactly creep but the ramp up speed is so slow it almost feels like it. The creep you mention is what I would call slip. With my motor and synchronizer, it's set up where I can get one stitch per tap on the treadle. I think buried down in the settings, I can adjust the speed as well. I don't want others to think I'm promoting one brand of motor, but if you search in my previous posts and then do a little research, you can find out more details from others to see the motor in action. After that, then you can make your own decision.

1) change the motor pulley to the smallest you can find, usually 45mm 2) go with a larger pulley substituted for the handwheel 3) speed reducer 4) I tried 1 and 3 above, ended up getting a different servo motor that would start at 50 rpmand not 200 or 300, game changer -

Pardon if my terminology is incorrect but I would like to change from a knee operated presser foot lift to a foot operated lift on my Pfaff 545. I find the knee lift to be hard to operate without having to readjust my body position to gain a little more leverage to push on it. I have no problems with the force of the foot on the material and I don't think I can reduce the presser foot spring force any more - it has a double horizontal spring across the top which is at its lowest setting. I would like to have the lift separate from my main treadle pedal so adding a second pedal or button would both be an option. Just wondering if anyone else has done this -

I can understand the desire to make something, good luck with it. Keep us informed, might be something others would like to have.

Get yourself a Kinedyne needle synchronizer for accuracy but I'm pretty sure the servo motor controller is what really controls the functions, the synchronizer is just a switch to indicate where the timing of the machine is. The Kinedyne is an optical synchronizer and is super accurate. http://kinedyne-motor.com/products/HM-750SH/234.html You could just get the Kinedyne motor and synchronizer and be done with it. Just sayin - Talk to Ryna at http://www.neelsaddlery.com/ I have no affiliation with Kinedyne or Neels Saddlery, just a very satisifed customer.

Wizcraft is correct, my needles are the 134-35 as well. My machine model is 545-H3-6/01 CLPMN. Mine is for leather so that might explain why I have two leaf springs on mine as opposed to your single spring. Other than that, I think we have very similar machines.

I have a similar machine with a serial number that is also stamped like yours, I can't seem to be able to date mine either. I also have the same spring across the top but I have two, it really clamps down on the material. I don't recall what my model number is, I can take a look at it later today. I have the same brand of needles and will see what size they are as well. It's a great machine and will sew through anything, good luck with it.

If they all have the same connector, then I would say they are probably interchangeable. However, this is also similar to saying are all digital servo motors the same. While the positioner is really nothing more than a switch to mark where the needle is in the up and down position, there is the issue of quality - much like servo motors. I recently purchased a Kinedyne motor and positioner, the positioner when compare to a less expensive model actually feels better. When opened up to dial it in for my machine, it's obvious the quality is much better. I should also say that there are separate dials that are adjusted for the needle positions and an optical sensor for those wheels, whereas with the cheaper model, you rotate the hub that connects to the handwheel to dial in the needle positions. Just my experience with a couple of them .....

I have bought two edge guide presser feet for my Pfaff from CKPSMS through Amazon and am very satisfied. It can be hard to find parts that fit the older Pfaffs, these were just fine. Bobbins in my opinion can be bought anywhere and they should be good.

I've found so many web sites with claims of something being the best thing since sliced bread but then when you try it, you end up realizing it's not what was claimed. The Kinedyne motors have videos but they're not that easy to find. I've read so many articles for people looking for the "Holy Grail" of motors, just wanted to let folks know I think there finally is one - and glad you agree!

A little pricey yes but this is the 4th motor I've bought chasing what I was looking for in a servo motor. I'm thinking I've found it. Now, if I add up all the money I've spent on the previous motors, I could have bought two of the Kinedynes and been satisfied all this time. Sometimes you just have to weigh what's important to you, a few dollars for less frustration works for me - besides I had sold some other stuff from another hobby that helped fund this.

From what I was told by Ryan (if I remember correctly) the 750 SL is let's say the base model that runs as slow as 50 rpm and is rated at 1 hp. The 750SH is the same but is built to run on the slow side longer if that makes sense and is also rated at 1 hp. The slower they run the more heat is generated so I believe it has to do probably additional heat sinks in the controller. The 1000SH is the best one, it too can run all day at very slow speeds and is rated at 1.3 hp. Just last week I had tried one of the generic "750" watt motors with needle positioner from Amazon. I think it was on and off my machine in two days, it would have been sooner but I still have a day job. The Kinedyne is so much more refined, is much heavier is very well built and the positioner is super accurate. The generic one would drift all over the place, the Kinedyne is spot on every time. I really like the controller being separate so ou can easily change settings without having to crawl under the table. They are not cheap, but honestly you get what you pay for. A generic digital servo runs about $75-100, a good analog servo is now about $175. The Kinedyne starts at just under twice the analog model. I would rather not quote Neel's Saddlery's pricing and suggest you contact him yourself. And don't worry about dealing with a smaller company, he is a top notch guy. I did wrestle with the cost, however after getting it I really don't regret it. You might watch the videos from The Thoughtful Woodworker, they helped me make up my mind.

Just got my Kinedyne servo motor last night from Neel's Saddlery. Ryan is a great guy to deal with but the servo motor is unbelievable. Granted I'm new to sewing but the power and especially the slow speed of this thing is fantastic. To me, this is similar to comparing a manual transmission to an automatic. Don't get me wrong, I love manuals but not having to deal with finding the friciton point of a clutch motor or dealing with the instant ramp up of a cheaper servo motor is priceless, you get a true one stitch at a time. I built a speed reducer and it worked but not like this motor. It's smooth as silk, powerful, quiet and everything I've been trying to get out of a motor. The HM750SL, HM750SH or even the HM1000SH is what you want to look at they all have the 50 rpm lower limit. I know some have kind of written these motors off but everything they say about them is true. I highly recommend the Kinedyne motor - and I do not get anything for saying this -

One other possibility is to install a smaller pulley on the motor, 45mm is typical. One problem though is the motor shaft on that motor might have a tapered shaft. Tapered pulleys for that are difficult if not impossible to find. The next choice was already mentioned, that being a speed reducer. One other option is going to a larger pulley on the sewing machine. A friend of mine did just that and really liked the reduction in speed. He used just an off the shelf 1/2" bore, 6" pulley that you can find at a good hardware store or order on-line - as long as your machine handwheel shaft is 1/2" that is.
