Yes, what's a real test? No high speed production here, just lots of slow detail work.

Well let us know how she works once you hook up that mean motor to that lean machine!

Just teasing a bit here, generally speaking, a Pfaff 438 is used or can be used for sewing up to 6,000 RPM, depending machine subclass and depending on goods being sewn.  Ultra high speed capable zig zag.

However, many are using this for light to light medium dacron with light to medium weight threads. 

Still, this is not pushing the motor like a walking foot may, in terms of low end torque.

Thanks for clearing that up Greg. Better to get a little more motor than you need rather than the other way, as long as it is not dangerously powerful. Sounds like Hockeymender just needs a little a little advice here.

...ISM SV-71 motor. I just received one and am contemplating putting it into service but wanted to get some input from anyone that uses (or has used) this motor. Looking thru the manual the setup seems a bit convoluted, but that may just be my take on it. Welcome any feedback/reviews. 

 

Hockeymender,

Found the manual I think, is this it?

I have to admit, I find some of my manuals are hard to understand, especially my SWF embroidery machines, made in Korea. Much of the "English" version of the instructions are very broken, difficult to understand, or incorrect because of poor translation. Drives me crazy

That's the one.

Oh boy, no pictures or diagrams to help explain. Joe, have you ever installed a sewing machine motor before? I've installed a few, but not a servo yet. Hopefully someone can chime in who has installed motors like yours. Can you describe what part of install has you the most puzzled?

Installed many motors in the past. Most servo motors with a schronizer attached. Those need to be programmed and really are not a big deal. When the schronizer arrives for this motor I will install this arrangement. The programming looks a little less straight forward than some others, but I'm certain I'll figure it out. 

I just wanted to know if anyone has one of these motors and if so, how well they liked or disliked them.

Forgot, guess I did install a servo a while back, way back! I had forgotten about it because it died on me fairly quickly so I haven't been to keen on servo type motors since. The machine I had it on I no longer own, my first walking foot machine. But that was when servo motors first came out and it sounds like they are being made better now, so I'm ready to try another.

My main machine that I use these days is an older Pfaff 545 with large bobbin, made about 1979. A fantastic machine in like new condition, it's a monster! I like the motor that is on it, but it's an old clutch type and goes like the wind. I'd like to put a servo on it to slow it down when sewing finer detail stuff. What I sew with that old Pfaff is mostly thick canvas/tarp, banner material, and sunbrella. With a servo motor, I would use it for leather clothing items and handbags.
