Members Yetibelle Posted February 16, 2017 Members Report Posted February 16, 2017 Really - get the Servo motor - Clutch motors also use HUGE amounts of electricity to stay spinning, the Servo motor is nice and silent and uses a lot less electricity. You will not regret it. Quote One day I hope to learn how to sew..... Singer 111W155 - Singer 29-4 - Singer 78-1 - Singer 7-31 - Singer 109w100 - Singer 46W-SV-16 - Adler 20-19 - Cowboy CB-4500

You will not regret it. Actually, an AC motor that has no load on it uses very little electricity to remain spinning. That said; the buzzing noise, table vibrations, jackrabbit starts, massive power dump into the machine at the onset of a stitch - are more than reason enough to remove the bloody thing and put a servo on it. I was fighting my clutch motor again last night trying to resolve a tension spring issue (top tension bracket wasn't fitting quite right causing the thread to stick behind it) and was seriously questioning my Singer 211G purchase vs a 441 clone and wondering how I was going to come up with the money to upgrade if the servo didn't do the trick. Well, my servo's been on for a couple hours and I'm already completing work that looks better than the last guy I paid. Get the servo! Quote

Unless you have some nostalgic attachment to plain clutch motors, there's really no need to subject yourself to them. Even a $115 cheapo servo motor with a small 2" pulley will make a world of difference. For around $200 you can buy one of my personal favorites, a Sewpro 1,100W servo motor with plenty of low-end torque and very low 100rpm starting speed (most other servo motors start spinning with 300 rpm.) Can you share a link to this Sewpro 1100 servo motor? Google search is not finding it. I don't see it on the SewproUSA site either. Thanks. Quote
Uwe Posted February 17, 2017 Report Posted February 17, 2017 Sewpro does not have the SP-1100 motor (or SP-1100 NPFL with needle position and foot list) on their website yet, I'm not sure why. They had brought the motor to the TexProcess trade show in Atlanta last May, which is where I first met Sergey (Mr. SewProUSA) and we talked about the motor at length. Excellence in sewing technology and webmastering don't always go hand-in-hand. You basically have to call and inquire about the motor, something rather common in the sewing machine world. One key feature I like about this motor system, aside from the power and low speed torque, is actually the control interface. You can control the needle position function with a simple button that cycles through Up/Down/Off states, which is how it should be. Motor top speed is adjusted via simple "+" or "-" buttons, which is also how it should be. Other, more esoteric functions are set via a crude menu system that is just as cryptic as other controllers. The needle position sensor is optional and runs about $25, I think. I'm not connected to SewPro in any way other than having talked to Sergey and ordered two of his SP-1100 motors. I just like the motor, that's all. I took a few pictures of my SP-1100 NPFL motor, which is currently serving mobile test setup duty. The motor body itself measures about 4" square on the mounting faceplate and 6" long (not counting the pulley). Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
Members ndnchf Posted February 18, 2017 Members Report Posted February 18, 2017 Thanks for the photos and explanation Uwe. No wonder I couldn't find it. I've got a Singer 31-15 clutch motor machine I've been thinking about upgrading. I like the low speed torque feature, I'm not in any hurry with my projects. Steve Quote
TZHunter Posted February 18, 2017 Report Posted February 18, 2017 Steve, I've got a 31-15 that I too was seriously thinking about getting one of these servo motors for. Let me know how it works out for you. Quote
Members KeithHideWorks Posted February 18, 2017 Members Report Posted February 18, 2017 Must have that motor..............Any idea when they will be available for sale? Quote

Could be.
