Servo motor

[keithski122]

When I was using my machine today I took notice of how it was working.I think the servo motor adds controllability.With the clutch motor it previously had I would press the pedal and not know if I would do one stitch or 15, with the servo I can tap the pedal and do one stitch, keep tapping and I can do lots of one stitches.Generally I guess I sew about two or three inches at a time on a straight line or I can tap it one stitch at a time around sharp curves or up to a corner.With the clutch motor I would have to do stuff like this very carefully or by handwheeling the machine.With the control I now have with just the servo and needle positioner I have no need to go any slower.

Sounds like great controlibility, what motor setup do you have

       I have a 111w152 fitted with a servo and  45 mm pulley and a needle positioner.   I like that 1 tap of pedal will take needle down thru 1 full stitch just till it is starting on way up no missed stitches. With no reverse on this machine

I can start out facing backwards tap 3 taps and no I will have 3 complete stitches then turn my work around and run it at a very comfortable speed with the servo motor speed set at 500 rpm top speed.Then when I reach end of my stitching 1 tap with heel on front of the pedal and the needle goes to the top and I can release presser foot and pull work out no manual hand wheeling at all. When I first installed it I had it stopping at very bottom and would skip stitches and I would have to work the hand wheel to get the thread to release from the rotating hook assembly.I can punch thru about 3/8" of leather with no problem 1 stitch at a time.

Mine is a juki 563 with a jack servo motor and needle positioner.I have extended the arm on the pedal by about 2 or 3 inches and the same on the motor controller.I found that without the extensions I had too little ankle movement before stitching would occur and I would accidently stitch

I've got a needle positioner on my Consew/Efka servo machine. I love it and wouldn't want to sew without it now. I managed to find a manual for the positioner and it is very easy to set up so that it stops exactly where you want it to.

can i use a 45mm pulley from my clutch motor to servo motor? are they compatible?

I going to assume you mean that you are planning on removing the 45mm pulley that is on the clutch motor and installing it on the servo motor. If the diameter of the hole in 45mm pulley is the correct size for the shaft of the servo motor, yes it would probably be a good match. If the hole in the pulley is to small you will need to ream it out, if too large you would need to sleeve the hole down or just buy a 45mm pulley that correctly matches the servo motor shaft.

and it depends on the pulley - some clutch motors have pulleys with a tapered bore and to my best knowledge they do not fit on any servo.

Some clutch motors have a 3/4 inch shaft (~20mm). Most servo motors have something close to 13 or 14mm, which is way under the pulley bore on the clutch motor. You would need a custom bored sleeve to take up the slack.

Hello, I am from Oregon and a long-time sewer, mostly of clothing and now leather bags. A few weeks ago I purchased a Consew with a Premier 550W Servo motor. I found it way too fast and changed out the pulley to a 45mm one through Amazon, and got a shorter belt to fit. Yesterday I finally got all set up and noticed that the handwheel on the machine is Very hard to turn and there is a squeak/ squeal coming from the motor when I manually turn the wheel. (this was not present before) I thought it might be the belt or my assembly of the pulley, so I took off the belt and the handwheel turns fine, but the squeak remains even if I take off the nut holding on the pulley and partially remove it. It seems to be coming from the motor, as if it has a brake on.  There is no noise or hesitation when sewing (although I stopped until This is resolved.) I called the dealer and they plan to call back tomorrow.

Any ideas?
