REX INDUSTRIAL SEWING MACHINE SERVO MOTOR 550 WATTS

Smooth, quiet, controllable motor for my walking foot. If you still don't like the speed, simply install a smaller pulley as I did. I used a 1-3/4" pulley for further speed reduction and torque. The length of your belt has a lot to do with how the speed control functions. I started with a belt that was too short, and the motor had to be lifted to its highest position. Then the treadle rods weren't long enough to reach the correct hole in the motor control arm (I like to use the hole furthest from the motor for best control). With the 3" (75mm) pulley, and short belt even the servo seemed twitchy and very similar to my old clutch motor.So I replaced the pulley with the 1-3/4" version which made the 39" belt the correct length. With the motor height in the middle of its adjustable range, the treadle rods now reached the correct hole in the motor arm. This combination made my Consew 226 walking foot very easy to control at slow to medium speeds. I can punch through several layers of 4oz. leather stitch-by-stitch without issues.If you lengthen your treadle rods even more, the pedal will bottom out before reaching the top speed. This gives you even more control, especially for beginners. At the lowest speed setting, this machine will not even move. Not to worry, just dial the speed knob up a bit to accommodate your machine, and the thread you are using. I set my speed dial to 1/3 or 1/2 of max (around 1280 RPM). The speed is very easy to adjust and the foot pedal is variable speed too, so the machine will not operate at maximum set RPM unless you mash your foot down.

As others have noted, there are no installation instructions but it is just a motor on a mount that you bolt onto a table...Unfortunately, my table and machine were old enough that I could not use the same bolt holes as some lucky buyers here have been able to do. That said, it was not hard to mount the motor using the supplies bolts and gear. A quick removal of the spring clip lets you take the mount off the motor, which then makes it easier to put the mount against the table underside and mark for the drill. The carriage bolts are then pushed down through the top of the table, either drill a small recess to let them sit flush or do as I did and hammer them in so they grip the table better. Then get the mount all bolted on and hang the motor.If you are like me and had to drill your own bolt holes, you may have to get a new drive belt too. My old unit was using a leather cord (yes, that old), so I used a piece of cord marked at the length I needed and went to the auto parts store where I looked through their v-belts until I found a short one that looked right. Since the motor is adjustable for tension/height, I was able to get enough adjustment to snug up the belt.Having a v-belt drive makes my machine noticeably better, as the leather cord could slip and I couldn't get good piercing power on thick items unless I ran the machine full tilt (which was near impossible to get a straight line with).The motor tolerates being dialed down in speed pretty well. Yes, there is a let off at the lower region, but I have no big trouble getting a nice easy and controllable pace using my foot plate.I recommend this to anyone who wants the control and flexibility of a servo motor. I am VERY glad I bought it.

It arrived in fine shape, shipper let it sit in water and bottom of box was soaked, but motor in styrofoam and wrapped in a plastic bag was fine. I had to use the insulators from the old clutch motor and bolts to install it. Else I would have to put holes in the table with the hardware it shipped with. I also was able to move my smaller pulley from the old motor to this one. I need a longer set screw, but was able to make one from an extra bolt I had. After installed it worked fine, and it was a bonus to have the outlet on it for my light. Now that it is so quite vs. the clutch motor it helps to have the light plugged in so you remember to turn the motor power off. Hardest part was holding that 25# old motor up while removing the bolts to take it off.

Had this motor a week now with just a little light sewing.The good:Fit right into the same bolt pattern as the old clutch motor that came with my Juki 451.Seems well made, especially for the price.No noise unless running the sewing machine. E.g. no noise when motor is turned on, but only if sewing machine treadle is pressed.Speed 'mostly' adjustable.The bad:On mine, there is no motor movement between 0 and just under 660rpm. At 660 it works but is hit and miss. At higher speeds it does fine.You can feather the treadle to go slower but it's difficult. So you can't slowly punch through leather at 60-600 stitches per minute or 1-10 per second.

Very easy to install. We have a Rex 26-188. The motor fit the same holes, had the same length bolts, etc. Went together completely with no adjustments. Don't expect directions - it does not come with any and rightfully so since every machine is different but there is a u-tube on line installing a 440w that is nearly identical so it can walk you through the replacement. The motor is complete and came with additional brake cork, bushes and fuse for the on/off switch.We did contact the manufacturer through Amazon about the extra brake cork just to make sure and they replied within an hour. That was super responsive!!! [There is some incorrect info on Amazon questions and answers - it does in fact come with the treadle connection and does not come with a belt from machine to motor. You use your existing belt.]The motor is much more quiet and we are able to slow it down to a smooth slow start for corner and leather work. Very pleased with purchase.

This product is great! Installed it on a Juki DL555 with little modification(needed a shorter belt) and now it is like a totally different machine. Far more control than with the clutch motor it came with and powerful enough even at slow speeds.. This product arrived earlier than the predicted date and was exactly as advertised. I would recommend this product and this seller to anyone looking to replace the motor on their industrial sewing machine.

All good works as expected a 45 mm drive pulley instead of a 75 mm or your choice when you purchase would be ok.

Works well, could use a smaller pulley to slow it down more. Good power

I installed this motor on my singer 211G166 industrial sewing machine. It had a clutch motor which was hard to run at a constant slow speed. The servo motor allowed for this. Plus the motor only comes on when you need to sew. The clutch motor runs all the time also has friction wearing parts. This is not the case for a servo motor.
