1852 Available


A Sailrite® exclusive, the Workhorse® Servo Motor is a 550 watt, 3/4 horsepower servo motor designed for continuous use on industrial sewing machines. This quiet, energy-saving motor features a 12 coil design, which creates smooth motor rotation and a fluid motor-to-machine power transfer. A brushless motor, the Workhorse provides high torque even from a complete stop! This servo motor also offers fully adjustable speed settings, which let you set your top stitching speed while maintaining variable speed control. Variable maximum speed settings range from 400-3600 stitches per minute.

The Workhorse Servo Motor comes standard on all Sailrite® Fabricator®, Leatherwork and Stitch Master Sewing Machines. It can be used on other industrial sewing machines to replace clutch or other servo motors. The motor comes with both a 21-tooth cogged motor pulley, for use with a cogged belt and our Stitch PRO Balance Wheel, and a 3L V-Belt compatible motor pulley so the motor can easily be adapted to your sewing machine.

Please Note: The two belts required to operate the pulleys are sold separately (#120580 and #100815).

The Sailrite Workhorse Servo Motor comes with a 2-year limited warranty. This guarantee covers defects in material and workmanship. Damage due to improper use, neglect, impact and normal wear are not covered under this warranty. Furthermore, this warranty is voided by disassembly, repair or alteration by the owner or unauthorized third parties. This warranty is limited to the original purchase price.

The Workhorse Servo Motor is not designed for use with heavyweight balance wheels like the Monster® II Balance Wheel. Use of a balance wheel like this could damage the motor and will void the warranty.

Old machine had uncontrollable clutch motor. There is no comparison. This sailrite servo motor is way to go. Just wish it had a switch that I didn’t have to reach under and to back of table

Just what the doctor ordered!

Replaced crappy clutch motor. Love case design, light weight, power. Might add a speed reducer later for ultimate control but so much better than original. (Had to change pulleys, make linkage design changes on original, but was still a hold your breath kind of deal. No longer, very reassuring. Installation was super easy, once I got the old boat anchor off. Shortened one bolt, but didn't really have to. Easily pushes through thickest thing I will ever stitch, on slowest speed. Machine is Juke NU-1541S. For those that are really concerned, I can bump forward/reverse about 1/3 to 1/2 stitch. Smaller movements require manual turn. Like the feeling of the 12 motor coils when manually moving. Very, very quiet. For me personally, did not see a need for the pulley cover.

Replaced a clutch motor with a Workhorse Servo Motor on a Juki LU-563.

I received my workhorse motor, and have to admit that I was a bit skeptical just feeling the weight of the box. I was replacing a 40-50 lb. clutch motor, but the details said .50 hp on the specs, and my clutch motor was .42 hp, so away I went. The installation was a snap. It took more time to undo the staples holding the old wiring in than it did to install the new motor. Working with it is a dream compared to the old clutch motor, and I fully enjoy the extra control that I now have. The one thing I didn't expect was when I tilted the sewing machine head on my old Juki LU-563 to install the belt, the entire table moved, which had never happened to me before. The small weight of the new motor simply made everything lighter. Not complaining, believe me. I love this new motor!

Works for my 1960's Consew 101

Replaced the old clutch motor on my 1960's Consew 101. The original motor was a 1/3 HP and this is a 3/4 HP, but it seems to run pretty comfortably around the '24' setting on the motor for me. I did have to adjust the hook timing and tension after the swap, but as this was the first time I had done such a task, I can't say if that was directly related to the motor swap or other factors.

Get your work done better with the Workhorse

For anyone still sewing with a cork clutch motor, a switch to SailRites Workhorse servo motor will be a huge improvement to your sewing experience. Quiet, very strong, only runs while actually sewing, full pressing power at extremely slow speeds. Highly recommended.

This is a game changer for me. I sew infrequently I've never been able to reliably control a clutch motor. Easy to install and awesome to use.

I am super happy for going with the WorkHorse motor as it works just as the advertising says. Perfect for working with leather, I can use it in super slow speed and or very fast speed without missing a stich, Sailrite products are the way to go!!!

Powerhouse of a servo

This servo is dope! I paired it with a consew 206rb (industrial walking foot machine), and it’s a match made in sewing heaven. The workhorse has a lot of low speed power, plenty enough to drive through many layers of sailcloth, canvas, and webbing at a crawling speed. It’s quite, light and small. When you need the speed it’s there as well. Very happy with it
