Take your sewing to the next level with this motor and speed reduction upgrade for your Ultrafeed® Sewing Machine. If you already own the Ultrafeed® Compact Sewing Table or the Ultrafeed® Industrial Table and you're looking for slow speed control while you sew, this is the motor upgrade package you need. The Workhorse® Servo Motor and Speed Reducer give you the ultimate in slow, stitch-by-stitch power for the most precise and controlled sewing.

The Sailrite® exclusive Workhorse Servo Motor is a 550 watt, 3/4 horsepower servo motor designed for continuous use. This quiet, energy-saving motor features a 12 coil design, which creates smooth motor rotation and a fluid motor-to-machine power transfer. The Speed Reduction Pulley slows the motor down even more so you have incredible power and control when sewing at extremely slow speeds.

We highly recommend this package for Ultrafeed owners who have the Compact Sewing Table (#122865) or Industrial Sewing Table (#120934) and are looking for incredible precision and the ability to sew one stitch at a time while maintaining total control while sewing. If you are a leatherworker, the Workhorse Servo Motor and Speed Reducer is an exceptional sewing setup that will turn your Ultrafeed machine into a top-notch leather hobbyist sewing machine.

The Sailrite Workhorse Servo Motor comes with a two-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.
