  • Repurposing 3/4 HP Clutch Motor From Ind Sewing Machine

    Old school sewing machine motors are becoming obsolete in the minds of some
    and surplus inventory is being sold off.

    An example is this 3/4 HP E-Z Clutch Motor. 110/220V 1Ph. 3,400 RPM max.
    19mm keyed shaft. Comes with switch, cord, pulley, isolator mounts and linkage.



    These are typically slung with the mount above and the J-arm below. The
    J-arm is the actuator for the mechanical clutch, which does dual-duty as
    a brake.

    I have a couple of uses for these in mind.

    Please share your thoughts. With a speed of 3,400 RPM max, I would love to know what are you planning.

      I've bought a couple like it & put them on small lathes. http://www.ebay.com/itm/350384973419...84.m1423.l2649
      Can't beat $91/Delivered for a variable speed reversable lathe motor with a brake!

          Yeah, pull the lever and the clutch slowly engages. I would not expect a good lifetime running under a lathe load on the clutch style motor.

            The ones I bought have no clutch,sorry. They look almost the same.

              i agree. iv'e reconditioned my clutches in both my industrial sewing machines as they get pretty much glazed / worn out from easy starts. rarely do i sew wide open speed, i can;t hardly keep up with the feed of material.

                I also have a motor just like that. It came off from my industrial sewing machine when I switched over to a servo drive. Still not sure if I like the servo motor as well as the original one. The servo motor is supposed to run at various speeds with full power, of so I have read, but it doesn't. I may put the old one back on.

                Davidh,
                I hear you on the speed of the original motor. Something about a needle going 3500 strokes per minute makes it hard to handle. The lady I bought the machine from told me it "scared her half to death".
