Anyone care to comment (pro or con) on this unit:



Consew cs1000 servo motor

I was looking at the Sewquiet 5000, but thie above unit is going for $120 on ebay.

I'm hoping to get something that starts slower than a clutch motor, and can then be smoothly sped up to working speed.

I can handle "fast" well enough, but sometimes when the thing lurches into motion I end up crooked, and mess up the whole seam because of the slam-start.

It's specs are almost identical to the SewQuiet 5000. I have had no problems with any of the 3 SewQuiet motors I own. I don't know anything about the Con Serv CS-1000.

How slow does the Sewquiet 5000 go to?

I've read messages about people putting 50mm pulleys on them, but it seems like you could just turn the speed down some to make up for the pulley size... Or am I missing something?

The Consew unit goes down to 100RPM, but I know nothing about the reliability of the brand or it's performance, while several people here have raved about the SewQuiet motors.

I'm trying to find smooth starts, but the ability to speed up to a efficient working stitch rate once underway.

You can slow the 5000 down to literally one stitch at a time if you need to, and adjust it up to its max speed. The motor comes with a stock 90MM diameter pulley, but buying the 50MM pulley seems to be a little silly to me. The SewQuiet 3000 and 4000 came with a 110MM pulley and a 90MM pulley. I used the 90MM pulleys because that's what was on the motors from the factory.

I bought a Consew servo motor, it was a 3/4 hp but a different number. It starts real quick, I had to put a smaller pulley on it and a longer activator arm and it is still hard to control. If I buy another it will be the Sewquiet The slower you set it the less power it has so at the lowest setting it will not turn the machine over.

The term "servo" has been bastardized pretty badly when talking about sewing machine motors. A true servo motor has constant torque throughout the speed range, and should run the machine even at it's slowest setting.
