Family Sew Fs 550S Motor

[Art]

Has anyone tried one of these motors. How about a review? One thing I like is the dial instead of that LED race track thingy for speed control.

I love it. Made small mod to it. I did a search for Fs 550S and found some who also had the servo. I liked it so much I bought an extra...

Art, I made an error. I have a KM-550. Sorry. I think they are the same thing, but I can't verify.

I too have a dial motor.

It runs Pfaff 335 at the lowest speed with a small pulley and I can do single stitches.

I have one. The dial works great, I can quickly turn my speed up to wind bobbins, and down to sew intricate projects. When I sew long things like belts and guitar straps, I put it on a middle of the road speed, and I can feather the foot pedal to sew slow at first and around corners, or go full speed when I go down the long straight stretch. It is quit, and doesn't weigh very much.

Here is a quick cell phone video I did on mine. You can see how fine the dial adjustment works. These were pedal to the metal, speed changes were all dial based. This was fairly hard leather, so it couldn't slow it down as much as I could on fresher leather.

I have two FS-550S motors, both equipped with a non-standard 50mm pulley and multi-position speed limiter switches.. One is on a long body Singer walking foot machine, direct to the flywheel. The other is on a Cowboy CB4500, feeding a 3:1 speed reducer.

The Singer can be operated (sewing belt leather) at a steady pace of about 1.5 stitches per second, with the switch in the slowest position. Moving the limiter up adds more top end and makes it a tad harder to sew at the slowest speed. I can set it to full speed and still feather it down to about 2 per second, depending on how much coffee I have had. With the pedal down, at top speed, the walking foot machine flies along at about 20 stitches per second.

The Cowboy can run at just under one stitch per second with the pedal all the way down. I use this setting to sew fishtails onto belts. Backing off the pedal, I can carry on a conversation and watch the needle move. I recon that it is moving at about 1 stitch every 9 seconds. With the switch set to full speed and the pedal down, the Cowboy sews at about 5 per second.

Wiz,

Are they brush or brushless?

They have brushes, and they come with extra brushes

I don't think I waited long enough after uploading before I tried to copy the link, so it just copied the list page link maybe.

Not only do they have carbon brushes, they also come with a spare cork brake. It is a little tricky to adjust it and some people remove their brake entirely. If you do that you'll have to use your right hand as a brake.

There is some variance between these motors. My buddy with a Cobra Clas 4 had me install a FS-550 on his machine. Without any tweaking he has 1/2 inch of totally free motion between the brake letting go and the motor powering on. I can't seem to get anywhere near that much on mine (sigh).

Thank god for this thread and thanks so much for that video!! I plan on buying this servo as well to install on my consew 206rb I'm set to pick up Wednesday on Craigslist. Right on time!
