That motor was the SewPro 500GR (I have one). About 3 or 4 years ago, after changing the metal the body was made of to aluminum and cutting the top speed in half, causing all manner of problems and complaints from users and dealers, the employees at the factory that built nothing but that motor went out for lunch and never returned.

Hi Wizcraft,

 

So there is no chance of getting a SewPro then... That is a shame....

 

I am making gloves and I really need a slow motor...  Any suggestions?

 

Cheers

Hi Alex,

talk to Frank Brunnet. http://www.frank-brunnet.com/ He is the Cowboy Bob of our side of the pond. I will probably get one of those  http://www.ebay.de/itm/leiser-230-V-Motor-800-W-passend-für-Industrienähmaschine/322847634323?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649  in the next couple of days.

Hi Ralf,

 

Thanks for the contact, I had never heard of him.  Do you know the minimum speed of that motor?  I will be interested to  hear your opnion of the motor should you buy it.

 

Cheers

Well, I remembered that I had an old Pfaff motor like this below.  Surprisingly I am able to feather the pedal so that I can sew slowly.  Admittedly I cannot control exactly when it stops, but in such cases where I need precise control ie when sewing the finger tips, I can turn the wheel by hand for several stitches.

 

I have only ever used servo industrial motors, but I might consider using induction motors from now on.  This is not ideal,but then again I cannot find an ideal servo motor either...

These motors are not bad! Especially for lighter applications - but when you sew slow all the time they tend to become "quite warm" and you can smell it. however they are really nor bad!

I can't read the spec. plate, but that looks like a brush-type motor. The screw at the top looks like a brush-holder mount, in which case it's the same type as found in electric drills etc. (not induction).

Hi Ralf,

 

Thanks for the reply.  I got a response from the seller and it seems like the whole range JM700-900 has a lowest startup speed of 300 rpm.  This is a surpise since sewtex are advertising the JM700 as starting at 100 rpm..

Hi,

 

this appears to be the motor Sailrite is demonstrating here against their MC-SCR-system. They stopped the sewpro - set to slow sewing - with one finger.
