Will The $150 Chinese Servo Motors From Ebay Work On An Old Adler 68?

Had another play on mates Consew 206RB-4 today and found I can slow the machine even more now, the Skyrit chingalese instructions were a little vague and I seem to have the 4 button controller not the simpler 2 button one, for programming, but after a bit of frustration I sussed it out, I have the max speed set at 1000rpm, but by feathering the pedal I can hit perfect single stitches every time, and if I need a burst of higher rpm I just hit the + button and can ramp it up to whatever up to 3000rpm in 25rpm increments.

I made the mistake of holding the head pulley wheel as you do with the clutch motor, and boy does this thing have some torque !

Will repeat yet again I am super pleased with this little servo motor.

G'day banjo, all of mine are two button controllers, other than the four button ones displaying a bit more info on the control panel there's not much difference that I can see. I found that the first two parameters, N1 (startup speed) and N2 (max speed) were the only ones that really had any effect. If you fit the needle position device and turn it on then other settings become active, but other than that you can't change much.

I set both of these to 10, I assumed this meant 100 rpm for N1 and 1000 rpm for N2, even though they refer to "spm" in the description part of the table.

From what I noticed if you set the max speed lower then the slowest speed is also lower, i.e. it will crawl along slower. Of course, having a speed reducer fitted also affects things, as 1000rpm on mine will be a lot slower at the needle than on your mates if he has a direct drive.
