Question About Servo Motors

[dscheidt]

I have a motor that's visually identical to the one under discussion here. It's a different brand, and attached to a garment sewing machine. It's not as sesnitive as this one seems to be, but it's a bit more touchy than I'd like it to be. I suspect it's just a crappy design, or the wrong optical sensor used.

I found that adding a piece of paper (taped to the moving light blocker) could help do the trick. ... you can desensitize the servo pretty much to your liking!

Dave--Thanks SO MUCH for this post. It set in motion a chain of events that lead to the taming of the 'ramp-up' speed on my SewQuiet 5000 servo motor, thanks to Larry at Southwestern Florida Holsters who spread the word.

Larry posted a 'how-to' on his website. I now have speed control from "1" to the maximum programmed speed OVER THE FULL RANGE OF MY SPEED CONTROL ARM, not just that first 1/4" of travel. I did it a little differently, using an opaque piece of plastic cut into a shape that gradually blocks out the light over the full travel of the control arm, but the principle is the same. (details at the end of this thread on hotrodders.com).

...and now the circle is complete!

Again, thanks a million!!
