edited- I made a mistake with the number, but I'll leave the rest of the info here...
HI,
I have checked 'all over' the web, and can't find any websites with info on an old servo I'm tempted to replace.
It's a Pittman 19203 D173, DC 24 volt brush servo, 500 cpr encoder, 1/4" shaft, 54mm OD of case, 112 mm long overall inc the encoder.
Sorry I misread that- it's a 14203, but it was smudged & faded on the label so the 4 looked like a 9.
As well as I can see, it is very similar to the newer Pittman 14204 S006 in every way, but I can't find out what torque ours is, or was supposed to have.
OK I have now found the torque- 21 oz-inch.
I cannot find any internet references to 19000 series servos at all- they stop at 14000. Ours is 1995 vintage, I think.
That's irrelevant now.
There's a multitude of 14000 series servos on ebay, but most are much less in torque, or have a smaller shaft, or a different encoder and lesser or much greater torque, but some could be close if I knew what torque ours was.
(it drives the Z axis of a router, with a 3 hp Perske spindle, via a toothed belt and 1:2 reduction & an acme screw.)
Any info would be appreciated, thanks!
