Greetings all,
I have googled and called the factory. The motors are too old. They
were able to give me specs on one motor in the series but I'm pretty
sure the voltage specs they gave me were wrong. The nameplate has this
info:
Model: E723
Part Number: 0723-08 013
Any help would be great.
Thanks,
Eric R Snow


Eric,

I have a '94 catalog that lists a few 0723-xx-xxx motors, but none with
the same number as yours. And, unfortunately, if there's any sort of
clue to the motor specs in the numbering system, I can't detect it. If
you want a couple pages to look at and have a fax, contact me offline
and I can send them to you.

On the other hand, it's easy to determine the voltage constant (V/krpm)
experimentally, and once you have that you should be able to make a
pretty good estimate of the other specs.

Hey Eric
Either email or call Rick Robison at A&D machinery (Wells Index). Most
of the older Wells Index (Bandits) servo motor CNC'S used electrocraft
servos. He keeps a pretty good supply of them on hand to service all
the machines out there. They retrofit Centroid Controls and keep the
old parts as spares. I've purchased two of these retrofitteed machines
from them and am really happy with them and more importantly with their
support.
