Re: Sigma stepper motor info

Tim:

Searching the files for the information is one option (I have
information posted on Sigma NEMA 42's with 8 connections for
instance).

I found out the wiring diagram for my unmarked motors by tracking
down the appropriate tech support department:

Pacific Scientific bought Sigma and was in turn bought by Superior
Electric. Superior Electric has been bought by Danaher
Corportation. If you call the tech support department of Superior
and ask for an "old timer" who might be able to find the paperwork
(yes, paperwork!) on the Sigma's, you should be able to talk them
into faxing them to you. The following are the web addresses which
should help you find their tech support department.
