     5I have found the [http://www.kollmorgen.com/en-us/products/motors/stepper/_literature/stepper-motors-catalog_en-us_reva-2/ Kollmorgen Stepper Solutions catalog] which has full information on the N series stepper motors. 
     6 
     7So the !PacSci (now owned by Danaher) N31HRHJ-LNK-NS-00 part number decodes to: 
     8 * N=Standard construction stepper motor, N series 
     9 * 3=NEMA34 frame 
     10 * 1=Single stack length 
     11 * H=Heavy duty NEMA mounting 
     12 * R=Regular construction, leadwire (flying lead) connection 
     13 * H=4 lead parallel connection 
     14 * J=Standard winding type 
     15 * L=Laminated rotor 
     16 * N=Single shaft 
     17 * K=Straight key shaft 
     18 * NS=No feedback 
     19 * 00=Standard motor with shaft seal 
     20 
     21NI (National Instruments) [http://sine.ni.com/nips/cds/view/p/lang/en/nid/203938 lists it for sale for $319].

     23== Specifications == 
     24The [http://www.kollmorgen.com/en-us/products/motors/stepper/_literature/stepper-motors-catalog_en-us_reva-2/ Kollmorgen Stepper Solutions catalog] provides specifications, phase sequence information, and dimensions.  I also found specifications on [http://sine.ni.com/ds/app/doc/p/id/ds-311/lang/en NI's web site here].  Here is my summary:

     47||'''B+'''||Red|| 
     48||'''B-'''||Yellow|| 
     49 
     50== Connecting to a Copley Stepnet == 
     51Connecting it to a Copley Stepnet is quite easy (no encoder or hall sensors to worry about).
