I should have looked up your part first before volunteering info. My motors are DC-brushless, yours are brushed, so not related at all. Sorry.

The sound very similar to these old Electrocraft motors I picked up. I'm running mine using some older Technics drives. I contacted Electrocraft about them and they were kind of hesitant to share the info, because the motors were special order for an OE and they said they didn't have the exact winding data to share. But they did give me this (see attachment if it goes through). These didn't have the index brought out either, but by adding the wires to the pin connector in the encoder housing I was able to bring out the index on the ones I have. (It is possible yours could be very different the part numbers aren’t the same.) Todd Zuercher P.

I recently bought a pair of Electrocraft / Reliance ElectricE661 servos fitted with Renco 77678-319 encoders. Part number 661-028-0156 My Web-Fu must be getting weak as I have not been able tofind any real specs on either the servo or encoder. These units are used pulls from some equipment gettingparted out. They are available from multiple sources on ebay and other venues. Theyhave a 3/16” aluminum mounting plate with 2 quick release levers and a toothpulley for a 1/2 wide XL belt Mountingflange appears to be NEMA 34, Encoder shaft is ½” dia. and output shaft appearsto be 5/16” or 8mm ( I have not removed the pulleys.) Removing the encoder cover I see that only 4 wires areconnected to the internal 8 pin connector so no index is being brought out onthe existing encoder wire. Is anyone familure with these. Without specs it is hard tomake informed decisions on how to apply these for best use. OTOH I also recently got a great buy on a 2Nm Stepper withencoder feed back driver kit with all cables for $106 shipped. Now I see theprice has dropped even further.
