Epilog Rotary Motor Part Number
The PH265M-33-C9 is actually a proprietary custom motor that we designed and built for a machine manufacturer. We do not have any standard products that would be a direct replacement. For direct replacements, please contact the maker of your machine. Please see below for our closest standard motor and its spec link. You will have to compare your motor and our suggested motor to determine if it will work.

About 6 Wire 2 Phase Stepper Motors
A 6 wire unipolar motor has 2 pairs of two coils. The two coils in a pair are internally wired in series and have 3 external wire connections: one for the end of one coil, a second for the opposite end of the other coil, and a third for the middle (common) connection. Wires for one pair of coils is usually black, yellow (common) and green, the other coil typically uses red, white (common) and blue.
Epilog Rotary Motor Connector Pinout
A picture of Epilog’s rotary connector is shown. It is a Molex 8 pin connector with 7 of the 8 connections used to couple into a 6 wire unipolar stepper. One pin is unused.
Connector Pinout
The color codes are standard 6 pin Color Code 1
Troubleshooting Connections
Your colors may differ or the same colors might be used with different internal connections. Quickest way to find the right connection for your stepper is to hook it up and try it. The rotor should step the same direction each time the voltage changes, resulting in smooth rotation. If any of the motor wires are hooked up wrong, sequential voltage changes will sometimes cause the rotor to reverse direction and you’ll see it doesn’t turn smoothly.
No harm will be done to the motor or circuitry, but you’ll need to switch wires until the rotor turns smoothly in the right direction. Call the 4 coil wires M, N, O and P (you can pick them randomly, just stay consistent) and jumper them to the connector pins 1, 2, 5 and 6 . If the rotor doesn’t turn smoothly (one direction or the other), power down and switch the last pair (M, N, P, O), then try again.
Still not turning smoothly? Power down and switch the middle pair (M, P, N, O). When you get an arrangement that runs smoothly, note the direction the shaft is rotating. If the shaft is running the direction you want, you are done, but if it is running backwards, power down and switch ALL FOUR connections (ABCD -> DCBA).
We make every effort to ensure the accuracy of this information but can’t guarantee it. Verify the data yourself.
