Stepper Motor Identification

Hello
I have a salvaged sanyo denki stepper here and I wanted to know if
anyone could tell me if it is a unipolar stepper, or if you have a
datasheet for it.

Step-Syn
Type: 103-771-18
IBM PN: 4240593
NEMA 23
1.8 Deg/step
24V
180mA

It has 5 wires, four and what I assume is the center tap. The
resistance across any combination of the four wires is 250 ohms, and
the resistance across the center tap and any of the other four wires
is 125 ohms.


Thanks
Pat

    Hi Pat:
    I have the same stepper motor working in a home maded CNC
    machine.it is is a unipolar stepper
    motor with only one central tap for the two coils.
    I´m sorry for my English
    Regards
    Roberto

    Roberto,
    Thanks. Do you know what its rated torque is?
