Anyone recognize this motor?
There are no markings or words. Just a stepper motor with 6 pins. I need a replacement but I don't know what to buy?
Any help or links to a new one?

Measure it, if it is 4cmx4cm, just buy a standard NEMA17 to replace it. I sell them on Ebay for about $20
Finding the pins are very easy... Just use a multimeter.
Use the circuit tester beep.. Connect two of the 6 wires to the multimeter and turn the motor by hand - if you don't get a beep or circuit closed, then switch to another wire..
You are looking for the 2 pairs you need, 1A,1B - 2A,2B. Keep trying pairs until you get the beep.Hex3D - 3D Printing and Design http://www.hex3d.com

42.28mm X 42.28mm X 34mm is what my calipers are giving me.
34mm is the length.
So will yours work?Last edited by BLKKROW; 12-01-2014 at 10:43 PM.

Yes but I only ship within Australia sorry, too expensive otherwise.
These guys ship world wide tho, they have good feedback

Well Geoff,
I got a replacement motor, but when I place my printer into Jog Mode and try to utilize the new motor it isn't working correctly.
Instead of the armature spinning in one direction, it just spins one direction then the other direction like a jiggle.
Any suggestions, I really need my printer and am getting really frustrated.

Are there six wires in your original connector wire?
Are there six connections on your new motor?

Yes and Yes.
I presume the wiring is the same. Also spinning the armature on the new motor is fantastic nice and smooth. While the old motor is very difficult to turn by hand and the bearings on the inside spin freely so it may have something to do with the magnets?
After playing with the old motor it is spinning more freely now.

you need to measure the resistance between the connections on the new motor.
http://www.talkingelectronics.com/pr...pperMotor.html
Just down that page a short way is an explanation of the difference between 4, 6 and 8 wire steppers. You can see that centre to outside will be half the resistance of outside to outside. Using that you can draw the wiring of the pins for your new motor. Repeat for the old motor and see if they are the same.

I appologize for the late reply, my friend had my multimeter and recently purchased me another one to use.
When you say Circuit tester, the functions I am using is the continuity test.
Is this correct? Also I do not know what you mean by the 2 pairs, 1A, 1B -2A,2B. Can you explain further?
