Q1 - BLACK
YELLOW (common)
Q2 - GREEN

Q3 - RED
WHITE (common)
Q4 - BLUE

Hm. I couldn't see in the specifications if you can use it in bipolar configuration (hybrid), but I found this similar one which is labeled as hybrid: Applied Motion 4023-820 — it's on sale for $18 on the manufacturer's site (I'm not allowed to add links, sorry).

What's your opinion?

Thanks,
Miki.

The Contribute page needs a refresh.
This is the motor: http://www.alltronics.com/cgi-bin/item/25M002/55/Applied-Motion-Products-44A501711-unipolar-stepper-motor
If you search for part number 44A501711 on ebay, you might find it cheaper.

I found a web site (www.alltronics.com) where they sell stepper motors, but I am not sure if it's really the one that the line refers to. There are several NEMA23 motors there, but none for $10.

In general, have you guys found some reliable, and not too expensive motor you would recommend? So far I ordered all my materials from the sources recommended in the part lists, and I was very happy with them. I have great confidence in your selection of sources. :-)

Thanks,
Miki.
