6 Wire Motors: With the ohmmeter, separate the wires into two groups of three (there'll be continuity among the three in a group, but no continuity between the groups)
{ed: or use the method above to find the groups without a meter}
As you are testing, make sure that none of the motor wires are shorted together, other than the ones specified in the test.
Arbitrarily label the wires in one set a, b, and c.
Twist together a and c and hold them to one side of the battery while holding b to the other side. Does the motor turn
easily?
- If yes, then b is the center and a and c are the ends.
- If not, then try again:
Twist together leads b and c and connect them to one side of the battery and lead a to the other. Motor turn
easily?
- If yes, then a is the center and b and c are the ends.
- If not, then try again:
Twist together leads a and b and connect them to one side of the battery and c to the other. Motor turn
easily?
- If yes, then c is the center and a and b are the ends.
- If no, then there’s an unknown problem because those are the only combinations.
Repeat the labelling and test sequence for the other set of wires.
(see Stepper Motor Connection Options for all the different ways you can hook your motor up)
Phases:
With a battery, connect the common to one side, Then touch each wire to the other side of the battery until you find one that spins clockwise. Call this A. Pick another wire. If it goes clockwise too, call it B, and so on. If it doesn't, re-apply A, then pick another wire. Eventually you get A,B,C & D, and it should spin clockwise when voltage is applied in sequence. Reverse the sequence, and the motor should go backwards.

Parallel port female pin-out:
D0 is the LSB (Least Significant Bit) and D7 is the Most Significant Bit (MSB). You can send an integer type data to the D0..D7 pin-outs. And the output will be the binary form of the integer we send. For example : If we send an integer data 15 the output will be:
| D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
| LOW | LOW | LOW | LOW | HIGH | HIGH | HIGH | HIGH |
15 (byte) = 00001111 (binary)

Es bipolar o unipolar el nema 17???
==========================
unipolar connect 6 wires or bipolar connect 4 wires and not the common.
Dear cmrv,
Hi, you can go up to 24 volts, I run them at 12 volts .8 to 1 amp. I always start at the lowest settings and work my way up to find the best run. You should be able to go up to 1.2 amps.
Thanks Tony

Dear tony202511,
how much voltage this motors needs to work?
Thanks.

NEMA ( National Electrical Manufacturing Association )
This is a standard of measurments that relates to many items.
You may see in reference to a servos or steppers "NEMA 23" or "NEMA 34" etc.
This is the size of the fixing plate for these motors.
Divide the NEMA number by 10 to get the approx size of flange. (23/10 = 2.3 square)
(Inches)
NEMA Flange-Size / Bolt-Spacing / Hole-Dia.
23 / 2.22 / 1.87 / 0.18
34 / 3.41 / 2.76 / 0.21
42 / 4.22 / 3.53 / 0.27
