chawkiz, maybe this is unipolar stepper motor (8 wired) http://www.stepperworld.com/Tutorial...arTutorial.htm
stepper motore 8 wire need pinout thanks
2-Phase 1.8 Deg/step
DC 5V 1A
did have chose to make this stepper unipol or bipol
thanks for help

Eight wire steppers can be wired any of 4 ways:
2. Bipolar Series
3. Half coil
4. Bipolar Parallel.
Unipolar wiring will give the least torque and speed.
Bipolar Series will give full rated torque at very low speed, but will not run very fast.
Half coil wiring will give slightly less speed and power than Bipolar Parallel.
Bipolar Parallel will give full rated torque at low RPM, but carry some torque to high rpm. This is generally considered to be the best for CNC.
So which way do you want to wire this motor?
thanks for replay
i need uses this motor to uses with pminmo interface
but (pminmo uses 6 wire 2 wire for V and 4 input
haw configire my stepper 8 wire to work with this interface i need it fast speed
PH265-E1.0B - discontinued product and data sheet not avaliable
Color marking wires new SM Orientalmotor is differs and is found on page 189 catalogues http://www.orientalmotor.com/product...A/St2Intro.pdf
You it is necessary to limit the current, for instance laboratory power source, install the controller in mode of the full step, tax signal STEP low frequency (5-10 Hz) with generator.
You it is necessary to connect coils two by two "begin-end+begin-end" and on average points tax + Vmot supply
Hereinafter connect variants wires SM until will be an even rotation.
The Half an hour of the work and you wait the success!
There is suggestion that
black - begin coil
white /black - end coil
RED- begin coil
white/red end coil
(or on the contrary "end - begin"), but equally on phases coils

ok i used this photo its wrong or ok ? see attach
If you have selected the proper wires, then an ohmeter should show the SAME resistance between black-yellow, orange-green, red-white, brown-blue. There should be DOUBLE that resistance between black-green and red-blue. (The colors are different on your motor, you will have to find these wires by experiment.)
These measurements are taken without any wires connected to the motor.
veryy thanks for help
i have external power with 12 v 1A
the internal resistor on stpeer is 6 ohm per coil * 2 = 12ohm
(12 ohm) resistor motor and external power 12v 1A
motor 5v 1A
waths i uses for resistor ?
12v-5/1 = 8 om *2 = 16 ohm because i used tow coil ?
Careful! A unipolar driver only powers ONE phase (2 coils) at a time and only ONE 6 ohm coil in the phase (per direction) at a time.
but What's Wrong With ?
Nothing wrong. I'm just saying One 6 Ohm coil is all that will ever be powered at once from unipolar. NEVER two at once.
"8 wired , 4 coil" -> "phase A begin-common A-phase /A end" and "phase B begin-common B-phase /B end"
yes, consider resistance of the stepper motor 5V/1A=5 Ohm not it's correct, it's wrong.
