Datenblatt/Fabrikat für Motor gesucht

Could you please rewrite your post in english?

I think you want to build a stepper controller.
Maybe you check out the old workhorses like L297 and L298 to do that 
job. Theyre quite cheap, too.

The motor looks like salvaged from a scanner or printer or so.
With a multimeter you can easily measure the inner circuit and whether a 
bipolar or unipolar driver is needed.

Instead of using a malformed automatic translation into german you'd be 
better off asking in english.
I can't answer your question in italian, sorry 'bout that.

Non parlo italiano

regard to the whole forum...

I am had to make to work it with a controller simple driver.
you can help to recognize me the datasheet and the factory of this motor
in photo the enclosure?
I have to make to work this motor QH4-4300-01 with three simple 
movements, before - back and adjustable speed with a controller driver. 
however I need the factory, datasheet voltage.
it has 4 cables, 3 grey and one blue. which is the scheme link wire to 
feed it?

possible it owes what controller driver acquistared for those functions
simple.
in the meantime regard and I thank, confiding in one help of yours

If you would have taken a closer look on the sticker on the motor, you 
should have seen hat the maximum average current per coil is 700mA. The 
voltage of a DC source is 1.8V then. The resistance of one coil should 
be near 2.5Ω.

Four wires...seems like a bipolar motor to me.
As I said before, a multimeter or continuity buzzer can easily point out 
which wire goes where.

Yes.. the homework assignment, has to turn to walk before and back and 
to regulate the speed. you can give me you the datasheet volt power of 
this motor, capico alone angle deg 1.8 of steep, 1,8v and 0.7A. which 
driver controller do I have to purchase or to build?

hi STK500-Besitzer..
respectively 1 = grey, 2 = grey, 3 = grey, 4 = blue.
now, cable 4 with cable 3 are open. cable 4 with cable 2 are close. 
cable 4 with cable 1 are open. cable 1 with cable 2 are open. cable 2 
with cable 3 are open. cable 1 with cable 3 are close. the ohmeter not 
to give any measurement of impedance, but only open or closed.

A typical driving pattern for a stepper motor looks like this:

Forward:
Voltage Coil1: 0 + + + 0 - - -
Voltage Coil2: + + 0 - - - 0 +
         Time: 1 2 3 4 5 6 7 8 1 2 3 ...

Backward:
Voltage Coil1: 0 + + + 0 - - -
Voltage Coil2: - - 0 + + + 0 -
         Time: 1 2 3 4 5 6 7 8 1 2 3 ...

This can easily be achieved with a decimal counter and some glue logic 
or a decoder made with a diode/resistor matrix.
The output of your logic circuit should be four signals, two for each 
H-bridge. One H-bridge is made with four bipolar transistors(so you need 
eight, four PNP and four NPN, maybe like 
http://talkingelectronics.com/projects/200TrCcts/101-200TrCcts.html#29).
I recommend to put a resistor in series with the coils, because of their 
low resistance.

regards, mf

PS: Forward/reverse can also be achieved by switching one coil's 
polarity with a relay or inverting the control signals for this coil.

Found one coil!

Congrats, you found the other one!

You don't have to go to University to make this work.

I also had such a project like yours in my early days.

It looked rather similar to this:

All these snippets fit together like Lego Bricks...

The "mshield" only works with an arduino or other microprocessor boards, 
there's no control logic on it. Everithing has to be done in software.


You wanted a more standalone solution, why don't give the "Big Easy" a 
go.
Switches for direction et cetera are still missing.
Just wire them like in my post above.
I don't believe that it can do 2A, but since you only need 700mA...

mf

PS: manually clocking 3200 steps/revolution for microstepping seems a 
bit boring to me. just google how an additional 555 clock generator can 
be made.

All we got is malformed english translation... ;-)

With your level of knowledge this is a demanding task... :-o

Why don't you just write, WHAT you want to do with this motor?
Do you want to run a robot? Or what else?
Do you have any knowledge in electronics?

Ja, ich hatte ja gehofft, daß er statt einer automatischen Übersetzung 
it-de selbst in en schreiben würde, aber das sieht irgendwie immer noch 
nach einer automatischen Übersetzung it-en aus.

Die aber ist immerhin verständlicher als die it-de-Variante.

Also schlimmer gehts echt nicht, da werden unzählige Lösungsvorschläge 
gebracht und der kommt jetzt wieder angesch***en mit basic knowledge. 
Wenn er das hätte, hätte er nicht hier gefragt.

dear "work-it"
1. please stop translating with google
2. write directly in english please
