I found this circuit in my files. I don't know where it came from, but it looks like I photocopied it from somewhere years ago. I have been told that it came from "The Robot Builder's Bonanza", by Gordan McComb. Anyway, I thought that it should be fairly useful, so I decided to post it here. The circuit is very simple and inexpensive. This is good thing because most commercial stepper motor controller ICs are quite expensive. This circuit is built from standard components and can easily be adapted to be controlled by a computer. If you use cheap surplus transistors and stepper motor, the price of the circuit can be kept to under $10.

Schematic

This is the schematic of the Stepper Motor Controller

Notes

  1. You should be able to substitute any standard (2N3055, etc.) power transistor for Q1-Q4.
  2. Every time the STEP line is pulsed, the motor moves one step.
  3. S1 changes the motors direction.

I have checked the entire connection, but, I dont know why only 2 transistors are turning on, also no switching happens when i try to switch it. Any help regarding this would be highly appreaciated.

Hello,guys. I think all of you will be interested in a new simple stepper driver IC, THB6064AH, which is more superior than TB6560AHQ. Many guys have tested it ,and have good comments.

If you are finding it hard to complete your own designs there is a company called GPF Engineering that design low cost stepper drivers. Try the link "http://www.gpf-engineering.co.uk/"

I have always thought steppers were too complex, but tried this circuit, using "some" diodes and 4401 transistors, and some stepper motor I have had for years (had 6 wires, checked with a meter and it matched the type used in this circuit). Wired it up, and it just sat there - duh - I forgot to provide a clock. So I wired up a 555 at some low frequency, then used it as the clock. The motor took off running perfectly when I turned it on!! Thanks for sharing!

i have symulated this circuit in multisim with the exact components and it does what the author says. according to the symulation first q4 high next q2 next q3 and last q1. only one at a time. to wire this to a 4 wire stepper you just need to connect the ouputs of the transistor of q3 and q4 together on 1 set and q1 and 2 on the other 2 leads i have to say a very simple but effective disign so thanx to the uploader

I have also built the circuit and was having similar problems to others that have commented. two outputs go High while two stay low and they alternate. I believe this may be a bipolar stepper motor driver and not a unipolar driver even though it clearly shows a bipolar motor attached.

I have your circuit complted and in the debug stage. I have the or gate wired to the flip flop and the flip flop wired to leds. Problem is I have more then one led on at a time. And at each step it seems to be ramdom outputs. I have checked the circuit but I still feel I have a Problem. How should the flip respond to a pulse? Thanks Jack

I can't help but notice that in this circuit has the outputs Q1, Q2, Q3, and Q4. Looking at this schematic and probing the circuit the output in order is Q1, Q3, Q2, Q4. I'm having trouble getting my motor to work with this circuit and I did switch the outputs to the motors to match the output in order as follows: Motorwinding1-Wire1 to Q1 - Wire2 to positive - Wire3 to Q3 Motorwinding2-Wire1 to Q2 - Wire2 to positive - Wire3 to Q4 http://en.wikipedia.org/wiki/File:Drive.png - Look for full step drive Does switching these wires make a difference in the motors function? It did end up working after I switched these wires.

Brilliant demonstration schematic for logic commutated motor driving. Now while everyone is pushing their motor drivers here I might as well throw mine into the ring. It is built with a Toshiba TB6560AHQ and costs about $10 or so to make depending on where you get your parts from. http://www.youtube.com/watch?v=cgbeyNNBZ68 Schematic: http://img695.imageshack.us/img695/5841/tb6560ahqa.png Board Art: http://img819.imageshack.us/img819/4452/tb6560ahqac.png

Thank you for posting this circuit. The simplicity is beautiful, and it's exactly what I was looking for. I hope the "engineering students" posting previously for help were joking, because it would be sad if they were serious. If you don't know how a Flip-flop or an XOR works, look it up! If you don't know the difference between Unipolar and Bipolar motors, look it up! The guy has spoonfed us enough.

The controller on this page is a full step half phase controller only. For (much) better performance, consider a microstepping controller. A good, open source (schematic, code, instructions, etc...) example is the Linistepper. It has full power half step and up to 18th over stepping modes for smooth operation with less chance of a missed step under load. http://www.piclist.com/techref/io/stepper/linistep/index.htm

i dont understand all that commnets 'cause there's alot question but no answer ?_?. this circuit needs more explaination. i'm answering as i know, 1- this circuit can drive directly UNIPOLAR stepper but not BIPOLAR. 2- if you want to drive bipolar u need a "H bridge" circuit. and my question; how sould i wire the unipolar stepper to continuously, step by step move. ( when i wired it randomly it started to turn freakly)

(Editor's notes: As the comments form says, comments really aren't for asking questions. Try posting in the forum.)

Hii i am using the inkjet printer stepper motor(12V and 0.9A) for controlling my robot. But recently my two motors are damaged. I am using Programmable Logic Controller(PLC) to control the this motor and giving the 12 V supply. is it because i give 2A current. Thanks in advance

If the CD-Rom motor has only three wires, then would it be a stepper motor? Just reading this page http://www.flyelectric.ukgateway.net/cdrom.htm here, it would seem as if they arent stepper motors. Try opening broken flatbed scanners, printers, of floppy drives for a stepper motor i think... but i dont have any experience with this

To Santiago: I am not try this circuit yet, but it seems it work. You must know: This is for Stepper Motor, if you want to try, just touch the step to the ground/zero a few times (on-off-on-off-on-off ...) it should make the motor move. If the motor not move in one direction, try to switch the coil connection (A to C or perhaps to B). Have a nice try....

Hello, Do anyone know about any IC which drives a stepper using only two signals (i.e. one for Forward and Other for Reverse) ?? If any one knows the name of IC please mail me...

Very useful. I used this model to design my own in the past. The only thing that should be noted is for beginners. this is that the logic gates and flip flops can be of any variety of logic. you could use a 7486, XOR and a 7476 flip flop. Or a combination. again, very useful, and skips all the crap, going straight to the schematic.

Wow someone posts a schematic (not even his design) and every wants tech support, someone even wants the PCB layout. If you want more current use darlingtons like the 2N6282 , higher voltage just make sure the transistors are rated for it. Usually 30VDC is not a problem. And don't forget those clamp diodes... 1N5819 work well.

The stepper motor that I have takes 4 wires and a ground. Will this controller work with it. What I see this one has is 4 wires with a 12volt feed am I understanding the drawing right.

Is this a Bi-Polar Stepper motor dirver?
Thursday, June 21, 2007 2:32:22 PM
I've been looking for a schematic for a bi-polar stepper motor driver (stepper motors have 2 coils/4 wires as opposed to 4 coils/6 wires). The caption at the right of the coils suggest thata there are 2 coils but it looks like there may be 6 connections to the motor which has me a little confused. THanks!

I want know how to control the resonance of stepper motor when it is moving at low speed? I am getting noise when it is coupled to spur gear at low speed.

I just have 2 questions for you. I was wondering what voltage of stepper motors this circuit could handle. And 2. how would I be able to connect it to an old parallel port to have it controlled by my computer. I'm asking because I'm building a mechanical arm and this circuit may work for what I need. Thanks for the help rockon

Kain, did your analysis show it is a half-stepping circuit or a full step? Any way I could talk you into posting the "output chart"?

It is a unipolar controller. If you need a bipolar controller, this circuit can be augmented with an H-bridge. A quick google seach should turn something up (almost identical to this circuit, iirc).

Hy Balázs! This is Unipolar. Look the 4 pins in PNPs, and the 5th pin the core 12V. 5 pin = Unipolar. Egyébként sok sikert!

Fiebig: I just analyzed the circuit. It does remember its position when reversed. :)

Just wondering how the reverse works with this circuit. Does it remember it's position when reversed? IE: if I'm pulsing the circuit and it moves from position 1 to 2, 3, 4, 1, 2, and ends on 3, then flip the reverse switch, will the next step take it to 2 or does it restart at 4 or 1?
