Stepper motor controllers

Does anyone know where I can buy some bipolar stepper motor controllers and an H-bridge in one package? Or even better, schematics/pcb layout of a driver board?UPDATE:Does anybody have any experience with the Easy Driver? It seems like a cheap alternatives to some of the other available controllers, but I just want to know if you get what you pay for.

stepper motor

Wondering if any one knows how to control stepper motors via Hand wheels. By rotating the wheel you should be able to control the rotation of the wheel either clock wise or ccw. I do not want to interface the motor through a computer.

floppy bipolar stepper motor driver? Answered

hi i wanted to salvage my old floppy drive , and take the small bipolar motor from it after i removed it , i looked around and i found small ic (  LB1838M  ) its data-sheet is here http://www.datasheetcatalog.org/datasheet/sanyo/ds_pdf_e/LB1838M.pdf i found somethings (pins configuration) in the data-sheet that i don't understand like :  IN1 ,  IN2  ,  ENA1 , ENA2 so , what this pins represent for ? and , can i remove this ic from the board , and make a circuit like this one in the data-sheet and use it to control the stepper ( independently ) ? if yes , i need to know how to make controlling buttons or something . English in not my 1st language btw , so ... thank you :)

Stepper Motors..

I recently pulled two stepper motors out of a working IBM dot-matrix printer. One larger, 3v one with 1.8 steps. The other is a smaller, 9.5v one with 7.8 steps. I am more interested in the large one right now. I managed to find out that the large one has center-tapped coils. I also found out that Coil 1 is red-white-brown, coil 2 is blue-black-yellow. I found the schematic below on http://ashishrd.blogspot.com/2007/09/computer-controlled-stepper-motor.htmlI was wondering how this could be adapted to control my motor from a PC program with the ULN2003 (that chip sounds like UT2003)? Here are the complete residences of what I found on the wires with a multimeter, in case that helps. Resistances:Red to Brown: 8 ohms (or 7 some times)Red to White: 4 ohmsWhite to Brown: 4Blue to Yellow: 7Yellow to Black: 4Black to Blue: 4

CD stepper motor controlled by PC?

Hello, Is it possible to control a bi-polar stepper motor from a CD reader/writer with the original print board? (so without adding any other IC's), and also with the original flat-cable? I would like to create an XY positioning table with 2 of these stepper motors. I don't understand much about data transfer trough a serial port, so I would like to keep using the original wiring (flat cable) that goes to the motherboard of my PC. Does there also exist software to program a pattern (for drawing an image on the XY table) that sends signals directly to the stepper motor? (trough the flat-cable) ? Thanks in advance, Electorials

Voltage from 4 wire bipolar stepper motor!

I've stripped a 1.8 deg stepper motor out of an old fax to make a bike generator but I can't get any juice from it. I'm spinning it using a multi tool so I should get something, right?! I did do some research and found out that 4-wire bipolar stepper motors are controlled differently from 5+ wire ones. I guessing then that generating power is different also. I'm reading 2.1 - 2.3 ohms off each coil. Tried wiring the coils in series but still nothing. I need a long serving instructablator to help me!!

Well It was a simple two motor set up with a high quitly lens. As I yanked the lens configuration, ever so gently, the horrer poured forth from my face as I realized that even though one of the motors had 2 wires from it, the secound had 4. I have no ideal about motor orvoltage identification. I am so worryed about hooking up any old power sorce and hoping for the best. I really wanna use this lens but don't wanna fry the motors. COuld any one help me out?? I have included a PDF. of the circuit lay out of the camrea itself my GF was so gifted to find and a couple of pictures of the actual motors and wire set up. If any one could tell me what I am working with and what voltage input I need it would be duely welcomed. And if possable would anyone be able to tell me for the smaller 2 led motor as well?? It's got 2334H printed on it and is from the Nihon Mini Motor INC. Thank you......

Hi! I am trying to find a good h-bridge for a 3 volt stepper motor. Basically my plan is to build a stepper motor controller with an arduino for controlling various functions in a model kit. I have the arduino-kit and the motors. But I need a good reference for a h-bridge, but all i can find are chips rated for much larger drive currents. Also exactly how hot does a hbridge get when under load? I would like to integrate the bridges into the kit, but since it is plastic, I would like to know in advance how hot it gets, and if it gets too hot I'll have to look at another solution.Any help appreciated!

Which Stepper motor and which controller?

Hello, Still in research mode for my own CNC machine which will be Arduino based. But, as everyone is using different motors and controllers (drivers?), how do I choose the right one for me? My machine should be able to do soft materials like wood and plexi/acrylic but I als want to be able do mill/cut aluminum, as I am restoring an old car and parts are not easy to get hold off. For my board I was thinking of an Arduino UNO (like most) but then, which motor to go for? Uni or bipolar? 17, 23, 34? And which driver? gShield / CNC Shield V3 / Dual step driver? A4988? 1 board per motor or can I combine them? How to get a smoother run then 1/8 steps? (Found CNC Shield V3.0 + UNO R3 + 4pcs A4988 Driver for £15???) I have never soldered anything, but I am a fast learner. So far when it comes to electronics, I managed to hardwire a stereo without harness into my car, speakers, radiator fan circuit and some door controlled LED's. Far away from soldering of building a CNC, but I am up for the challenge. I know there are a lot of questions in this post, but I appreciate any explanation why someone chose one motor over the other etc.... Any information is highly appreciated. I rather research more then building something and then have to start over again. Kind regards, Red

Need help with stepper motor controlling

Hi guys, I'm trying to build a contraption based on 6 stepper motors, wich I need to control via a Raspberry PI. Since I'm no good with electronics and my friends who might help are unavailable this period, I thought I'd ask around here for some advice/help. I know I need drivers/controllers for the motors, but each kind of motor requires a different kind of driver (based on power consumption, on electronic specs etc.) The motors I'm planning to use are: 42BYGHW811 and 28bygh102 / 35BYG103 (choice made based on needed power at smallest possible dimensions), and micro-stepping is something I could really use, because I need as fine a rotation as possible. So, the questions are: 1. can you point me to the right drivers, to buy? or give me some pointers as to what parameters to look for in a driver for these motors? 2. if not, can you design and build one driver capable of controlling all 6 motors, or separate drivers, and able to also achieve micro-stepping, at a decent price? I'm planning to make this project of mine available as a kit for sale, in the future, once we see it working - so bringing aboard a guy who really knows this kind of stuff is something I'm also considering (as of right now, we're 2 guys involved: I'm the designer and the other guy is the mechanical builder - we still need the electronics guy and perhaps the programmer) Any ideas/feedback are more than welcome!

Audio reactive stepper motor control

Hello, i'm new to the instructables-comunity and i just started to work with arduino some months ago. I've already made some small projects with a stepper motor and a project with a SD-Card-mp3 player for arduino. For my next project i would like to work with audio reactive stepper motor control. To do that, i already bought the SPARKFUN SPECTRUM SHIELD , an Arduino Uno and a hand full of the wellknown 28BYJ-48 Stepper Motors (5V) and the matching ULN2003APG shields. In the description of the SPARKFUN SPECTRUM Shield it is mentioned that it can also be used to control motors (audio reactive). Unfortunately I couldn't find a code or a manual for it yet. The SPARKFUN SPECTRUM Shield divides an audio signal into 7 frequency ranges (bands). I would like to drive 7 stepper motors in combination with the Shield. Each of these motors should move in one direction with constant speed as soon as the respective frequency range reaches a certain sound level.Does anyone know the SPECTRUM SHIELD and can help me? Or has someone already carried out a similar project and can give me some advices? Maybe an Arduino UNO is not enough powered... and I should rather use a bigger microcontroller? I am grateful for any advice. I'm looking for hints on the coding and the wiring.I attached a rough scheme of my planned project.And here is a PDF for the MSGEQ7, of them two are used for the SPECTRUM SHIELD.Would love to get some help from the community!

CNC mill stepper motor controller

Hi y'all from France! I've been aching to get my hands on a CNC machine from quite some time now, unfortunately I'm quite a noob when it comes to electronics and such. I'd found that while the machine itself is not that hard to build (see all the ables), however the electronics involved are just too complicated for me to build a controller from scratch. I've found the other day some seller on french ebay selling a complete controller without the power supply, so I've been wondering about it but am not in the position to fully understand that piece of equipment. So my question is: what do you think about it guys? Does it seems to be ok (BTW I've also found 3 NEMA23 stepper motors, precisely the same model as described in the specifications for the controller board on its seller's page)? For now I just want a three axis CNC machine capable of cutting polymer foam and soft wood, so I don't really need expensive and powerful stepper motors. Thx for any kind of input!
