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

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.

Arduino + Stepper

Hi! I have an Arduino nano and a Minebea PM55L stepper motor and I have to connect these two together. I read the Arduino tutorials, and got a ULN2003 chip. The thing I am unsure of is the power supply and which wires of the motor do what or should be connected to what. There's 6 of them and I really don't want to fry anything if at all possible. Could somebody help out, please?

alternative stepper motors?

I recently tore into a couple printer-scanners looking for stepper motors. Unfortunately all I found were some DC motors that seem to be tied into some sort of sensor that acts like a step counter. Does anyone know what they are called and how to use them in place of stepper motors for a CNC machine? As a side note, I have a very limited understanding of IC function, think of me as having lived a purely analog lifestyle.

Stepper motor driver?

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! PS. If you can please put the hbridge part ID in your answer for easy reference. DS.

Hi, I recntly took apart a hard drive and there is a 7200 rpm motor inside. Only problem is that it is a stepper motor and I don't have any equipment to drive stepper motors and buying stuff to do is err... cost prohobititve.  Would connecting a negitive wire to 2 of the terminals and positive(in sort of a crisscross pattern e.g. -+-+) to the other make it run like a regular motor? I just don't want to invest time  to solder it only to have it not work.

What Stepper Motor Is This, IF it is a stepper??????????

Hi I am a starting level, I mean mail room like even, electronics enthusist, and have been working on a project to make a wifi transmitted dc motor video camrea, with pan/tilt, zoom focus, IR All controled and veiwed through a wifi network and on a pc. I have almost all the parts and set up is going great with the addition of a Lens I salvaged from an 1984 video camrea, ya know the ones you had to hook up to your vcr just to get it to work. 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......
