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......

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?

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.

Steppers and EMF.? Answered

I have build this Bi-Polar stepper circuit and it works great on the bread board. I etch a board 3 times, 2 with heat transfer and 1 with photo resist. I use 2 completely separate power supplies but with the PCB's i think i am experiencing EMF or feed back. I am using an adjustable schmidt trigger for the clock. What happens is i can hardly get any rpm's, sometimes if the trigger is set just wright it will turn up fairly well, at that time if i try full step the stepper stops turning or will reverse sometimes, if i try ccw it may or may nor reverse and i may stay in what ever direction and any given time . Now at a slow rpm full step normally work's and cw/ccw may or may not work, also it can trigger the half or full step. Also i can disconnect one coil and the stepper will continue to turn, If i try that with the other coil the stepper will stop. So it looks like it is only running on one coil. Is that possible? Keep in mind i have bread boarded it and work's fine. Its just on the 3 pcb's that all this happens. As for the diodes it seams to work better with 1N4001's than 1N4148's I have checked every trace with an DMM and made sure they are going to the correct pins ect. I have tried different IC's L297 and L298 and steppers 2 different kinds and multiples of each. So i am thinking this is EMF, feedback, or a design problem. I have tried to eliminate most every thing i can think of. Comments?

When the servo turns left, a crank will turn of a fixed amount of degree in the clockwise direction. When the servo turns right, a crank will turn of a fixed amount of degree in the anti-clockwise direction. The main advantage of this is that we can have a stepper motor created with a servo.

Stepper Power Help???

I trying to design a cheap & easy (not ideal) bi polar stepper driver using the following components: 1. (1) A Bi-Polar motor rated at 12V 1A. 2. (4) 10A 250V Dual Throw, Single Pole Relays. 3. (1) Arduino UNO Microcontroller. 4. (1) ATX Power Supply. I have the switching logic all correct from the UNO to the relays, and I have all of the wiring correct on the power side of the relay. The problem comes down to shorting the PSU.My thought is the following, and I hope you gurus can either confirm, or correct my thought process (pretty please, and thank you). Please see the Attached Pic for a basic schematic of what I'm doing. 12v = 1A * 12OHMS 12v * 1A = 12 Watts Does this mean that somewhere within the power loop, I need a 12 Watt 12 OHM Resistor, to eliminate shorting out the PSU? If this is true, what would be a practical solution other than using a big exposed spring, bar, etc... that would by its sheer mass resist all of this power?

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!

Overheating stepper shield

Hi Everyone, As I'm a newbie, please forgive my ignorance for asking what maybe an obvious question.  I've got an Arduino Uno and a DK Electronics v1.0 motor shield (powered separately at 12v). I downloaded a library and managed to get a NEMA 23 stepper motor working. Trouble is, the chip on the shield doing all the work gets scarily hot in next to no time. The rated current of the motor is 1A, although when I tried it, it was under no load. I've checked the power consumption when driving the motor from a standalone controller and it's drawing no more than 250mA. Do you guys think:- a) I'm overloading the shield? b) I've got a fault? c) I scare too easily? Any feedback will be gratefully received. Thanks

Controlling 6 steppers for Orrery

I'm currently designing an orrery planetarium and my current mechanical geared design is rather dense (See attached images) takes up a lot of space, and would involve a lot of gear fabrication. So I'm wondering if I can use 6 stepper motors to run the system and do the ratios in code. If it helps reduce the cost, size, and adds more control options (like inputting a specific date and having the planets move to it) it could be worth consideration.I'm just currently unsure of the best way to control 6 steppers. I'm looking into an Arduino Mega for starters, but I'm not sure how much I/O I can get away with. I plan to just do tests with one motor at a time until I've got six running.The good news is the inner orbits are a smaller diameter involving fewer rotations per orbit and while the outer rings are larger and although they require more rotations per orbit, they move much slower. I can probably find a way to add limit switches if necessary and the I/O allows it, which might be nice for calibration. I don't see this as something I'll be running all the time, since I could see it needing a power supply and long term continuous operation may not be possible with the motors. I'd be open to using servos instead if they could use fewer I/O pins and still rotate continuously, but I'm still doing research. I'm open to any suggestions, ideas, or criticisms for this approach and any assistance is appreciated.For now, I'm still in gear land.

I just don't want to invest time  to solder it only to have it not work.

Stepper Motor and an L298 Module? Answered

Hello, I bought those items: L298 Module Kit, PIC16F877A + KIT, a stepper motor my friend found in an old printer (with four wires (2 coils)), and the pic programmer. I am lost trying to find out how to wire this thing. Can someone tell me how to connect the L298 Module with the Pic kit and the basics of how to program it (not code just the concept). I already connected the stepper motor to the coil pins of the module. Thanks

Program a stepper motor (arduino)

Hello,For a future project I will use some stepper motors but I don't really know how to program them (in C++ arduino) in order to make something like that :one pulse cwdelay(x)one pulse cwdelay(x)...what I don't know is how to code the "one pulse",the goal is to make 4107 pulses in 24hI hope I was clear :) I don't know if it's important but it's a 28BYJ-48thanks !

Stepper motor voltage too low? Answered

I'm getting started with Stepper motors and I got one on ebay, it's MINEBEA NEMA23 2.5V/1.8 AMPS 1.8DEG/STEP (model# 23LM-C045-01H). I'm a bit confused by it's low voltage. Am I reading it correctly, it's 2.5Volts?  Stepper driver that I have requires at least 8 Volts (it's Arduino with rugged motor driver shield), so is it safe to drive with motor with voltage of 9 or 12 volts?  How would one drive such motor at 2.5VDC?
