Stepper Motor drivers
I've been lucky/unlucky enough to have been given about a dozen Stepper Motors, most of which are Sanyo Denki Step-Syn DC rated at 2A, from what Iv'e been able to find out these are 24V. There are 6 wires that are connected to the motor? What sort of driver board? would I need to run/drive these, please?
Thanks,

Kryn,
Can you post a photo?
Are they round or square?
What do you want to do with them? CNC machine?
Unfortunately a lot of older / hand me down steppers are often not ideal for a lot of uses.

Help finding information on Sanyo Denki "Step Syn" IBM stepper motor
Are these the same or similar?
Should be useful for a project of some description.
Have you made any progress?
Steve

Sorry Steve, they're not the same. Will post a pic tomorrow.

I suspect from the name that they are old round ones.
Unfortunately, the ferrite magnets in those tend to die after 5 years or so. The motors may still spin with the right drivers, but they may have very little torque left.
And I have a drawer FULL of old round steppers ... damn it.
Cheers
Roger

Thanks for the reply Roger, most of them are square about 50mm, will line them up and take pics of the details. I think there might be 2 round ones in the lot.

Here are the pics of the motors, hopefully someone will be able to tell me if they are of any use. If anyone is able to use a couple let me know.
COP only, (Cost Of Postage) Sorry no pulleys or gears ATM.

They all look like useful motors Kryn. You can pretty well ignore the voltages, but the Amps are the important data. The higher the voltage you apply, the faster these motors will run, as long as your drivers are current limited to the Amps given on the motors.
What are you intending to use them for?Cheers, Joe

Hi Joe, biggest problem I have is to find a driver to suit the motors?? Am/was planning to build a CNC machine to make Tractor Wheels as in the Toy Making section of the Wood Workers Forum. Then to get someone to hopefully wire and show me how to get it going!!!
I'll only need 2 or 3 of the motors I hope, so if you could use one or two, let me know.

You could try one of these: BIG Easy Driver Board A4988 V1 2 Stepper Motor Driver Board 2A Phase 3D Printer | eBay to start learning or go to one of these http://www.ebay.com.au/itm/171885898820 for a more robust version.
Designing a CNC machine of any kind is going to be a big learning curve.
Once you have a driver, you then need hardware to command the driver with step and direction pulses. That in turn is controlled by software, e.g. feeding it G-code. To make G-code from a drawing, you need CAM software to read your CAD files....
And then you have a computerised numeric controlled machine tool
I take it you want to build a 'live tool CNC lathe' or a CNC lathe that can do some indexed milling (hub caps and tyre treads etc). So you will need a stepper motor for the spindle, tool positions (Z axis, Y axis), tool angle (A axis) and tool roation (maybe a small router motor or Dremel). So I see a 4 axis machine = 4 motors. Plus a few spares for experimentation. So don't give any away yet
Start corresponding with a couple of woodwork CNC guys. That's way out of my area of knowledge....Cheers, Joe

Thanks for all the info Joe, most of it I was aware of. I'll put a copy on the WWF site and see what answers I get.

Hi Kryn,
In that very first picture it looks to be a controller for the stepper motor at the side of it. All you will need to do is find out what the feed voltage is and what signals you need to turn it on, direction and speed.
All the motors that you show should run from that controller and the wire colours are probably the same for all of them.
I have some that are salvaged from a photocopier, you cannot stall them without using pliers on the output shaft. They are driven from a 48-50 volt supply though the markings indicate 24 volt ratings.
I'll take some pictures when I get chance. Currently have Daughter and family visiting.Best Regards:
Baron J.

Thanks for that info Baron, electronics and me don't mix, but I'll try.

Promised Pictures.
Hi Kryn, Guys,
Just a few pictures of some stepper and servo motors salvaged from photocopiers and printers, as promised.
img_0304.jpg img_0303.jpg img_0302.jpg
The first two pictures show a stepper motor salvaged from a desktop scanner. The motor is 1.3 inches in diameter and drove a gear attached to a toothed belt, this in turn moved the scanner carriage back and forth to scan the image.
The third picture is a stepper from a printer. This one drove a belt directly which had the print head fastened to it.
img_0297.jpg img_0298.jpg
These two are stepper motors with external rotors and have built in controllers. There is also a micro processor built on the other side of the board with the power control components on the top. You can identify them by the heatsinks.
img_0299.jpg img_0301.jpg img_0300.jpg
These three are servo motors. Again they have micro processors built on the underside of the PCB. Again they have external rotors.
The lower five motors use 5 volt logic signals to control them and are rated for 24 volts feed to the motor.Best Regards:
Baron J.

Thanks for the pics Baron, you reminded me that I have a heap of them also, mainly from printers again. Pulled them apart mainly for the plastic gears, toothed pulleys and toothed belts. Don't know if I'll ever use them all, but someone one day will ask for some.
