did anyone use the bipolar-uniploar stepper motor below?
AIRPAX (USA), model:SMA 82805 (n.8845)
Volts:4.6
OHMS/COIL: 5
STEP ANGLE : 7.5
I would be grateful if somebody gives me further info about it ?, for exemple, what is the ideal voltage to use ?, the maximum current in the windings , is this correct Imax=4,6/5 ?, what is the value of the chemical capacitor to put next to the L298 (to supply the stepper with current) ?
Did that come out of a copier I have 1 I removed from a copier. It was 24 volts. I would say AIRPAX was a reseller of that not the maker
Look here **broken link removed**

I looked at it it was 12 volts the 24 was for the lite in the copier. hope this helps you out
burt
Yes, with steppers you want to hit them with a higher voltage than what it says. The rating is for a steady-state DC, but you will get crap performance out of them if you try to pulse it off that low of a voltage.
I wouldn't run it at 24 volt. Run it with no more then 12. Like i said I took 1 out of a copier It was being power from 12 volts which is more then it's rating I thought it was 24 but I looked at the power supply that i saved and it was using 12 volts
thanks for this quick reply.
I was told, months ago, that the pulse width of the clock signal entering the L297 (with a 50% duty cycle most of the time) , don't has an effect on the motor , am I wrong here ?

I read somewhere on the internet, that the stepper motors in general can be run with power supply up to 8,10 times the value indicated on them ( rating is for a steady-state DC as said duffy) so that the current on the windings will decrese proportionally.

You can run them at higher volts It give you more power. But how are you going to use the stepper say that you run it at 50% duty a 5volt could run at 10 and not burn it out but at 100% it wounldn't last long. you use the higher volt for more power at less duty
