Hello Friends,
I am a big fan of arduino and I am really new to Arduino.
I have a stepper motor(NEMA23 270 oz-in) with arduino UNO and Easydriver.
Stepper motor's rated current is 3A and rated voltage is 3V.
I have read some articles and got to know I won't be able to handle 3A NEMA23 with Easy driver.I am so sorry about to hear that.So I decided to ask it from you guys.
Is this really true? can't I run this stepper motor from easy driver?
Please Advice me
Thank you
Have you looked at the specifications for the Easydriver?
If so, what do you think the answer is?
If not, why have you not looked up the specifications?
The Easydriver can supply 0.75 amps
The BigEasydriver (and Pololu A4988) can supply about 2 amps
The Pololu DRV8825 can supply about 2.2 amps
For a 3 amp motor you need much more powerful driver. I would choose one that can manage 4amps or 5 amps.
Look at stepper motor basics

No, you just need one that can handle 3A. But it must be engineer's amps, not marketing amps!
One of the smaller Geckodrives might be a possible: http://www.geckodrive.com/geckodrive-step-motor-drives/g251x.html
The alternative is to make your own from discrete MOSFETs, but its not trivial... The Gecko
drives are very cheap for what they are, believe it or not.
Incidentally you won't get 2A continuous out of an A4988, it'll melt first.

That is not the view here.
I am not trying to cause friction between Forum members - just to get the correct info. My motors only need 0.33A so I cannot do any tests myself.

Thank you very much all of you guys.I decided to bought a stepper driver of TB6600 IC. Thanks a lot again for your great advice.
