Choosing a Power Supply for Your Stepper Drive http://lnkd.in/bKE5v4G

Yeah,i got it sir. If i use 0.7Amp/phase means, based on your white paper concept. Then it will (0.7/2)+1 gives 1.35amp . Is it correct sir?. Please say me the solution sir that whether I have to use 1 amp OR 2 amp input supply of stepper motor.

Yes, the equation is correct if you select a regulated power supply. If your stepper drive has idle current reduction, then I would recommend a 2 amp regulated power supply. If your stepper drive does not have idle current reduction, I would recommend a 1 amp regulated power supply.

I don't have regulated power supply,I must design it by using 2Amp transformer. Moreover , 1) How to find idle current reduction sir
2) am going to use TWO stepper motor of same specification as mentioned above, then whether 2amp transformer is enough OR we need 4 amp transformer sir
