Based on the form factor it wont be higher than 1.5A tops, probably around 1A.


360/1.8=200steps per rev.

What else are you looking for?

i want to buy some power supply for them, i have a L293D chip, is it good for controlling nema 17? i have some difficulties

No, a quick google shows that chip is only good for 600ma, better bet would be a L298 Dual H-Bridge Motor Driver, it can do 2A, and power them with the 5V output from a standard ATX pc psu.
