I have this stepper motor from this shop, same serial number and same rating but different model from the picture in the page. The model i have a smaller connecter from the motor side and the wires are: Red, Yellow, Green and Blue.
It is rated as follow:
1.8 degree step angle
1.8 N.m holding torque
So I have these questions please:
1- I saw tutorials on youtube with the wires having black as one of the four, the blue wire is the GND on my model which doesnt have black?
2- which driver can i use for this stepper ? example please
3- regarding 1A, so it will draw 1A for it to run at 1.8 N.m torque ?
