How do you calculate the current drawn by a stepper motor.
Given the (crude) illustration below. I measured the
current through the common lead of winding #1. ( .47A )
Is this the motor current as specified by motor drivers
or do you double it to account for winding #2 ?
Also, is the motor current as specified on the end of the
motor the current through one winding, one side of one
winding, or the sum of all of them?

I'd rather not figure this out by "smoke-testing" several $185.00 motors!
Thanks,
