From data gathered at the API website it appears that the
proper drive current setting for this motor in a series
configuration is calculated as: 2.3Amps x 0.707 = 1.63Amps .
I don't know how the API conversion factor of .0707 was derived.

Thanks - Dan.
The factor of 0.707 is 1/SQRT(2) and is the scaling factor applied to
peak sinusoidal A.C. current to give the D.C. equivalent current to
supply equal power.
This gives the Root-Mean-Square value. Instanteaneous power being
given by V^2/R necessitates finding the mean of V^2 rather than the
mean of (absolute) V.
I hope that makes sense in your quoted context. I haven't looked at
(found) the source site yet.
For some reason the figure is etched into my head next to the
slightly more trivial fact that the first Boeing 707 took off at 7:07
a.m.
I just found and joined this Group. I will have some dumb questions
as soon as I figure out how to stop the emails coming.
cheers, Don.
