Table 1. Comparison of maximum open loop speed
and optical speed.
this case we can see that the optical speeds remain close to the optimal open
loop results. There appears to be a bit more variation in the speed differences
in this case. The reason for this is unknown.
current, voltage and power curves are shown in fig 1.

peak current demand is now 100A and the corresponding peak source internal loss
has reached about 800W.
