If the field supply fails, how is there any torque to spin the motor faster?
I'd have to assume that the ever stronger armature current probably
maintains a weak
residual magnetic force in the field iron. Brush positioning etc would
likely prevent
its ever going to a true zero magnetically.
I first recall reading about it in the high school physics textbooks
used in the Iowa
schools circa 1941-2 that my mother brought home from the county
library. I had asked
her hat gravity was, not understanding that now, in 2022, we still don't
know for sure
what it is.
We can measure everything to quite a few decimal places, but we still do
not know its
propagation velocity. The puzzle stems from the fact that in order for
the orbital
mechanics math to work as observed and as Katherine Johnson used to put
our guys on the
moon and bring them home again, has to assume its not C speed limited.
If it was, our
home planet would have spiraled into the sun billions of years ago. The
data we get from
the scientists/astronomers, says it is C limited, because the 7
neutrinos we captured from
SN1987, got here within milliseconds of ligo registering the event. And
we've had similar
correlations in the years since. But that speed limit of C, messes with
our orbital math.
So one of them is wrong. We've been arguing about it for about a century
now.
The difference in its vector, created by the suns 700 mph motion thru
our neighborhoods
space, must be from where the sun is this instant, not where it WAS 8
minutes ago when its
light left there. It is not where WE see it when that light actually
gets here 8 minutes
later.
Military SOP's change rather glacially, so I expect shipboard SOP
manuals still mandate
fuses or circuit breakers in series with the armatures of any motors so
controlled.
