Jon,

Being sure and being right are NOT the same thing!

As an example, Literally hundreds of music books state that
Stradivarius made the BEST violins... Yet in nearly all 'double
blind' tests, the 'Strads' are NOT the winners! Even more intersting
is that when the 'test' is run without 'blinders' (let's keep the
horses involved here :-) ) , the Stradivarius AGAIN is selected BEST!

That 746 Watts EQUALS one horsepower is not an issue. It DOES, by
declaration and acceptance as an intenational standard. What I am
arguing, is the discrepancy between THIS standard and the 550
in.lbs./second horsepower standard. We have been engaging in some
circular logic, where the assumptions are considered correct, and
then used to 'logically' arrive at the desired result.

My assertion remains that the "electrical horsepower" does not seem
to correlate to the "mechanical horsepower". In my last post, I did
not have the info re: torque of the motors involved, and derived it
from the mech. equation. Then I ASSUMED the motors were labeled
correctly by the mfr's. If the torque values are way off 'reality',
then the assertions made are incorrect. It seems reasonable to me to
believe that the leeson motor torque will be about 14.5 times
(4.567/.315) the router. The speeds are also 14.5 times apart
25000/1725).

How do those of you in the "Watts in = HP out" 'camp' account for the
increased torque ratings of stepper motors through the use of better
magnets?
Give me an old superior 23 single stack motor, and a new pacific-
scientific 23 single stack motor , each with the same Volt/amp ratings
(and therefore the same wattage)and I am confident the newer motor
will have "more horsepower". Meaning that for a GIVEN INPUT IN WATTS,
IT WILL PRODUCE MORE OUTPUT IN TORQUE AT SPEED than the older motor!
Has to be. The magnets ARE better! Watts are the same.

What say ye all?
