sure: by DEFININITION,
HP = (Torque x RPM)/5252
hp = horsepower
torque is in ft/lb
and RPM is revs/min.
without 2 you can NOT figure out the third.
stall torque is not the same as continuous torque nor is it same a "max torque".
Ok max but at "max what"?
RPM, max current w/o demag, max continuous current, max light of the moon, max what???
Unless you have the torque vs rpm curve, your guess is as good as ANY as to what the third is or wher it was rated.
By the way, unless you know the power factor
1 mechanical HP is NOT 100% equal to 745.7 watts if power factor is only 80%
Be careful of the numbers game and "game" is being charitable when it comes to rating game.
