one quick question while I'm thinking about it, I have a few charts that try to represent this math. they seem to range from somewhat close to pretty dang off from the actuall math, which is why I'm here in the first place... there is one commonality between them though. as the motor rpm...

yea, all of these numbers are just nameplate numbers. Ill bring my amp meter on monday and see what they really draw. I haven't really cared to conferm that until now. Its one thing to be off by 5 amps or so due to voltage variations and whatnot, but that's a serious difference... hey...

ah, that's true... I forgot about the heat loss. an odd thing that I just looked at, was that I have a 60 horsepower motor that draws 46 amps at 480 as well... that must be a much better motor? based on the horsepower conversion number it would be 51.2 horsepower. It seems like...

Thanks, that was incredibly helpful. That was the amprage and pf number on the motor name plate, perhaps I should go mesure the actual amperage and use that for the calculations?

Hello everyone, Thanks in advance for any wisdom you can offer regarding this matter, I just joined physicsforums.com and am now wondering why I haven't been a member all along... My crudentials: I'm an electrician that went part way through college for electrical engineering, however Its...
