Really ???
1. Then please explain how a neutral has full current without any voltage, and has been known to actually kill people who had your train of thought (on this matter)
2. Now you just eliminated eddy currents for everyones enjoyment, if what you stated was true
A shunted coil .......... just like I stated in my previous post
So if he used a non-electronic scale, what would you have to say ?
I love reading your posts, and usually agree with you on most things, but I just about have my PE in electrical engineering. Peace, my friend
I respect that you're going for your PE - I never did. I have spent 26 years designing equipment to measure current, voltage, power, etc on 3-pahse systems. If you believe there can be current flow in a conductor with no potential difference across it then I encourage you to review. There are a few laws that would be violated if that happened. I assure you that if current flows in the neutral, there is a voltage driving it.
I actually have no idea what point you are trying to make - I don't care in the least what method is used to measure torque or rpm or power. Use a spring scale instead of an electronic one - that indirectly measures force by pushing against a spring, and one must then calculate torque using a distance indirectly measured with calibrated marks on a stick.
All such methods will be indirect, and none of it is relevant to the point I was making - that whole thing was just Thomas doing his usual tactic of fishing for a "gotcha" angle so he could claim I'm wrong on some point and that then anything I say is wrong.
Rather than the way things are measured or how to use the equation, the point I was trying to get to was the meaning of the terms. Work is energy, which is power times time. Torque and rpm are just parts of what makes up power, are of equal importance, and in fact through gearing one can be converted into the other. If you want to do more work, you can increase either torque or rpm.
What changes the usefulness of the saw power band is how peaky it is - the shape of the plot of HP vs. rpm.
