Okay guys,

Is there still a phone system in Canada? If so, how about one of you being man enough to call and hash this out, or do you want to leave this impression?

Regards, Larry

Looks like someone turned off the HV coil in this thread...hehe get it??? GET IT?? Cause HV coil gives happy faces....


I'm such a loser.

Yep, it was rather eloquent. LOL"

"What is torque?

It's a measure of the forces that cause an object to rotate. Reaction torque is the force acting on the object that's not free to rotate. An example is a screwdriver applying torque to a rusted screw.

With rotational torque, the object is free to rotate. Examples include industrial motor drives and gear reducers.

Torque and RPM determine horsepower, and horsepower determines system efficiencies".

Yes, we are on the same page.

The most foolproof method is, as they say, done with torque sensors. This is not to say it can't be
done using watts. But accurate measurement in AC is somewhat problematic with leading lagging
phase angles (power factor) and such. The most accurate then is where both sides of the equation
are preformed in DC.

So it is output (counting output heat...but input heat stays on the input side) over input = efficiency, agreed?

That is for overall efficiencies... but nothing says you can't break the system down further and talk
about different coil efficiencies... as long as you put in the disclaimer that this is not system
efficiencies...only individual part efficiencies. Then when doing comparison efficiencies one must
stick with comparing apples to apples and not apples to fig trees, lol
