motor horse power
Is it possible to determine the Horse Power of a motor by measuring a resistance across the windings??
I know we can calculate volts*amps=kva*power factor =KW of motor input. But how about just testing the windings??

In a word, "No".

I used to work in an electrical rewind shop when I was in the Navy. The power was determined by the number of coild, the number of turns of wire in each winding, the size of the coils, and the voltage applied.
Gibson is essentially correct. you can't determine the information desired without knowing the design of the item.I visit http://www.fuel-saver.org

You can get an idea, but your meter is measuring DC resistance. AC reactance will be between 4 and 6 times that value most of the time. I have seen AC reactance to be 10 times the DC resistance on high torque motors.

I would dearly love to see a table of values developed on that, superheat.
