I have a motor I wish to evaluate.(adsbygoogle = window.adsbygoogle || []).push({});

I wish to measure the Joules input and output.

I believe I am making several errors.

Right now I measure the voltage and amperage, calculate watts, and assume that for every second this wattage stays the same. So V*A*seconds = Joules input

To calculate heat output in Joules I use current squared times resistance.

Another energy output is RKE, rotational kinetic energy. I measure RPM, convert to radians per second, determine moment of inertia of the rotating mass, and then use:

RKE = 1/2 * MOI * rps^2

Again, units are Joules.

This is a start. But are there errors above?
