Default Comparison of powers in a rotating domain

Hi everyone,

I have a fairly simple periodic domain. In this domain, some walls correspond to the rotor, and others to the stator. The calculation has good convergence. But according to the results of the calculation, I have a discrepancy in the results for power. I multiply the total enthalpy difference between inlet and outlet by mass flow. And I multiply the moment of the walls of the rotor by the speed of rotation of the domain. I expect to get similar values, but they are completely different.

What could be the problem?
