In article , Don Foreman says...

No, he didn't, but he did put a *heavy* flywheel on it, and noted no
improvement. In fact, the converter can't respond as quickly to changes
in load with a heavy flywheel attached. (And we want it to, since the
majority of the energy in, and all of it that is passing through, the
system is electrical, not mechanical.) [gary]

OK with the first sentence. Did he observe and report what you
assert in the second sentence? You note that he noted no
improvement. Did he note any degradation?

I think the experiment of interest would be to somehow
create a rotor with a much lighter than normal mass, and
see how *that* behaves.

It is pretty apparent that the ratio of energies is what's
being discussed the the kinetic energy of the rotor vs
some other energy stored in a magnetic sense. Possible the
moment of the squirrel cage field in the applied field of
the excited stator winding. That's won't be exactly right
but it would give an upper bound on the stored magnetic
energy.
