Can you say: "Tongue in cheek?"
It's clear to me that if the motor load is resistive and draws 6 amperes
from 115VRMS mains, then the power delivered to a nonreactive mechanical
load cannot be greater than:
P = IE = 6A * 115V = 690 watts.
As a matter of fact, (so far) the three basic laws of thermodynamics
1. You can't win.
2. You can't break even
3. You can't get out of the game
So, for 690 watts taken from a source, what will be delivered to the
eventual load will depend on the price exacted by the delivery system.
to form a power
True, but still utter nonsense since we draw power from a voltage source
which _is_ fixed at 120V.
That means that no matter how much power we ask the source to deliver,
it will deliver it into a load which is designed to drop 120V at its
Sure, if the 12VDC source can supply 50 amperes into the load without
sagging, but so what?
I think what's been confirmed is that you're an idiot and, consequently,
that your opinions are irrelevant.

Sonny, there is NO SUCH THING as a pure Resistive for a Motor.......

Even if its inductance is tuned out?

Yes, there is.
A rail gun is a linear motor, and there is ZERO inductance involved.
Mag lev is resistive as well, since it is a DC field on the levitation
There are other examples. Piezo comes to mind.
Sonny? Jeez, ya retarded fuck, get a clue.

All electric motors whether linear or rotating have an associated
magnetic field an hence are inductors.
A rail gun is inductive, hugely so. There is a single turn coil
(formed by the two rails and the projectile) and tens of thousands of
amps. It's only the magnetic field makes it work.
A linear motor is just an induction motor "cut" axially and laid out
Mag Lev is not a motor. No work is done. (Apart from the initial lift)
Neither is piezo a motor. And even a piezo electric crystal has
