The Squirrel Cage Motor, is a bushless motor.  So, ask yourself, where
does the rotor aquire any kind of magnetic field to move?  It's the
secondary of a transformer in a rotating magnetic field, to put
simply.  The current is induced on the rotor which is a shorted
secondary.

Guy,
And here is the very core of your misunderstanding.  A
shorted secondary does not increase the flux passing through
its core.  It resists changes in the flux passing through
its core.  The basic principle is called Lenz's law.  See:http://en.wikipedia.org/wiki/Lenz's_law
Especially note the definition.

If the magnet were a coil with a AC current flowing through it this
would happen:

The shorts surrounding the iron in the rotor of a squirrel
cage induction motor do not increase the rotor's flux.  They
resist changes in its flux.  That is, they give the rotor a
form of short term memory of the flux pushed through it by
the stator.  Not a permanent magnet, but a fading magnet.


Bull***! This is simple transformer theory, Stator = Primary, Rotor
= Secondary and the induced currents produce a magnetic field that is
in opposition. As a result of the induced currents there is also an
attraction caused in other parts of the rotor. A squirrel cage motor
doesn't make that easy to follow.

Look at the parts:

As the rotating field produced by the stator swirls around
the rotor, some of it passes through the rotor (while being
partially blocked by circulating current in the rotor
shorts) but whatever makes its way through is then

Okay, here you prove that you don't really know what you are talking
about.

by that.

current in those same shorts.  This remembered magnetization
is then reacted against the stator field that has mover on
around the rotor, dragging it along after it.

It actually pushes and pulls on the rotor, and it is all a result of
induced currents in the copper parts of the squirrel cage motor and
currents that magnetize the core. But, it really is working as a
Stator/Primary transformer winding Rotor/Secondary Transformer
winding. The direction of current flow through the squirrel cage is
different in different places as it moves. It don't remember
anything.


 The memory
lasts about as long as the L/R time constant of the rotor,
which is well below a second, for most small motors.

If rotation is not involved, and you are dealing with a
stationary transformer, shorting the secondary reduces the
magnetization of the core by the amount that the primary and
supply drop voltage by their resistance.

No, the transformer is a solid block of metal for all intensive
purposes, it can't because there is no structural way that it could.
Even a DC magnet can produce massive changes in the internal core
pressure of the magnetic core.

This would not work if what I just wrote wasn't true:

Essentially all the amp turns produced by the secondary
short are canceled by oppositely directed amp turns produced
by increased primary current.

Open circuit, no current flow, no magnetic fields. Short Circuit,
high current flow, magnetic fields. AC allows for Series Tuned
circuits to stand in for real short circuits, and if the the inductor
is the primary of a 1:1 there is no detuning only a change in the Q of
the inductor.

 But that higher primary
current consumes some of the supply voltage in the primary
winding's resistance, so the effective voltage per turn goes
down and thus, so does the magnetization swing of the core
(which is proportional to the volts per turn).

You have gotten this fact backwards.  And so, your free
energy concept falls on its ass.  A resonant short across a

No, this is where you fall your ass, 1:1 isolation transfomer, series
resonant circuit constructed of the primary winding. Acts like a
short at AC Frequency of Power Source when open on the secondary, Q
drops still acts like short when secondary is shorted. Should have
read the schematic.

secondary does not increase the flux swing in the core, but
decreases it.  Sorry to be the one to rain on your parade.
