slip ring motor generator without back emf

Here they are using slip ring rotor induction motor ,i think instead of resistor they are using light bulb as resistor

Why do you think that is a slip ring induction motor?  You can clearly see the diodes that are changing the AC to DC to run the motor.  That looks like a normal DC motor that they have tapped off of to supply power for the lights.  I see nothing to suggest there is no back EMF.

Hi justawatt. I personally am not very knowledgeable about electric motors.

That group is interesting however as they also have a small solid state device which
they claim is over unity, and it appears to be self running in their video demos:

Although a few of them at least appear to be Russian, for some reason they are based in South Korea.


All the best...

Here is a link to a motor very similar to the one in the video.  You will notice it has the connection box on the side and the covers over the brushes just like the one in the video.  The one in the link appears to have a gear reduction unit on the output end but that doesn't change the operation of the motor.

Induction motors work on AC only.  As I posted before there are clearly diodes connected to the input of that motor in the video.  That means the motor has to be running on DC.

Respectfully,
Carroll

PS: I have worked on many motors just like them.

240V shunt wound
1750 rpm, 15 HP
Industrial motor


This motor has brushes, and essentially operates
On two parallel coils.
The commutator makes and breaks parallel circuit
With the primary coil, to provide motive force
By the interaction of the two opposing fields.


The diodes at the switch-box, rectify a/c mains
from the line in (green digital watt meter)
into DC voltage to power the motor.
Can’t really see, but it looks like the power strip
is also in parallel to the coils.


Because of the inductive drain through the inverter
(simplified inverter)
There is a power-factor involved.
With a solid dc source, you would see current spikes
on a scope, every time the commutator switches.


the a/c requires waveform analysis and pfc
to determine the ‘actual load’.
The new “smart meters” can actually detect this and if
the meter thinks too much power is inductive ghost-power
it will automatically correct the reading on the meter.

I've seen that infinitsav device before.  I recognize two of the circuit boards in the box.  One is a DC-DC standard boost converter.  The other is a DC-AC inverter that boosts low voltage DC to high voltage AC.   The bottom board though appears to be their own design and I assume from the video that shows it alone that is where the magic happens.  Interesting circuit if it's real.   Unfortunately they don't seem to be selling them yet and are looking for investors  :(
