Delayed Lenz or not?... post your explaination!

[MarkE]

Put the efficiency to a 100% if you want ... you still cannot beat the above

BTW, just noticed that post put you at exactly 4000 posts... maybe this is a sign of some kind

If I could find a 100% efficient machine such as some kind of motor or generator that would be a little bit better than the high 90% range that actually exist.  It's the vertical wall at 100% that seems insurmountable.

                we all know the rules, my question is: How can we delay something
that MUST have happened?

Luc:

I wasn't suggesting to use this little 60 Watt dremel motor as a prime mover for a larger 100 Watts version. I'm not that stupid!  (http://overunity.com/Smileys/default/rolleyes.gif) give me a little more credit.
I would appreciate you answering my question and not brush it off with "Your power analysis is completely wrong"

I simply did not understand your prose.  In both of your explanations you don't mention the requirement for the prime mover to supply more mechanical power.  The burden is on you to express yourself properly if you want people to understand you.  What you seem to be saying is that a more efficient generator configuration in terms of electrical power out vs. mechanical power in is a good thing.  Who can argue with that?

From your YouTube clip, quoting you:

No drag on the dremel. If there was you would see the Frequency reduce (= less RPM)
I can pull 3 Watts out of this miniature coil and magnet if I increase the Resistance with no drag on the dremel.

There is drag on the Dremel.  Again, the Dremel is acting like a conventional motor so the added Lenz drag of the generator coil load will only marginally reduce the speed of the Dremel while the electrical power draw of the Dremel will noticeably increase.

You second sentence is baffling.  Why do you say there will be no drag on the Dremel?  If you pull three watts from the generator coil there definitely will be drag on the Dremel.

Going back to the testing, there is no "delayed Lenz effect."

Hi everyone,

I'm starting this topic to further study the effects of a generator coil which causes no load to its prime mover once connected to a 1 Ohm resistive load.
It seems we have many views about what could be happening in such a coil and maybe together we can find an explanation we can all agree upon.

I made a video of a simple test device that demonstrates a coil I consider having this quality.
A sense coil has been carefully positioned in order for both coil sinewaves to be in phase which can also serves as a rotor magnet timing reference.
During the video I didn't verbally explain because of the prime mover noise. However, it should be clear to most who have experience on the matter that once the coil is placed under the 1 Ohm load there is next to no change in Frequency (motor RPM). What's also clear is there's a delay in phase once I adjust the scope probe voltage division.

So the question is, what causes current to delay in a resistive load and what is going on in the coil to cause such an effect?

First step would be to show that the generator coil/core does not cause any load even without the resistor.

1) Run the prime mover with no coil or anything near the rotor and determine the real input power from the supply, = Value 1.

2) Then run the prime mover with the coil/core in place ready to load with the load resistor, but with no load and also determine
the real input power from the supply, = Value 2. If there is more input power used in step 2 then there is already a "parasitic"
load on the prime mover from the coil/core. Lenz depending on the coil/core properties the open circuit "Build in Lenz drag" can
made to be a lot so that there is ample parasitic drag to relieve with the load or it could be a little.

3) Then run the setup with a load in place and determine the real input power from the supply and the real output power, if the
load resistor dissipates power of a value greater than the value of the difference between "Value 1"and Value 2" and the input
power in step 3 is the same as the input power in step 1 or less then there might be something of interest.

My guess is that there will be an increase in input power in step 2 compared to step 1 = (increased Lenz), then when the load
is applied so as to not increase the input further still from the input power at step 2, then the output will be a result of reduced
losses, or converting the increased losses (as evidenced by the increased input at step 2 compared to step 1) into an output.

It's almost the old "problem - reaction - solution" paradigm.

..

The answer to your question is in the MIT lecture on "inductance", I've linked the lecture a few times in threads relating to this effect.

It's a restriction of current due to frequency to high for inductance along with some other factors all well explained by conventional
theory and fitting into an under unity reality.
