Embarrassment time, dyslexia strikes again. The impressive second reading is an error on my part.

Correction for post #678

The millivolt numbers are correct in my notes, 11.6 mV under load and 10.3 mV no load. I was just dividing by two to get the amps and a very simple mistake occurred on the 11.6... I had written down 5.5 instead of 5.8 and subtracted 5.15 from it. What a difference that makes... from 8.575 watts to 16.25 watts! Sorry about that.


So corrected, the number two reading is 14.28 Watts out for a cost of 16,25 watts in


The best reading today is at 2800 RPM, 12.03 watts out for a cost of 12.5 watts in


The RV draw numbers are correct


Ron



Hey Ron, no problem, it happens.

Too much Coffee maybe?

P.S: Due to lack of interest, I am currently seeing no point doing the Build Off Challange - Seems that we have seen soo much talk, but as always see no Action - Whats going on?

Nah, just short term memory is very very short term, LOL ...that and every now and then I transpose numbers.

Chris, to be more specific, the drag increases up to a certain point, then there is a dip, followed by a resumption of the increase.


This is with no electrical load being drawn, so it is not Lenz related. It must then be strictly a magnetic phenomenon.


Ron

Quote: By Lenz's law, an eddy current creates a magnetic field that opposes the magnetic field that created it, and thus eddy currents react back on the source of the magnetic field. For example, a nearby conductive surface will exert a drag force on a moving magnet that opposes its motion, due to eddy currents induced in the surface by the moving magnetic field. This effect is employed in eddy current brakes which are used to stop rotating power tools quickly when they are turned off. The current flowing through the resistance of the conductor also dissipates energy as heat in the material. Thus eddy currents are a cause of energy loss in alternating current (AC) inductors, transformers, electric motors and generators, and other AC machinery, requiring special construction such as laminated magnetic cores or ferrite cores to minimize them. Eddy currents are also used to heat objects in induction heating furnaces and equipment, and to detect cracks and flaws in metal parts using eddy-current testing instruments.

Ron
Here is something you might like to try to see if the drag without load is lenz related.
Is it possible to replace the magnets with small steel pieces/or one steel rod,that are the same shape and size as the magnet's,and then run the DUT,and see if the same amount of load/drag is placed on the prime mover as if there were magnets in the rotor?.

I see you mentioned that you did the temperature test,and the results were opposite to what i thought they would be--and this is interesting  ???
Perhaps i should put aside my solenoid engine build for a while,and finish my setup like yours,and join in on the search for the !hidden! drag ,when no load is being drawn from the generator.

@ Ron

So i have just been watching some of the video's on your channel,during my morning coffee--and wow.
You have some excellent builds on there Ron,and craftsmanship i have only seen once before by another.

A video from a channel you might enjoy,by a man that shares your skills.

Thanks Brad,


Yes, he is good, I haven't followed his work as much as I have Luc's, but they both suffer from the same malady, videos that are too long.

I think we should have been warned when Ward was shown diving his models with one and two horse motors. That and we ignored the fading of the Butch team. Still. as Chris says, it is a good learning tool.


And holy moly --- it actually got the group focused on a, "lenz free generator", for several pages!


And some good laughs... such as the one posted by ramset  ;D


What one shall we do next?

Hey Ron - I agree, you’re the only one here that has held the attention of others for more than one page - Congratulations!

Yes, I agree, did I say: "Not OU but a good learning tool"? Something like that. I really do agree, there is a lot to learn in such a small simple and cheap device.

Maybe I might be able to help the thread with some of my work? Please read my Warning!!!

Please See: Chris's Build Entry

I am a Nube when it comes to motors, I know basic stuff and thats really it!!! I am here to learn some and for fun only.

I have some progress posted. More pictures than words.

Seriously, is this the best you have to offer, a copy paste of Brad's work?  Why in the hell is this a "Brad Challenge"?  "The challenge" was between Brad and AC. You have extended the challenge to everyone.....not wise.  It's clear you ignored my suggestion, namely to present one's best (ignored by Brad...) motor generator concept.  This is non threatening, and has nothing to do with a competition, this is us placing our cards face up on the table, this is us seeing one another, revealing where we are, why we are there, and where we are headed.  I find it fascinating that you speak with such authority, and all of a sudden you are a "noob"......typical.......  Present your own idea about your own approach to a motor-generator. Demonstrate that you are not only well versed in the laws, but you also know  how to apply them practically. 


It's good of you to admit that you are a noob....says a lot about you, and I respect this.  I am not a noob in the area of motor-generators.  This discussion belongs here on this forum, I recommend you start a new thread, you could call it, "Your BEST motor-generator concept".  It should be modeled after the opening video of the pulse motor build off. Participants submit a 5 minute video, posting the link to the video in the thread, that's it.  What you do with your 5 minutes is on you, at the end of the time period, it is my hope that all understand why this is your best.  The submission thread is for entry videos only, no discussions should take place there ever! 


If a discussion is desired about a particular idea, the individual responsible for presenting said idea should start a thread, and be given total moderator control, modeled after the bench concept on the OUR forum.  No one has the right to start a discussion about someone else's idea.  There should be no time limit on submissions, this is not a competition.  Only one submission per user, remember this is about you presenting your best. 



After a skim read, I wasnt going to respond to your post, so I shall Not ;)

Hi Ron , I didn't pay much attention to your ward generator, I 'm on limited data.

What one shall we do next?


Ron
The reason is, I don't like cores in my coils.
It's fine to use steel to concentrate the magnetic field of a PM rotor but, using it to intensify the field in a coil is a waste IMHO.
The reason I say this is ,from what I've seen is that increase in output is offset by the required increase in input or the increase in motoring ability is offset by the drag .
Something along the lines of core-less coils for motoring and generating at the same time,would be interesting.
Thanks artv

Under permanent energy load or under moderated pulse periods ?
rotor/stator: pm/pm pm/em em/pm em-pm/pm ...em-pm/em-pm  magnetic force source : pm=permanent magnet em=electromagnet

 You think that air-core coils equipped machines does have a better effficiency ,caused by actio-reactio time ,or why ?
Is the field force intensifying solid core reacting as same when instead cooper coils this will be encored by cooper-alu or only aluminium coils ? Aluminium: eddy currents ! Non ferrit machine,but by magnetic force acting ? http://rexresearch.com/mrmagnet/mrmagnet.htm

A really ashamed  :-[  question,could you descript for me the programming of this "operation=act" ? I only know about "winding coils" !

Are you revoluting your motor by hand,handykraft,mechanical device,not an e-motor more a kinetical/mechanical transmissor /transmitter ?
Thank you for a more imaginable answer ! :)


With my kindest regard and a fine Sunday (with/-out family,in peace ::) )

That is exactly what one should have!
