Tesla's Charging Circuit and it's Application to Pulse Motors

Umm

E = (Iw2)/2. So where I = 0.00098655969 and
where w = 230.2666 then E = 26.155 @ 2200 rpm

Where w = 157 then E = 12.1588 @ 1500 rpm

And where w =  104.6666 then E = 5.4039 @ 1000 rpm

Need more data now.

MileHigh, It looks like your method is spot on or very close to the calculation method.

For your method I get the figure   I = 0.00098655969
And by calculation I get the figure I = 0.00091038461

And when I measured and calculated I did make a compromise because of the shape of the squirrel cages ect. Still very close and I'm inclined to go with your methods result because of the calculation compromises would increase the calculated figure, and the consistency of the results I got from your method.. Awesome stuff.

Now to put it back together and run some timed run down tests that should give me meaningful results. Oh but first I'll do some more drop tests to confirm the result better, I've got more weights and whatnot.

Farmhand,

I am glad that you are having fun.  As a reminder, anything that you can do to reduce the friction and/or cogging that results in a faster RPM after the weight falls is going to reduce your calculated moment of inertia.  That's a good thing and should give you more accurate results.  As long as it's passive and does not add any active power or energy to the spinning rotor you are fine.

About your first round of results:

For your method I get the figure   I = 0.00098655969
And by calculation I get the figure I = 0.00091038461

Note that these results are "satisfying" in the sense that the dropping-weight method shows a larger MOI, and we can suspect that unwanted friction might be the main cause of the higher MOI measurement.  So it's reasonable and could be expected that the dropping-weight MOI measurement should be larger than the other method.  If it was the other way around and the dropping-weight MOI was smaller, then the first round of measurements would not "smell right" which would merit further investigation.

I happy to have the fun. I'am also happy to have been able to demonstrate your idea for the drop method to determine the MoI, and that it worked for me, I hope in some small way that it might help make up for my previous emotional outburst towards you  , it was uncalled for and I apologize. I did feel as though I was being deliberately dismissed and "misunderstood", "just how I felt" but I hope that can be water under the bridge as my misunderstanding of the situation.

I'm having a relapse of my neck problem so i'm struggling to focus at the moment in both ways my eyes and my mind.

I am having difficulty to get an accurate measure of the rpm during a run down event between two rpm points like 2500 rpm to 2200 rpm, the tachometer jumps too many numbers at once.

I'm thinking it might be time to work on the control circuit and maybe change over to the hall sensors and the Arduino, I've got the halls but they are tiny small, the Arduino I kind of could not decide what I wanted to get. I think I'll go with the one Tinsel recommended, The thing I like about the picaxe system is the small chips like the 08M2 and 014M2 chips which can run a circuit or part of a circuit by programming the chip then inserting it in the circuit. Or they can use the USB to audio socket on the board to program in circuit. For simple or moderately complex tasks that I can program for they work well.

If I get the Arduino and set it up properly I should be able to use that to read the RPM/frequency accurately, my issue is I lack the programming skills to do anything with the picaxe except what I can learn from the PDF manual or work out using logic, so my code is simple and primitive, till I learn more.. But the picaxe is still very useful even for people who can't write code for bananas. Very useful controllers.

Farmhand,

Apology accepted and it's water under the bridge.  I am not perfect and have done a few outbursts myself.  Just for your knowledge, my real interest these days is to debate the "professional" free energy propositions.  So I debated with John Rohner of Inteligentry infamy on PESN as an example.  I could tell that he was full of crap, and was basically a criminal.  Other contribtors on PESN like Mark E. could see through him just like me.   (If you want to observe someone that really knows his stuff in "action," try reading Mark E. on PESN.  The guy is brilliant.)  About thee months ago the FBI did a raid on Inteligentry for fraudulent solicitation for the selling of shares in his company in violation of US Securities and Exchange Commission rules.  The FBI report also mentioned that he was making false claims about his alleged "PAPP engine."

So that was fun and I got a kick out of that.  I view that as doing some good for the community at large.  These types of "professional" free energy propositions get some coverage on OU from time to time and sometimes the real players will post here.  It's fun to get into a debate with the actual people that are in a high-profile professional looking proposition.  Sometimes I can spot a fake quite quickly because it becomes apparent that they are bluffing and don't know what they are talking about.  This is especially true when talking about electronics because of my background.  It's important to state that I am no genius in electronics by any means.  I was never a big analog electronics fan.  However, for most of the analog electronics discussions you see around here I can pretty much grasp what is going on.  I am not qualified at all to do serious "real" analog design work.

As another high-profile example, on the "Delayed Lenz" thread I looked up Magnacoaster and just discovered that the web site was revamped into a medical quackery web site.  Richard Willis of Magnacoaster is another person that is a fraud.  To bad he didn't dare come here himself to drum up business, because myself and others would have justifiably made mincemeat out of him.  I can tell that he is bluffing when he talks about his electronics circuits.  The Magnacoaster systems have apparently vanished and now he is Doctor Quacko and his Magnetic Belts Inc.

With respect to the goings on here OU, I tend to get lightly involved in the occasional thread for fun.  I don't get deeply involved simply because I have read and commented on many threads in the past so the novelty wore off a long time ago.  So I am glad you are having fun and learning as you go along.  I hope that your neck problem goes away or is at least bearable when it gets bad.  I have had two back operations from a crushed disk and I know how bad it is when there are problems with your nerve system.

I wrote assembler language programs for the 8088 and the 6502 back in the day.  I know nowadays that you program microcontrollers with a high-level language.  There is a kind of "nerd thrill" when you write in assembler because you have full control and have "taken over."  Assembler also runs blazingly fast.

So carry on and have fun!

For even more fun, you might want to look up "The CMOS Cookbook" by Don Lancaster.  That book excited and spawned a whole generation of electronics hobbyists way back when.  You can probably say that it's part of the "Nerd Collective Unconscious."  lol
