    Bro, I give up.

    This clearly shows why measuring torque and rpm is the only real way to go.
    I am sure your observations for the science lab are well recognized. However even a non electrical guy who does his own cement should be able to follow the experiment thus you hearing the common sense being poured all over your posts.

    You are classical.Totally inside the box. Power factor and high accuracy devices designed only to measure THOSE motor will come in handy somewhere I guess.

    If I put into a drive motor 50 watts and the generator section gives me 1 million watts output you would still repeat all of the same slogans. Now do you get it? Can't you see with a 5X COP that there is no way to wiggle out quoting more book smarts? Oh sure I sound bad, don't I? Just such a bad man huh? Your breaking me up.

    You need to build one that swings a few magnets around, hang a regular coil and then wind a real coil. Then you will think those statements thru a little better. How about 30X cop? Can you instruments cover for you when we all go public with the truth? Or with your hand over your mouth will you cry foul with the evidence staring you right in the face? I think we all know the answer to that one.

    I made a mistake, total input would be 270 plus 240 which is 510 watts. We could say the input from the motor could be halved which would give 135 plus 240 which is 300/375 which is 80% which would be a useful generator.

    By the way, I have another light board just like this that I used to do all my original measurements. I just gave it to Greyland when I left the big machine at his shop. So it isn’t like I will “suddenly” be putting meters on the machine to measure things.

    When you look at the extra input vs output it is pretty good. For the bifilar it works out at 10/8 which is 125%.
    For the ordinary coil it's 10/11 which is 90%. So if you had 30 bifilar coils you'd get 300 watts out for 240 watts
    in plus the 270 iding which is total input 410 watts. 300/410 which is 73% overall efficiency.

    How are you comparing efficiency? Efficiency kind of implies conversion or change. Are you comparing what goes into the motor to what comes out of the coil to establish “efficiency”? If so, I like where you are going.

    I've been thinking about the debunked video. The fellow gets exactly the same .035 efficiency from the bifilar coil and the mono coil.
    There is an effect which can come in to play, see link

    My Prius is a motor generator. The other day I was sure it was going to throw a rod out the side.
    Go to 8 min on this video and hear the racket.

    I had a look at this today. Very interesting.

    Good prototype, looks very solid and well done

    I've just seen your previous message and I see your point about the magic 5. I'm just trying to describe what my own experience has shown me.

    Turion, You've got a decent amount of money but you don't waste it do you? Well, treat your motor generator the same way, best practice will pay off in the long run.
    My main interest has been in small wind projects where axial flux is appropriate in so far as you get high efficiency at moderate speed. For me an efficiency of somewhere in the mid 70's isn't too shabby so what you're talking about is in a whole different ball park!

    Quantum,
    I’m paying attention. The main reason I wanted a better working prototype was as a test bed for many of these things. Speed can also take me right past the “neutral zone” on my coils and you should see the motor take a five when THAT happens.
