    Cement man batteries? Go cement man. Fun with cement intermission. 6 weeks to go. pour that cement.

    Cement man I guess he is still doing cement, 4 sale?

    bro,
    You were right! I was doing cement today. I have no clue why adding magnets has that effect. I have never seen that happen. 1BB8C04D-B8C1-4DF7-94B6-4AD4E677A2D8.jpeg

    I need to find the Neo magnets. Sounds like weak magnets. But with double the magnets you double the FREQUENCY. To find the AMOUNT of ENERGY you need to RECTIFY and send to a load.

    Also to find the frequency of operation of your machine is easy.
    Let's say your rotor turns at 2000 rpm's well that is revolutions per MINUTE not seconds. We must reduce that figure to seconds because Hertz is in seconds. So to find revolutions per second of 2000 per minute divide by 60 this = 2000 / 60 = 33 rps or a single magnet traveling in a 360 degree circle going around 33 times. But you have 16 magnets. 33 X 16 = hertz.

    I have asked for years if anyone on these boards can find the frequency in Hertz of any machine. No one has been able to do this as simple as it is. I have posted answers to calculations that were false, no one has corrected me. This shows the level of schooling.

    So what is the answer? Does anyone care? Where is your excitement learning new thing? Is frequency not worth our time to consider? Does it have zero impact and a project? Come on people think.

    I have been banging heads with creatures from the lake on this sites for years who want to dismiss everything I say. Well good luck with that I won't be moved off topic. Look around the web, nobody understands frequency vs power density.

    Because this is more complicated than just plugging in a few values in a computer modelling software nobody can get the answers right. Therefore I must be a false instructor.

    You all think 1000hz like Dave's new machine is the same as Liber63 Hz? Dave's has 22 magnets and he is running 1000 hz, Liber is running who knows what as I do not know his RPM's

    What were voltage values on the no load tests?

    anybody can see my rotor. Multifillar coils, 6 strands, 50 meters each. Tried every possible connections series-parallel between them, as Dave has suggested. The outcome, which means watt of the coil, was always less than half. Say, with 8 magnets was 20 watt, with 16 magnets was 8 watt. All parameters the same, but number of the magnets. Magnets NNN. Come on, people. There must be others who faced the same thing. Maybe they just don't see this thread.

    Yes, I reviewed that post. Are you just using a single coil? And to get watts, do you use a resistor as load? As you'd need both voltage and current. In this case, can you measure no load voltage in both ways? That would be telling.

    For the coil, each rotor magnet passage represents one cycle of generated voltage. Imagine a sinewave cycle. The strength (flux) and the speed (RPM) of the magnet determines the height of the waveform thereby the rms voltage according to Faraday's Law. The RPM also dictates the frequency, number of cycles per second. Doubling the number of magnets will double the frequency but, at first glance, should not affect the height of the waveform cycles (rms voltage). Doubling the frequency will affect the impedance (increase for inductive circuits).

    Another telling test would be to look at no load voltage from a single strand coil both ways and see if it is the same. If it goes lower, like by half, then I think it safe to say that the issue is with flux reduction. It could be that fully populating the rotor has altered the magnets' flux paths where much less flux links or cuts the coil.

    I continue tests with my rotor and coils and lately I changed my rotor from 8 magnets to 16. Same dimensions for rotor, same coils, same core, only more magnets. Output has fallen to less than half. Does anybody know why? I expected to be quite the opposite. It took me by surprise!! I also tried with the half of the length of the coil, but same results. I think I should try with half of the length of the core as well. Does anybody have any suggestions?

    Hi liber63,

    That's interesting. By output, do you mean coil voltage? Also, please give some additional details. Are magnets arranged NSNS... or NNN...? Bifilar coils or std? RPM? Inductance? Photos can help.

    Regards,
    bi

    My house goes on the market this coming Friday. Until then I have no time for this stuff. Too many little things that need to be taken care of as that day approaches. I have accumulated permalloy core material, nanocrystaline core material, several kinds of iron powder core material, black sand, ferrite, and a couple others. Each one will be tested, with my old standby iron core as a baseline. I want to know output, RPM for the neutral zone, as well as upper limit before “speed up” and reduced output occurs. As soon as I get all the data from the standard core that is currently in the machine, I will even do some of the testing bi has been so eager for me to do before I put a different coil in place. Namely inserting 10 cores and measuring what happens before and after magnetic neutralization is implemented. The new motor with the more secure shaft adaptor has already been mounted. Once I have determined what core is best, those are the cores I will base future claims on, and that will be an accurate assessment of the potential of this machine. While the current cores do exactly as I have stated, the heat issue limits the run time of the machine. That is its limitation, and it is currently a BIG one. I am fully aware that the output of the machine is likely to go down with these new materials, but input probably will go down a bit too. I have no idea what the ratio will be.
