  • Phase Shifted Induction

    Hi all, i just finished building a new incandescent light bulb heater and i was pondering building an improved heater, something going above a C.O.P. of 1.
    I remember reading this PDF awhile ago, though i have yet to act on it.
    Eddy Current Heaters
    So i plan to build a small test model, using one of my small DC powered, brush-less air plane motors.
    I will make a small aluminum disc and rotate this in front of some neo magnets.
    I will use a speed control to find the rpm needed to cause the proper phase shift or delay, which will then nullify the mechanical back torque upon the prime mover motor.
    I have already verified this can work.
    I used my TV ferrite flyback c-core, which i was using with the sucahyo pulse drive circuit.
    I then placed part of a thick piece of aluminum heat sink material in between the gap of the c-core.
    I started at a low frequency, which caused a noticeable increase in amperage.
    I then progressively increased the base resistance on the PNP transistor base, which increased frequency, until i was able to observe the amperage stop increasing, when the aluminum was inserted in the ferrite c-core gap.
    With a 100 kohm base resistor, the frequency was barely audible and i observed the amperage decrease from 11.3 milliamps down to 9.5 milliamps, when the aluminum was in between the gap, compared to without and same gap distance.
    Your thoughts about this and the PDF are most welcome.

    I am afraid you will burn out your airplane motor. I also fly electric RC planes. Those motors typically run pretty hot. They depend on the air from the prop for cooling. Unless you only very lightly load your motor I think it will overheat. A motor from an RC car might be a better choice.

    Just because someone disagrees with you does NOT make them your enemy. We can disagree without attacking someone.

      Hi cifta, ok thanks for the information, i do have a couple 600 size rc car motors and brushed speed control, i will use that instead.
      Cifta, so do you think the solid state induction test proves the principle shown in the PDF link i shared and any other thoughts to share.

        Hi all, so for the moment, i am making tests with solid state setups, to get a better feel for this effect.
        I feel the sucahyo pulse drive circuit, is a better option to test this effect also, since it does not rely on a separate feedback coil wire, which could distort the results.
        So i have my partnered bucking coil setup from previous experiments and i am testing it without a core, so air core coils.
        It has a 2 strand coil in center of 24 awg., strands placed in parallel for one coil wire.
        Then on both sides of this center coil, it has 24 awg. coils also.
        Testing with these coils is also showing the same effect, as with the thick piece of aluminum heatsink material.
        At a certain lower frequency, input is 11.9 volts, .81 amps unloaded and with the outside coils in series and shorted, the amperage rises to .87 amps, with a 6 watt led bulb,
        it is .85 amps.
        At a certain higher frequency, input is 11.9 volts, .49 amps unloaded and with outer coils shorted, amperage remains at .49 amps, with a 6 watt led bulb, amperage then decreases to .48 amps.
        At a certain even higher frequency, input is 11.9 volts, .23 amps unloaded and with outer coils shorted, amperage decreases to .21 amps, with a 6 watt led bulb, amperage decreases to .19 amps.
        Interesting results i think.
        Your thoughts are greatly appreciated or any experiments you would like to share, that correlates with these results.

          Nice work sky!
          Have you some picture of your setup?
          Thank you for being a sharing builders!

            Hi wistiti, thanks for the reply and kind words.
            Here is a picture of the setup, the 3 air coil is in front and the previous testing 3 strand coil is in back, with the thick aluminum heatsink material, with the ferrite c-core.
            It is that test that showed the phase shifted or delayed lentz effect at a high enough frequency, and this 3 coil air core setup is showing the same thing, at high enough frequency.

              Phase shifting

              Hi sky ,
              Great work there am much interested in what you have shown . If possible could you show a schematic?
              What you show seems much like the James W. German patent , if you get a chance take a look . Just Google it it will come up . A generator was built and shown on Y tube that claims to work on this principle. Is still there but nothing much is posted about it . Was a gut from Indonesia . I have not built it but would like to know more about your solid state type set up .
              Thanks for sharing and posting .

                Hi j dove, thanks for the kind words and i will share everything i discover about this effect.
                I will also look into that James W. German patent you referenced.
                Also, unless I'm mistaken, this could also be the effect Thane Heins is using in his mechanical generators.
                Thane does show a bi-toroid solid state device, though i think that functions by redirecting the secondary coil flux away from the primary input coil to achieve similar effects.
                So, i think this effect i am seeing, could be the solid state version of Thanes mechanical device.
                Here is the schematic.

                Edit: also, i am specifically using air coils, to avoid the ferromagnetic core losses, that some could claim as being the cause of the effect.
                With air coils or solid sheets of copper or aluminum, those losses do not exist.

                  Hi all, i made an experiment based on the pdf i linked.
                  I used a wall powered dremel tool and made a disc out of aluminum roof flashing, about 3" diameter.
                  I used a killawatt meter to view any increase or decrease in watts.
                  If this dremel is 17000 rpm, then the maximum frequency i could attain, was 283 Hz.
                  I'm not sure that is fast enough to reveal the effect, since i did see the watts increase double when moving disc close to a stack of 1" diameter neo magnets.
                  The pdf says a few hundred Hz, so maybe with this thin aluminum disc, the L/R time constant is too short and it would need a much higher rotation speed.
                  After all, the solid state experiments i made, were using high frequency, for sure above 10 KHz and with a much higher L/R time constant as well.
                  So, i have the feeling a much thicker disc of aluminum or copper would be needed to increase the L/R time constant, to enable a more realistic rpm to be used and of course that means much higher power equipment, which i do not have.
                  Hmm, what about a solid state induction heater, pushed up to a frequency that causes a similar phase shift in a solid plate of aluminum or copper.
                  Your thoughts appreciated.
