    I posted this in the other thread but meant to post it here...

    Thought this would be a good time to mention this, from Bill Muller's website. It's about timing the circuitry of your generator coils.

    The rotor is turned by a motor, such as a diesel engine or a windmill. As the rotor magnets revolve past the coils, the magnetic field induces a pulsating electrical current which can be used for any purpose. However, first the generated electricity must flow through a solid state switching circuit (which is not shown).

    The switching circuit turns the stator coils "on" and "off" at the appropriate times to "clip" and channel the current flow. This prevents the buildup of forces which "buck" (back emf) the generator and reduces its output. This switching circuit gives the Muller Dynamo virtually zero rotor drag and virtually all of the motive force is turned directly into usable electrical energy.

    Rod, I would love if you sent me that program you wrote... relating to the driving coil. How do you want me to get you my e-mail?

    I agree Ferrite never worked well for me. the best result was MU metal. I wish that stuff was no so difficult to get and work with.

    the core I am testing at the moment is a solid peace of mild steel.
    it get very hot
    But it works in other ways as opposed to laminated cores.

    Looking back at other post on this thread and there have been a range of
    explanation presented.

    you need to now find a way to make improvements to get past 3000 RPM.
    look at you core materials. What is your core made from?
    good work

    As i continue experimenting with my rotor i found this strange phenomenon that i will try to describe.

    The rotor spins freelly around 3000rpm

    I connect a load (12V light bulb) and the rpm goes down around 1800rpm

    Then, with the load connected i short the gen coil ( light bulb turns off ) and the rpm goes up around 2600.

    This phenomenon happens only around 1500-2500 rpm and only with the load connected. I didn't use any capacitors like before;just the coil the light bulb and a simple cable to short the coil.
    Does anyone have any ideea what is going on here??

    A question on the "motor" coil ?

    ToranaRod
    One of our very dedicated Open source engineers at OU dot Com
    Is having trouble posting to this thread
    He asks The following question

    Teslalset
    Quote,
    For some reason I can't post messages on EF although I have a valid account.
    Can somebody post a question to Toranarod to provide also the input power of the motor coil, to complete his table?
    ------------------------
    Question from Here

    Confirming the Delayed Lenz Effect

    Thank you

    Hi Elias,

    I apologize for coming but the diode bridge with the 4 diodes is a must for Rod if he uses a single MOSFET for coil shorting, had he not used the bridge then the single MOSFET's body diode across the drain and source electrodes would short out every second half wave which would be forward bias for it. The diode bridge isolates the AC output of the gen coil from the single MOSFET, this way the body diode can never sense forward bias voltage but a reverse one between its drain and source.
    So whenever the FET is ON, two diodes from the bridge 'clamps' the AC output via the drain-source ON resistance, this is why there is 1.8V (twice the forward drop) remaining across the coil.

    Unless he uses the two Mosfets after the diodes. One for the upper half, and one for the lower half. I have also found out that the drag when the magnet approaches the coil is lower.

    Thanks for the news Rod and Slider! Keep on keeping on, it's coming.

    Question for Rod, what cores did you end up putting in your Muller?

    you are right. Just one interesting point the Muller configuration works very differently to the standard Bedini rotor setup. Even if the magnets and coils are the same it behave completely different. At the moment I cannot account for this.
    I am assuming you said the magnet strength and coil inductance/resistance is the same. I'm thinking the magnet spacing and magnet speed passing the coil maybe different. If the rotor size the the same, then the bedini setup would have higher magnet passing speed because it positioned at a higher radius. The RUK setup seems to have a closer magnets spacing. One other thing I may see is the field strength and flux maybe involved.

    It's like when you have a garden hose shooting water through a loop. You can change the flux in the loop in two ways; Keep the hose still and increase/decrease water velocity or keep the velocity still and sweep it left or right.
