    Hi All,

    Just though I would post a pic of my replication of the converter. It is 90% complete. All I need to add are the coils and a bridge rectifier for the output. I have copied the device Bedini shows on the DVD only I have used three magnet pairs instead of two. I have a feeling I will need a bigger drive motor. It looks tiny

    Cheers,

    Steve

    Hi Red,

    Thanks for the info about the coils, I didn't even know there was a two coil version. I am building one very similar to the machine shown on the DVD with the four coils in series. I'm still deciding if I should make them with the three paralelled windings or just keep it simple and only have the one winding.

    As far as the shaft goes, I have managed to get one made out of a rigid plastic. I can't recall the type but it should be a good "axle" as this isn't a torque motor. Also, being made from plastic makes it easy to drill holes into for attaching the coils etc.

    Cheers,

    Steve

    My only question is, do the coils have to be wound in a certain direction for each polarity? I guess I'll have my answer when I go to turn it on. Knowing my luck they will all be backwards or something.

    MIT probably did develop them and then sold them off. Who knows, they probably run the place with them.

    direction of coil wind makes no difference if you are doing a single strand on a single coil. but it does matter if you are going multi stand and multi coil you have to make sure that you have the right ends tied together just like any other generator. If you have just the two coil model that is spinning the magnets instead of spinning the coils you can use two double pole double throw switches to switch from voltage and amperage and ac and dc output.

    Im hoping to build a smaller one myself that will fit inside one of those cd holders. i have the motor for it already. just have to get the generator part made. mounting to the stainless shaft is the hardest part that I have run into so far.

    Everything is based on Raymond Kromrey's US Patent #3,374,376. Start there. The "black thing" on the top was the DC drive motor.

    Thanks Peter,

    I figured it was the drive motor but wasn't sure. Based on what John says in the dvd it seems like a pretty intersting device.

    Cheers,

    Steve

    Just saw the latest EFTV DVD and would and would like to construct a Kromery Converter. Has anyone here done this already or knows more of the details. The DVD was very informative, however it left out a few things. For example, what is the black thing on the top of the converter? (looks like a dc motor to me), are the coils wound for a certain polarity? etc.

    It all looks reasonably simple, however looks can be decieving.

    Cheers everyone.

    Steve.
