Bedini Coils

[TeeGee]

Hi, I'm involved in building the Bedini Motor with the three coils around the perimeter. The PDF file I have explains that each coil is 5 strands of #19AWG wound into a rope, the length is 5 x 120 feet of wire.
Does this make 1 coil or is it enough for the three coils.
I understand the length will shorten when the rope is twisted, but the description is a bit vague about how much wire is needed. The construction of the formers is straight forward but it does not say how many turns there are on each coil.

Thanks Tom

What schematic are you building? SSG?

Depends upon how big and how many turns are required

It might help if you can attach the PDF

The plans!!!! are in chapter 6, Patrick Kelly's , Practical Guide to Free Energy Devices. Thanks if you can help.

according to the PDF - This will make one coil.
your other 2 coils will have only 4 twisted wires each so that each coil/spool has 4 power winding's and the one trigger for all 12 transistors.
I recommend not skimping out on the transistors as this builder did.
I also recommend you start with one coil with only one transistor on it. play around with it and get comfortable with how to tune it. this is one of the most important parts. also if this is your first build - use ceramics. neo's will allow it to spin, but charging will prove to be elusive if you do not know what you are doing.

Thanks guys

Thanks for the help, and yes I have upgraded the transistors and have some bits ready to make a single coil motor first to set things up.

Hey,

I have to agree that starting with multiple power coils firing transistors is not
an easy way to start tuning, Patrick is spot on with his tips for single strand.
Neo magnets are a pain due to the large field that can easily cause
self-oscillations of the coil (high pitch squeal, very annoying sound )
However, they do have a stronger field and thus produce more induced
voltage/current. (just a pain to tune compared to ceramic ferrite magnets)

If you are going to use multi strand coils you will need to impedance match
the coils, transitors, diodes and resistors to obtain the greatest efficency
in the output.

Bedini recommends the MJL21194 transistor and the r-charge kits use MJE
series in the TWM I just recieved. But really the transistor utilized will be
determined by the amount of voltage/current produced in the magnetic
switching of the circuit. (plus if you used heat-sink or not)
