What to do to get a better loading?

[Werner]

Dear experimenters

Since years I am building different Bedini energizers. They are running very well and they
provide a high voltage of 200 - 300 V and there are the right very small peaks on the oscilloscope to be seen.

But nevertheless I have a question:
Whem I am loading a second battery with any of these energizers it goes very quick in the beginning till I get 12.4 to 12.5 V.
then it goes very slowly and it lasts 40 hours or more to get 12.7V in the second battery. I never have reached 13.0 V or more.
The batteries are new and have nearly 50 Ah. With smaller ones or other cores it is nearly the same problem.

My coil now has 2100 windings and a diameter of 3.15 inches.
It is filled with metglass.The inner diameter is 1 inch.
I have tested many other coils.

The wheel has 18 magnets with a distance of 3.5 inches


Who can tell me what I have to do to get a better loading.

questions:

what gauge wire and its length
what is the resistance of each strand in the coil, should be around 1.2 to 1.5 ohms
what type of magnets
how long is the coil
how big is your rotor in diameter
what current are you pulling
what kind of transistors
what kind of diodes
are you charging your primary battery before every run
are you trying to swap batteries front to back

a 50 amp hour battery needs a large multi strand energiser, a single strand energiser will have a hard time charging that battery. its good for a 3 to 7 AH battery.


I am asking all of these questions because you can build a machine that "works" but is a very poor charger, there are coil geometries and core materials that work the best, and there are size limitations to what a coil CAN do for a given size battery. please post pictures and complete specs.

your coil is too small for those batteries, and the resistance is too hi. 1.2 to 1.5 ohms max 130 to 150 feet of wire

you need to make your wheel vertical, those bearings are not designed to run the way you have it configured

use mjl 21194

you cannot swap batteries back to front without a cap pulser circuit. a parallel capacitor is not the same thing.

buy the SG book from here it will expalin everything and you will get much better charging, you have many things not correct. just because it spins does not mean it is working correctly.

Hello Tom,[ATTACH=CONFIG]1844[/ATTACH]

I do not measure charge current going to the battery, I only measure the primary current draw. a 7 strand SG with 20 gauge power and a 23 trigger will pull around 125 milliamps per strand or around 1 amp on the primary.

charging battery times vary, I cannot give you a number, I have seem 10 amp hour batteries charge in 3 hours with only 1 amp on the primary.

always run a multi strand coil if you can.

your charge current is controlled by your base resistance, not your coil length, increase the base resistance your primary current draw will go down. as your transistor will be on for a much shorter time.
