Converting DC to AC

Optional set up, But, It is much safer to step up a 12 volt or 24 volt battery than to use 10 batteries.

Turn using Small DC Free Energy Motor or such..

Make a safe box to hold batteries, build it out of /"to 3/4" plywood. Connect all fuses or circuit breakers outside of box so hydrogen gases will not explode when charging. Charging produces explosive gases.

Brushes should be heavy duty, if not, add more wire yourself to the brushes so they will carry more amperage. More amperage means more wattage output, all wires should be heavy gauge to match what desired wattage output you want. Container can be any size you want. Brushes and contacts should be first tested for as long period of time then oil added. Use a non flammable oil such as baby oil or vegetable oil. If you want 220 volts to run motors and 220 appliances add another 10 batteries separate banks and converters, that means you will need two converters and an experience electrical man to help you if you do not know how to hook up.

Oil Commutator Switch for Alternating bC to AC

Turn an old 12 vdc 5 amp or 40 amp industrial motor into an Oil Filled Commutator DC to AC switching apparatus.

The brushes and contacts will be emerged in baby oil or vegetable oil to reduce or eliminate sparks and heat loss. The motor must be taken apart and the rotor wires that make up the electromagnetic motor can be taken out, you must then add additional ring contacts. Or simply use the container and build our copper pipe commutators as seen in these plans.

As the Commutator turns the incoming 120 volt DC is switched back and forth to the AC Pickup rings, a second set up AC brushes collects the AC.

Incoming amperage from the batteries must be controlled by using fuses and chokes and the proper wire size. if you want 30 amp output use a wire that will handle 30 amps. Now seal all holes and assemble and fill the motor stator container with oil. (It maybe a good idea to use a non-flammable oil such as baby oil or vegetable oil.) or you can simply drill small holes in the bottom of the motor and place the entire motor in a solid can filled with oil. the oil will then fill the motor container and surround the brushes and contacts

Or you can simply construct your own container housing as so: Container can be clear plexi glass plastic so you can see what's going on inside, and the top and bottom plates are steel or aluminum laser cut to your own special size. you can still use a shaft and commutator contacts from an old DC motor. Be careful 120 vdc has more amperage power than your house that is why it must be stepped down to safe levels. (The Amperage ) Use house Circuit Breaker Boxes. And Again Always Use Rubber Gloves. Be safe!

INVERTER OPTION #2

Wires are not shown connected to help show brush assembly

This is our 5,000 watt inverter design, this is a foundation to work from, of course you can build it to any wattage you desire. For high wattage such as 5,000 watts, you must use fat wire and brushes, ( Large gauge wire ) this design can also be made non-mechanical by using electronic switching, but we wanted to make it easy for just about anyone to build. The commutators are very easy to build, it may look hard but it is not. We use our own design using copper piping and J-B weld epoxy, both are available at any hardware store near you I am sure.

The commutators are simply an on and off switch.

when the commutators hit the front brushes, the capacitors are charged with 12 volts dc each,

Then as the commutators spin toward the back they shut off the front 12 vdc charge for the caps and they then spin around and hit the back brushes, which connect the capacitors in series and step the Voltage Up tO 120 vdc. The drawings do not show the lull ten brushes needed, we did not want to make it iook to complicated. _A/ —

Wires are not shown connected to help show brush assembly

Sorry the drawing does not show the full ten brushes to obtain 120 vdc step up

You will need 10 capacitor and diode banks stacked one on the other. Each capacitor is rated at 25 volts x 23,500 uf a 25 v x 4700 uf = about 100 watts output.

5/16" steel collar, epoxy to commutator

The #1 and #2 brushes must not be electrically connected, The epoxy under each steel brush holder will insulate between the steel square pieces and the aluminum. Make sure to spread the surface with an even coat of epoxy. Epoxy glue each steel brush holder assembly to the aluminum brush holder base, part "G". Then spray paint.

The Brush assembly acts as an on and off switch and must be timed so that the motor runs smoothly and not against it's self. The commutator is special made, and as the commutator rotates the brushes hit the commutator contact bar making a complete Circuit.

Use a very fine hacksaw blade to cut spacers, fill spacers with epoxy and sand smooth.
