For the record I dont believe in OU. Or perhaps to put a different spin on it, everything is OU. That may be a little hard for some to grasp. We live in a macroscopic world in which perpetual motion is supposedly impossible, while in the subatomic world perpetual motion is obligatory.

The fact that the world hasnt stopped spinning for some time now is proof enough to me that perpetual motion exists on the large scale just as it does on the microscopic level. People say it cant be done, I say you cant do it because you conform to mans laws, and not natures laws.

When you take into account all forms of energy with a larger perspective and an open mind you can see that if it is never created or destroyed, merely transformed, then there is never a loss! What you see as a loss is simply your inability to detect WHERE it goes. Underunity is also impossible! You forget to take into account WHAT it transforms into. People only consider energy "energy" if it useable to them in its current form. Thats just narrow mindness and ignorance. Tap into the great energy source which binds this world and you have unlimited energy at your disposal.

Anyway enough of that.

Yes it would seem that if 24 amp hours worth of batteries are charged for 18amp hours of input then there is definately a net gain or COp over 1. Not factoring int the mechanical here of course, just referring to the transference of electrical energy from one battery to another. The real test begins when you load the batteries that are charged on the back end.

My IROL is what I use for that and so far great results. The batteries hold up quite well under 1 amp discharge. As long as the monopole runs @ 1 amp while charging them.

Regards

Well said, I could not have said it better myself

Putting it simply if I have a Bedini motor that consumes 12v at 1 amp, I have a 12w motor. If the efficiency is 80% then the mechanical output is 9.6w. If I collect the back EMF and charge a battery there is a proven near 1 to 1 charge rate. so the total output is near 21.96w or a cop of 1.8 to 1.

Where has the extra energy come from? The environment

No energy has been created or destroyed.

If I improve the mechanical efficiency of the motor the cop will improve by the same amount. If I improve the collection of energy from the environment then again the cop will improve.

This is our goal.

So how do I increase the output of a Bedini fan? Make it bigger and more efficient.

Multifilar coils are reported to improve output as are recovery coils so now we will see if it works.

I am now building a Bedini fan type motor with a 3" rotor. The motor used is a 240v ac induction motor. I have removed the coils and i am replacing them with 7 filar wound coils. They will be wound clockwise at 0 and 180 degrees and anti clockwise at 90 and 270 degrees connected in series as you go round clockwise. the above process will be repeated at the 45, 135, 225 and 315 degrees. There is also room for 8 additional coils to be placed around these coils in the stator, these will be recovery coils bifilar wound. When finished the appearance of the wound stator will look exactly the same as the original stator.

The rotor will have 4 ceramic magnets with north then south poles as you go round in a clockwise direction.

The end result is like a Bedini SG motor with two 7 fillar wound coils with 2 north poles on the rotor and recovery coils which can be configured to the best output. It should have more torque and speed but I can see many problems.

There may be cogging because of the flat magnets. Maybe the coils will interfere with each other etc etc.

Any advice in this matter would be appreciated.

Hi Mr Brown.

It would be helpful to see some pictures. 4 magnets that alternate polarity will only give you 2 on pulses per rotation, unless you configure it for bipolar switching. Or have a separate circuit that switches the souths. I would encourage people to build their on machines from scratch if possible. Decide on a rotor and get it router cut or machined to suit the magnets selected. Use good bearings and allow for upgrades at a later time. What could be most beneficial is if you decide what principles you want to test and how you are going to go about testing them, with a design that allows you to test as many ideas as possible.

I have been building this window motor now for over a year on paper, and partly in practise.

Yes your right it is like two poles on a monopole motor.

If I understand my stator design correctly, I will be using both poles on each of my coils which will increase torque. Because each coil is divided into four segments like in the Bedini fan project there will be 4 pulses per rev on each coil giving 8 pulses per rev with two coils assuming we don't have any oscillations. The Bedini fan does oscillate to give many more pulses. We then multiply this by 12, the number of power windings in the coils to get an idea of what sort of output to expect.

I am expecting that the motor will run away with speed as the fan does when the blades are removed

I am working out the size of wire to use for the coils as this is limited by the space available in the stator and I want at least 400 turns per coil or 100 turns per segment. I found that worked well in the Bedini fan. Remember each coil is segmented into four windings in the stator just like the Bedini fan.

My choice of using the standard induction motor is for two reasons. Ease of manufacturing and I believe that motor designers know more than me about how to get the lines of flux passing between the rotor and stator. Additional benefits are that the bearings will be very robust and everything perfectly aligned.

My objective is to produce a pulse motor that is capable of turning a small magneto or dynamo so that I can improve my COP. If this works I will scale it up to produce a much bigger unit. ;)

I anticipate a power consumption of around 36w at 12 volts based on my experiments with Bedini fans with similar bifilar windings.

I cannot send pictures yet plus the only thing to see is a stripped down 4 pole induction motor, several Bedini fans and some ignition coils hehe.

PS lets dispense with the Mr Brown thing. Call me Mick ;)

Thanks to a little help from the Sorcerers Apprentice have learned that I will have to use 4 north poles on my rotor to make the motor work. I will use 8 magnets arranged north then south to do this, all the other aspects of the design look like they will work as far as I can tell

Talking done, I will have to start making the 7 filar wire and wind the stator now

I have completed the first prototype fan with recovery coils. it is working well. I need to condition some batteries to do a test on it and that will take some time; however i have made an interesting discovery.

using my new fan with the Bedini side wired as normal and the recovery side working through a bridge rectifier charging another battery, i decided to slave an ignition coil across the power winding of the Bedini circuit. This increased both input and output as normal. I then run a wire from the -ve terminal on the coil to the HT output on the coil, normally nothing happens and when i short it out I get a drop in output.

This time i got an arc, and a HUGE increase in output volts to the charging battery.
Over 200v. I have checked with the scope and found no additional signals. this voltage is only seen on digital meters and not on galvanometers. There is no change in input power either. There is radio interference.

Maybe the radio interference is causing the voltage readings and there is no increased output, I will have to run tests to make sure but I can use this as the power source for a Gray tube.

The lack of resources can make things difficult, but if you are looking in the right places you can score some free wire. Microwaves and most power tools will have some inside, but they can be trickey to remove.

Hello Mick,
I think the power tools are too hard to recover wire from but the microwave mains transformer is easier. Instead of interleaving the E's and the I's laminations together, all of the E's and all of the I's are just stacked together and lightly MIG welded across the outside. A good whack across the weld with a sharp cold chisel will split off the "I" set and you can lift off the coils. My nephew does it all the time sell the windings as scrap copper. Most of the coils that I have seen have very little varnish on them so they should unwind easily. I did see somewhere on the net where some enterprising person left the primary intact and wound another secondary to make a conventional "electron flow" battery charger. While scrounging in the microwave take the cooling fan it is another source of un-varnished thin enameled wire. The magnetron for two very strong ceramic magnets, the door interlock microswitches and the thermal circuit breaker on the magnetron housing.
If you want a neat digital timer that is programmable in 1 second increments up to 99 minutes and 99 seconds, with isolated relay output then snavel the whole right hand front panel section. I can send you some images etc if you need assistance in setting it up, it is very easy. The hardest part is finding a neat wooden/plastic box to fit it into. Also take the 2000v 1 or 2 microfarad capacitor and the 2000v diode. Make sure the capacitor is discharged (short it out) before handling it, as can hold a lethal charge, some have an inbuilt discharge resistor.

Another source of thick enameled wire is out of car starter motor solenoids, it is not very long but it is never varnished so it recovers easily. In fact a friend of mine has suggested using the solenoids just as they are for a Bedini radial coil setup. They have two coils one to pull the plunger in and the other to hold it in. The hold coil is made of thinner wire but is much longer.

Another enameled wire source is the degausing coil around the back of TV and computer CRT tubes, long but a bit fiddley to unwind.
Regards Ricco

Thanks for the advice, All these things are readily available here, its just stores like radio shack and Maplin are not.

I will be dismantling some microwaves for other experiments.
