I am considering purchasing an easypic6 development board and setting up a motor configuration similar to yours. Were I to forge ahead with this, would it be reasonable to expect that I could load your hex file into a chip of like specification? Not sure I am up to assembler programming but I have done a bit of C from long ago.

Your comments and advice on this would be appreciated :-)

Kind regards, nodrog.

Thank you so much for your Reply
I have been so busy working on my motor I haven't been on the forum for a while

I have some very impressive results I am eager to share.

I will give you any information you need I have anew PDF I have created about all of the PIC system

In this setup we are effectively using two transistors to drive the motor coils. These two transistor setups effectively give us the ability to completely isolate the coils from the supply source. This is a very important technique we need to exploit to achieve our desired circuit.




When the two transistors Q1 and Q3 switch on, the coils begin to charge up. For explanation purposes we will refer to coils as if they where charging devices. In some circuits coils are used to do the same job, similar to capacitors.
As the coils begin to charge they produce an electromagnetic field.
This electromagnetic field is produced by the current drawn by the coils from the supply source, i.e. the battery.
What we are going to do is collect the energy used to produce the magnetic field when the field goes into reverse. The moment the transistors switch off, the magnetic field begins to collapse; as the field collapses the energy used on charge up is returned back to the battery source. It is the collapsing magnetic field that produces the induced current in the coils. Only a magnetic field in motion can move electrons in a coil.
The reason for transistors Q1 & Q3 is to isolate the battery from the circuit that charged it during discharge. Because the return voltage is now in a reverse polarity we needed to connect the negative side of the coils at D4 to the positive end of the battery. What we are effectively doing is turning the coils around in circuit in a micro second of time so they can now charge the battery they where only just energized from.
This is a brief explanation of the affect.



The relay provides isolation from the battery during the drive cycle. It also prevents a load situation from occurring that will affect the motor’s efficiency. This occurs at tap point 1 For maximum efficiency the timing of this is of critical importance and it is all done as the motor rotates.



Wave forms are color coded to match Tap Points on schematic.
Yellow Tap Point 1:
The yellow wave form above represents the switch on time for the relay. Notice how the wave form lines up with the beginning of the first green pulse and then finishes at the end of the last pulse. There is no circuit created via D5 back to the battery outside the yellow arrows. The processor automatically controls this no matter how many pulse events you program into the system.
Red Tap Point 2:
The red arrow above pointing to the bottom of the green wave form, represents the switch on pulse time of the duty cycle. The time duration of this wave form is whatever is expressed on the LCD screen of the micro controller. This is only one of the three duty cycle pulses you see present At this point Q1 & Q3 are switched on. Current then flows from the battery source through the switching MOSFET transistors and creates a magnetic field in the drive coils (the red arrows shows the direction of the charge). During this event at tap point 2 the voltage on the anode end of D5 is now referenced to ground, preventing D5 from conducting. This means there is no current path through the diode, or the relay, back to the battery.
Green Tap Point 3:
The green wave form above at tap 3 is the voltage present the very moment Q1 & Q3 switch off. A this precise moment when Q1 & Q3 switch off the magnetic field induced into the coils during the charging process now goes into collapse. As this field starts to collapse the motion of this collapsing field starts to produce a rising voltage coming out of the coils in the direction of the green arrows seen above. Because of the intense magnetic field that is collapsing and the motion of the magnets on the rotor as they pass by the stator cores we see a sudden rise in voltage. This voltage will rise to a very high level, possibly 300 to 400 volts, depending on the type of coils used. As the voltage rises above the threshold of D5, D5 will now start to conduct and with our solid state relay also in a conducting state the voltage surge returning from the coils is on a path back to the supply, i.e. the battery.
Blue Arrow:
The blue arrow represents an area within the wave form where there is no circuit. Nothing is happening – there is no current flowing in any direction. This has now become time within the circuit that you can utilize to tune the system.

Hi Rod,

Thanks you for showing the schematics and the scope shots. Would like to ask the scope settings both on horizontally (TIME/DIV) and on vertically (Volt/DIV)?
It would be more informative.
You indicate PVN012AP photovoltaic relay now for battery separation during the drive cycle and earlier you wrote using a PR32MA11NTZF Solid State relay. The first one seems a bit slower device than the second one, is it still good for the job?

Have you already have some measurement results (input vs output) with this setup you show?

Thank you
Gyula

Hi Rod,

Excellent work!

However I am confused with the scope shot, no offence... but is it inverted?

Which way are the pulses going? Is TP1 On or off?

PWM Time (in mille seconds) – PWM Frequency.
Pushing Button 2 increments the user to menu Position 2. Displayed on the LCD screen on the right-hand side is the frequency of the PWM in mille seconds. As displayed by the numerical characters below, the value on the left-hand side is half the value shown on the right-hand side. This is because the value on the left-hand side is the duty cycle of the PWM frequency. In this menu position the user is able to adjust the frequency of the PWM and the Duty cycle.
The computer will automatically adjust the duty cycle proportionally to the frequency.
The display before you reads like this: in seconds, we are delivering .004063 of a second of a pulse to the magnetic coils, or as abbreviated in proper electronic prefix, it is displayed as 4.063 mille seconds (mille being 1 thousandths of a second and can also be read as 4.063 thousandths of a second). If conversion to Hz is required, by simple mathematical transposition, 1 over .004063 = 246 Hz.
PWM Frequency.



Displayed on the LCD screen on the left-hand side is the Duty Cycle, measured in mille seconds. The display on the right-hand side is the PWM Full Cycle, measured in mille seconds. Now we are concerned with adjusting the Duty Cycle. The Duty Cycle is always proportional to the Full Cycle, as displayed on the right-hand side of the LCD screen, e.g. If the total cycle reads 4 mille seconds, and we adjust the Duty Cycle to engage the coil ignition time of 3 mille seconds, then we must logically assume that the coil is then switched off for 1 mille second. This is the reason that all the measurements are expressed in time in thousandths of a second rather than frequency. In this application total frequency does not apply. We are concerned with the work done by the Duty Cycle that we used to switch on the magnetic coils, and the other portion of the wave form is used to discharge the coils to collect the high voltage EMF. This micro controller will be used to adjust these ratios and find the best suitable times for charge and discharge in order to achieve the most efficient pulse motor application.

good question?

The pulse goes low to turn on the device because it is referenced to ground
across the transistor.

if you need a photo I will make one later

Nope, thats fine. I was trying to remember what you had said about the cap switch out not being on when the coil drive was on... but had not allowed for inverted logic, lol

On <http://www.overunity.com/index.php?topic=10398.new#new> message #400 I have posted a coil shorting jpg of 8 shorts at peak sine wave.

I mention this as the computer might be a hold up for many (me too) and my circuits could be adapted to run the Adam without computer control... just using pots adjust the pulse width and number of pwm pulses. Also just using two matched (same number) N channel fets for top and bottom switching.Any interest let me know... I'm in the middle of a bunch of things at the moment so it won't be instant. Didn't post here as could be OT.

Rod, now if you had been using the arduino uno... LOL, love to get started on that one....

Ron

[coss]

hello
this system have COP>1?

[eternalightwithin]

Yes it does. >>>> COP1 Go and build it. You will get much satisfaction

[plengo]

This thread is simply EXCELLENT. I am getting into it too.

Today I cut an MFD board to 200mm circle and used a motor from and old VCR as a bearings (excellent btw).

I ordered some coils from Rod so that I don't have to fuzz with wrong resistance neither inductance. I am trying to replicate Rod's replication.

In the past I did play with Adams motor with great "success". I got it to run in incredible little current and voltage and really cold, sometimes 5 degrees Celsius below room temperature using a digital laser meter. Unfortunately at the time I did not know how to use or program a PIC micro-controller neither new much about electronics and neither about what that really meant.

Today things are different. I know a lot more about electronics and what it really means and know to program a PIC micro-controller AND I have all I need to make it happen. Back in business again!

One thing I have noticed is that Rod is ONLY using one of the sides of the sine wave induced by the magnet passing by, Imagine when we start using BOTH sides??!!!!

Rod, THANK you man, let's make this OU happen for all for good.

Fausto.

I am very excited about the direction of this research. I have had very interesting results.
Yes I agree the processor control is a bit over complicated I encourage the use of any electronic circuits to replicate this effect. I am more concerned with the principles of the electrical process than the tools used to achieve it at the moment. Just in the defense of this kind of electrical control system. The processor gives defined sets of parameters that are very accurate. It’s very easy to go back to a PWM or duty cycle value and know this is exactly what you are collecting data on.
It is clear in my diagrams that the control electronics run from another power source and do not take into account the energy being measured that drives the Motor. I am looking at this from a much larger point of view than what you see as the current setup. It is clear I needed to break this down into developmental stages solving one problem at a time.

Step one was to look at the Drive stage only?
How efficient can the drive stage become? What kind of control system will this Motor generator require?


I am only a small way along with this work. Already I can see this has promise.

First positive outcome.
I have a DC motor that appears so efficient. Below is One of my many documented test.
Run motor from a 12 volt 7.5 amp hour lead acid battery for 12 hours.
Battery was at a blow average charge when stared.
Battery voltage at start of test 12.607 volts.
All results measured on a bench Fluke DMM.
12.607 volts by 10:30 AM.
12.608 volts by 12:30 PM.
12.610 volts by 5:00 PM.
12.609 volts by 8:00 PM.
12.608 volts by 10:00 PM.
12.606 volts by 12:00 midnight.
By next morning the voltage was down to 12.601 and as the day progressed there was a recovery back to 12.604.

On the motor there are two other coils that are generator coils only. They are connected to a bridge rectifier then to LED resistor series network consuming current generated form the Magnets as they rotate this resistor net work consumes 18 milliamps from the generator coils. There is a load on the motor just to keep things in perspective.

Drive parameters 6 pulse delivered every trigger event. Time duration per pulse
PWM 1.173 milliseconds 852Hz
Duty Cycle 510 microseconds or 0.510 milliseconds



I believe there is a way to create over unity working with know and accepted electrical principles. All tests to this point indicate this to be so. I am documenting this research in l as much detail as I am capable off. I am not physicists, I will disclose all details on this forum and publish all work on other Websites for every one to analyze and replicate.

I encourage the use of any electronic circuits to replicate this effect.

Hello nodrog
I have been intending to answer your question about my motor for a while
We know coils have a DC resistance like a resistor but coils do not behave like resistors in an AC circuit.
The coils I have chosen to use in my Adams’ Motor Generator have a .5 ohm resistance and an inductance of 9 mH (mill henries). These coils were able to create a very strong magnetic field. With that kind of coil resistance it was going to be hard to generate a magnetic field for any length of time with out them melting down. Do the math - they get very hot and pull 24 amps from the battery.
So… why do my 9 mH coils draw only 25 milliamps in circuit?
This gives them a theoretical resistance of 480 ohm.
Robert Adams was right about the concept of cold current reversal. This was the first effect I was able to observe. The Bedini Motor principles were also observed kicking back a lot of EMF.
The coils where doing a great job powering the rotor and producing high voltage and because of their DC resistance, there was plenty of current behind the back EMF.
It became very evident that the Adams’ Motor effect, as we will call it, was only present while the rotor magnet was in direct contact with the coil’s iron core. This contact also needs to be dynamic, not static (in other words, in motion). Timing was of the utmost importance.
A coil of copper wire, when loaded, will produce a magnetic field. However, it takes time for this magnetic field to be created. It does not instantly appear.
Sure… to the normal human eye, when we connect a coil to a power supply we get an instant electric magnet. In reality, it takes time for the magnetic field to appear. While the felid is expanding out of the coil, the resistance is also changing. The very moment you connect the coil to the battery the resistance is very high. It actually takes time for the resistance to come down to its measured DC resistance value. This is why the resistance of my 0.5 ohm coil is different in circuit. Coils behave very differently in an AC circuit than they do in a DC circuit. A coil’s AC resistance can be very much higher in an AC circuit.
In an AC circuit we no longer call it resistance it is now called reactance.
The higher the AC frequency, the higher the reactance of the coil and the less current it draws. Now we are getting to the point of the value of the coil’s Henrys. Ours coils are 9mH, and knowing this value, I could calculate the current the coils would draw at frequency. Theoretically, if I could increase the frequency of the of the drive motor the less current the motor would draw.

We all know that when an electric drill slows down, while drilling a hole in something, it can over heat.
Looking at this basic electrical theory I decided we needed to do two things for this to get close to any over unity.
1. Draw less current; and
2. Generate more back EMF.
I decided to create a hybrid of sorts - the cold current reversal of the Adams’ Motor and the feedback EMF to the battery of the Bedini motor.
I could do this by generating multiple pulses at the point of contact where the Adams’ cold current effect comes into place and generate more back EMF to charge the battery and reduce the current flow at the same time. This was going to need to be very accurately calculated. A fine balance needed to be achieved between enough magnetic field and frequency to keep the resistance high and pull high voltage to charge the battery.
What I think is occurring to keep the motor rotating is that the magnets are attracted to the iron cores by natural magnet-to-steel attraction and I create an interference field that scrambles the attraction on the way out, neutralizing it. Lots more to come … !

Hi Rod,

I am keen to build your controller and wish to ask if I may get a copy of your
code for the PIC.

Kindest Regards, Penno
