The Lockridge triflar coil

[mbrownn]

I forgot to let you know, the multi meter when in series to measure the amps does cause a drop in speed and so must cause a drop in power input. the capacitor exploded after it was removed so I could take voltage readings.

To get more accurate results I need to leave this meter in place when measuring voltage as voltage drop on the battery will increase with lower resistance. this may have a small effect on my result.

What does seem to be apparent is all components must have a very low impedance to get good recovery, a few ohms does make a big difference. I think it would be better to wind my own transformers for this.

I may have stumbled onto the effect that blew my capacitor.

Below is a simple regenerative circuit, the single inductor represents a standard DC motor. The transformer represents the Lockridge coil but built with an inductance 1000 times that of the motor. The oscillations produced when the contacts opened are of four times the voltage and double the power of the original pulse all be it for a shorter duration. Each subsequent pulse is less than the first but will still add to the forward rotation of the motor.

I’m not sure how we would make it but the effect is interesting. If the inductance of my transformer in my previous test was significantly greater than the motor, I believe something like this could have happened and exceeded the capabilities of the capacitor. I placed 1 ohm resistors on all components and the transformer coupling is 50% for a more realistic simulation.

I have carried out some tests and it is obvious that the trifilar coil is not as simple as we might think, the inductance is the problem. This inductance reduces the amount of power in the pulse going into the motor. A bifilar coil can be used to create a coil with little or no inductance, this is also true for a trifilar coil but when I tested this I was unable to collect any significant spike.

There is a way to wind a coil with three filaments that, I believe, cancels the inductive impedance and still collect the spike but this alone does not solve our problem. we also have to match this coil to our motor. With my tests I have been able to recover energy but not enough to fulfill the requirements of a Lockridge type device but it is good proof of concept.

This thread is specifically about the Lockridge coil but I will give you a basic overview.

We have a motor with a regenerative circuit, in the original device I believe it consisted of a non interconnecting star wound rotor with one set of windings being pulsed, the adjacent windings then giving the recovery. Because the recovery. Next we have a tri-filament coil wound round the motor with a regenerative circuit.we have a generator, rectification and finally a capacitor.

If we combine the recovery from the motor and the tri-filarment coil and feed this back to the capacitor that is paralleled in the source, we have the basic Lockridge circuit. It is important however to separate the capacitor from the source battery with a diode as this allows the capacitor to reach high voltage causing a powerful pulse in excess of what the source can provide.

In tests I have managed to reach 50v in this capacitor giving an increased speed with a 12v source however it is clear that all the components need to be matched to some degree to reach our goal.

Does anyone want to know what this coil is?

It is a bucking coil as shown here by J L Naudin JLN Labs - The TEP Project - Bifilar VS Bucking coils

Very Interesting, when I put the figures in the simulator for a starter motor, the power works out at 352w. Ok this is just a simulator so cannot be taken that seriously but interesting non the less

The balance between the inductors, the capacitor and the resistance is critical. It looks easier to make a bigger device than a smaller one unless we increase the input voltage.

[mbrownn]

I am currently using computer modeling to try and work out an approximation for the components. I will list below the effects of altering the components in turn assuming the same motor is used. There is no assumption of energy from any other source, ie radiant. If we get it all well and good but computer models don't allow for that, so it will be ignored.

Bucking coil inductors

Resistance is inversely proportional to voltage so as low a resistance as possible is required so sufficient power will be available to drive the motor

Inductance wants to be as high as possible to recover as much energy as possible but high inductance is high resistance so this will have to be a trade off. Higher frequency and higher voltage helps but i will try to keep the supply voltage to below 14.4v so that an alternator can be used to generate power. This means i will have to increase frequency to lower the inductance of the bucking coils.

Frequency is also a trade off as input power drops with frequency.

Everything about the bucking coils is a trade off, anything that increases power increases resistance and lowers voltage. The only solution is heavy gauge wire for the inductors which will make them large.

Capacitor

The capacitor has to be matched to the inductor to some extent as we need to cause an increase in voltage by lowering the capacitance. This however shortens the pulse duration and will require an increase in frequency which lowers the voltage and power, another trade off. of course an increase in capacitance has the opposite effect.

Commutator

More segments means higher frequency, smaller inductors and larger physical size resulting in more friction and losses. less segments mean bigger inductors and a need for higher voltage and larger capacitors.

Working principal.


The working principal of this device is to power a motor, with pulses, which allows for recovery of energy from each pulse. This energy is then taken back to the supply and stored in a capacitor at a higher voltage than the source. this energy will then discharge before the pulse from the supply battery therefore reducing the duration of the pulse required from the battery.

As the recovery of energy from the coils flows in the same direction as the supply, this too will add to the pulse the motor is receiving. effectively there are three sections to the pulse all giving power to the motor and only one section is given by the supply battery.

The initial stage of the pulse is given by the discharge of the capacitor, it is high enough in energy to give approximately 1/3rd of the pulse duration. This stage could be much more than 1/3rd and is proportional to the bucking coil charge. If we charge it more then we can recover more. In simulations I have achieved 40% of the pulse. The second stage is where the battery takes over, adds a little more to the bucking coils to cover for losses and is approximately one third of the pulse. At this point the circuit is broken by the commutator and no more energy is taken in. The third stage of the pulse is the recovery, as the bucking coils and motor discharge their energy back to the capacitor, current continues to flow for another 1/3rd continuing to power the motor.

Effectively we get a pulse duration of 75% while paying for 25.

Hopefully the losses in the system will be less than 66% because if they are we will have enough energy to power a generator to top up the battery.

It seems that the figures I had for a starter motor were wrong. I got the true figures being 200uH and 0.045 Ohms. When I ran the model with these figures I needed a much higher frequency, 6kHz. Using a commutator with 20 segments means you can switch 10 times per rev at 50% duty cycle. This would mean that the desired speed of the motor would be 36000RPM, obviously this is not possible.

A motor of much higher inductance is needed because using the bucking coils drops the voltage across the motor to Milli volts and obviously the motor will not run on that. Even putting 220v as the supply would not give sufficient amps to run the motor because of the voltage drop. Maybe this is why the original device used a generator as a motor.

The purpose of this coil seems to be threefold

To increase inductance thus increasing the recoverable amount of energy, provide a collector for high voltage spikes and lowering the frequency of switching. It does all this but does increase resistance reducing voltage and current to the motor and thus motor power.

[mbrownn]

The coil does appear to be a bucking coil. A bucking coil demonstrates high inductance for a relatively low resistance, therefore a large amount of energy can be stored and released with minimal voltage drop going to the motor. This coil also has an unusual characteristic, when a third winding is wound over the top high energy spikes can be collected without interference of the other properties of the coil or drawing energy out of the coil.

I suspect that this type of coil is key to many other "free energy" systems as the transient can be extracted without any transformer effect.

My latest circuit.

[Shadesz]

I am following as best I can. I have lots to learn. Can you please post the import text for that circuit?

[mbrownn]

Sure but I am waiting for feedback from other members first. This circuit has all the basic features and theoretically at least, is capable of re using the energy fed into the coils. No need for any claims of a different source of energy. The more advanced circuit does have things in it that, shall we say, is unconventional.

If you want the basics have a look at this thread http://www.energeticforum.com/renewa...-circuits.html.

[mbrownn]

Ok ill give you some basics . the energy going round the circuit is the left graph, the one next to it is the input power The next is the voltage drop before the motor and the last is the current flowing through the blue wire. Only half the current wave is seen by the motor, now you can calculate the motor power and see it is in the region of 121 watts, more than enough to generate the input power.

I just getting my work looked over to try and find if I got something wrong but it looks good to me.
