The Lockridge triflar coil

[mbrownn]

I forgot to mention, it is unlikely that we will get a universal motor into overunity as they are usually 35% efficient so if we get a generator of higher efficiency that has a similar build, BINGO

Now you know why they build motors with such low efficiency hehe

Yes well that is why I'm building the Tesla generator. With the setup you
describe what would power the rotation of the armature? I think if you allow
the field in the field coils to collapse the armature coils won't generate or the
armature will slow.

Testing it would tell, simulator probably wouldn't deal well with that.

Also if the transformer action is used from a multifilar coil the flux will be less
and the input will increase in line with what is drawn transformer style
because of the drop in flux allowing primary current flow to increase, therefore
when the field collapses there will be less joules to collect as well because of
less flux, that's to my way of thinking anyway. I could well be wrong I'm just
using logic I don't have the figures and formula's to back that up.

the trick here is the speed, with a 50% duty cycle on the pulse the second half is the inductive kickback with the voltage returning to zero, the transformer does the same and also the generator. Its a balancing act. Once our load goes too high the motor will stop but our bigger problem is too low a load as the motor may race into self destruct mode.

As the output voltage and current will be higher than the input due to having more turns, the motor would continue to accelerate until it exploded or melted if not controlled.

I suspect the transformer coil is at 90 degrees or so to the field coil but on the same stator section. If the transformer action opposes the generator action we will need the generator on a separate magnetic circuit, hence the split in the case of the lockridge. It may be that this transformer action is then fed to the generator circuit via another coil in the generating half reversing the polarity if required, hence 4 coils and the motor appearing to be a conventional four pole.

The rotor is the old fashioned wave wound with every other segment on the commutator being blank.

The motor is not compensated so inductance will be high at low speed, as speed and as the load goes up the inductance should lower due to the transformer effect just like a compensation coil.

This is all theory too, we will be testing soon on a standard motor/generator and using the results to work out the next step. Once we have the thing how we want we can then rewind the rotor.

I will post results on the lockridge thread when we have them.

Keep asking those questions it helps me work out what I have to do

why do you try to lift open doors ? There are patents describing overunity motor-generators based on modified rotary generator schema.

I am not sure what you mean. I am happy to look at all patents related to this subject, the problem is knowing which patents to look at and also understanding them.

When I was describing how I believe the lockridge must work to another forum member, he said take a look at this patent. It was the US 3913004. I was so happy, it is obvious that I am on the right track and my theories were not unjustified. Although the patent referred to a different device that has a different rotor, stator and geometry, its principal is exactly the same.

The problem with patents is that there is other things about the device that are not included in the patent so that even if you read the patent you still cannot build the device and make it work. That is why the dynamotors you can buy are not overunity, although some may be.

I have spent several years now researching, building simple models and testing and I have been able to eliminate many possibilities. Its not that many of these did not show evidence of overunity, they did. its just that the energy was coming out in the wrong form, ie heat and not mechanical or electrical power. I am closing in on how it is done but I wont say that I know everything, as I clearly don't, but hopefully I will soon know enough.

The objective of this thread was to look at the workings of a trifilar coil to see if that could lead me in the right direction and it did help a lot, but it still left open many possibilities and I still do not know what configuration the trifilar coil had, as it depends upon what is needed by the device.

If you know of relevant information please pass it on as it may be something I did not know or have overlooked.

Yeah that's an exciter/motor/generator all working from a battery. Pretty much
what I want to build. Here's the kicker though. Power is not energy or work.

If we read in the patent you linked, column 5 line 25, quote "thus, the output
voltage potential is kept to a maximum while the current is drawn as required,
within the capacity of the unit design".

If it said method of increasing energy then it would be more interesting.

I don't think I answered clearly last night as I was tired.

We have a rotor similar to what peter had us build on the lockridge thread with a blank segment on the commutator between each live one. The power brushes set up so we have a 50% duty cycle pulse. recovery brushes are placed as required. the field and rotor are wired in series but it is not compensated in the normal way with the opposite field coil. As the speed increases we will reach a point where the reactive time is the same as the input time. at this point we have a triangle wave on our generator winding and a triangle wave on our transformer coil. Our output will be continuous but of varying magnitude and possibly polarity. I hope this explains about how the motoring works as it is very simple. It is 50% duty cycle with recovery of the inductive kickback.

The output of the generator is proportional to the power flowing in the armature but the power in the field coil has to be varying so we have a transformer effect.

I understand what you are saying about the flux but by placing the secondary winding of the transformer at 90 degrees we may mitigate some of the flux problems but we need to test this.

As the power coil and transformer coil are separate hopefully any increased draw of current from the transformer will increase or at least maintain the torque.

I hate the legalese of patents, why don't they use plain English. This patent is a different machine to the lockridge and its gains are:-

1) efficiency, ie that there is only one set of iron and friction losses for three functions

2) A transformer action and motoring action at the same time from the same input.

3) and most people miss this, inductive kickback

The principal gain of number three is x2 and the gain of number two is x2 so we have 2x2=4. In the wording he is indicating we have a x3 output or 75% efficiency. I calculated that we would have a x2.7 output which isn't that far out. He is saying increasing energy in lines 20 to 25 on column 4.

Its time to resurrect this thread

Its time to resurrect this thread

It is becoming clear that the location of at least one of the coils in the trifilar coil is in series with the motor. Its purpose is to provide the voltage to overcome the inductance of the motor so that the current can flow.

To understand this you will need to watch the video by David Squires Advanced Motor Secrets by David Squires No this is not an ad for the video but to get people to understand the function of this coil. The video itself says nothing about the lockridge but says a lot about how it works.

One problem with pulsed DC motors is that they require a higher voltage to run at the same power as a normal DC motor.
