Has any of you taken a look at the lockridge device?

I think I have worked out how it may have worked, anybody interested?

I think we may be able to replicate some of the principals with a fan but to be fair we need a trifilar wound motor.

Don't we need brushed motor for lockridge device?

Yes the lockridge device has brushes as it is mechanical timing. this has many advantages over electronics but disadvantages too.

Using the fan we can test out the premis of pulsing a coil and collecting the radiant produced from that and using it to pulse a second coil.

This would result in more mechanical power per watt consumed as we would be using the same power twice. Then we could measure the amount of power in the second coil's spike by charging a battery with it.

This is one of the many principals I believe are used in the lockridge device.

If we lay out the stator of the fan in front of us so that it resembles a cross and wind the coils trifilar, clockwise and anti clockwise as we go round, two of the windings would be used as in the Imhotep fan. the output of the diode on the power coil could then be wired directly into the third winding to create a bigger magnetic pulse.

Test 1

Run the fan as the standard bedini circuit with the third winding unconnected, measure the power consumed and the power placed in the charging battery. Take note of the motor speed.

Test 2

Run the fan with the output connected directly to the third winding and use a diode to collect the spike from that and use it to charge the battery. measure the power consumed and the power placed in the charging battery. Take note of the motor speed.

Test 3

Run the fan with the output connected to a small capacitor with the positive also connected to the third winding and use a diode to collect the spike from that and use it to charge the battery. measure the power consumed and the power placed in the charging battery. Take note of the motor speed.

This would test motor power, COP and if I have the capacitor in the right place.

It would not be the Lockridge device as some other areas are clearly different.

If the mechanical power is increased I would expect a similar fall in output to the charging battery so that the COP would be similar or slightly worse. If the COP increases then I would be very happy hehehe, I dont think it will be.

Do you think you could build this and we can compare notes before I go to the next stage?

I dont know the power of the Delco remey generator but its cop is a little over 1 as the output is 300watts usable power while running itself. A practical overunity device.

Both pulsed with same brush?


This is interesting experiment though. I would use my stingo to drive stepper motor with more than 3 terminal.

To drive stepper motor, I only need three wire out of 5. I can get radiant enough to charge 2V a second on my 10000uF/50V cap. Then I would need a second transistor to use the same trigger as the first to drive another wire with the charge collected by the cap.

Will post the circuit when done some thinking....

Sorry, I don't think I can replicate with stepper motor unless there is complicated mechanism for dumping the capacitor charge. I forget that in stepper motor all wire interconnect each other. So trifilar or more is the way to go.

Just completed my first test. the motor power was up greatly with less input power but the charge was very slow, much worse than before, just as I expexted.

my next test will involve a new winding and a double transistor circuit.

load this into the falstead simulator and you will see my new circuit.

It should increase the motor power and output by around 70% for the same input and should be closing in on a COP of 2. Its a double bedini circuit, the second being powered by the first via a capacitor.

timing should be automatic but we cant do this with the fan easily but its worth a try.

The top and bottom arms of the stator will be the first coil and the left and right arms the second.

I need someone to replicate the device to confirm its performance. it will be a while before i have it working because i need more wire but hopefully not too long.

this circuit is much closer to the Lockridge device

what do you think

What you compare to?

I see 4 winding? I thought one winding act as a trigger for both?

You mean increase of motor speed and charging output?

What is the minimum winding for each coil? 10?

If the left and right arm have CW, I should wound the top and bottom CCW?

Compared to the standard Bedini fan.

Yes, now instead of a single trifilar winding we have two bifilar windings.

On the Lockridge device we do not have the recovery coils to switch the device as the switching is done by the commutator, so this just counts as 2 separate coils being switched in the Lockridge device.

The power comes from the first battery, through the first coil and charges the capacitor. At the same time the radiant spike pulses the charging battery. As the magnet passes over the second coil the transistor switches allowing the energy stored in the capacitor to power the second coil. This energy will be lower than the original supply by about 30 to 40% but is energy that has not been used and can give an additional kick to the motor as well as provide another spike.

We can add additional coils and capacitors until all the energy is used up getting extra motor power and extra spikes for no additional input.

I admit that the original supply will be a little bigger than on a standard fan but I think the benefit may be worth it.

If this proves to be the case then all we have to do is work out how the third coil is used on the Lockridge device and we will have it.

The first test shows that the lockridge does not have a single trifilar coil but two single coils with an additional coil of unknown purpose

I see. I thought it would be something like this bellow:


Not sure if it would work though.

edit: attachement deleted because it is wrong.
