Magnetic amplification and neutralization motor by Art Porter

greetings to all
Today I made a change, the power transistor, the work that I showed previously was with the tip 41 transistor, and I replaced it with the tip 122.

Everything seemed that it would not have any change, but when moving the duty signal, the brightness of the bulb increased considerably.

When measuring the consumption increase, so the same in the voltage and amperage focus.

It is a matter of continuing to search and see which elements are more optimal for the best performance to generate more profit.

What if I have to make another coil, since the one I'm using has very little ohms, I need it to have more, in order to raise the BEMF voltage, a value closer to those proposed by Mr. Art Porter.

Continuing with the project
Build a circuit to use the IRF 540 mosfet, and see what happened.
And if it is better to use mosfet to switch signals, I obtain much better brightness, and at a lower operating frequency, as well as less current consumption, the duty signal cycle also varies.

I have been working with 24 volts output on the power. I'm going to try 36 volts, so if I'm going to make another coil, I need 28 ohms, for more induction voltage.

I appreciate your comments and suggestions.

today greetings
I worked on Mr. Art Porter's coil project, I increased the voltage:
38 volts with a consumption of 1.10
48 volts with a consumption of 1.32

and it was to be expected more voltage plus lighting, I try to keep consumption at 1.5 to 0.6 more or less.

By changing the duty signal I get a super bright one, but the consumption increases 2 amp to 3 amp.

In the image that I show you there is more brightness, but I realize that the camera does not capture as bright as I see.

For now I have been feeding it through DC power sources, the interesting thing would be to do it with the batteries and see the operation time, the consumption time and the battery charge, if the BEMF voltage increases the operation of the battery operating the signal circuit, power circuit, coil, focus, would be the most interesting.
Although I have made voltage and current readings, where I have doubts is the measurement of the amperage and voltage BEMF,

The readings of the parameters are done with the MS21O9A, the BEMF with the hook of the tester in alternating current, and the voltage in AC.

The commutation consumption of the direct coil in series with the ammeter.

Something important and that is what I have been working with a single switching of a single polarity, that is, that I only energize the coil in a single sense of the polarity of the voltage application (+, -), I have not worked at the same time the change of polarity (-, +), I think that if I work both directions of polarity of voltage applied to the coil would have a better result? Do you think so?

As I work with a signal generator and I only apply the signal to the power circuit, I have to find a circuit or a way to do how to reverse the polarity of the voltage applied to the coil. You have any circuit or suggestion friends.

Thank you for your attention

Art's BEMF output measurements were all through a Full wave bridge rectifier in D.C.

Thanks so is.  synchro1

The measurement that I take is after the diode.

Since I'm not applying double polarity to the coil, that's why I don't have the other signal cycle, so I can use the full-wave diode bridge.

The application of double polarity to coil I have to solve it.

Something very interesting watching one of Art Porter's videos, he comments that the input power he applied to the coil consumes 9 amps, and he had a 7 amp fuse, (interesting). but the reading he made with his oscilloscope gave him consumption close to 7 amperes.

Today I will perform tests with the largest coil, it is bifilar, one of the cables is 23 gauge, with 30 ohms, the other is 26 gauge, since I have the generator and I can apply the signal well to them and alter the duty cycle, I will see the results.

I appreciate your contribution  synchro1  , thank you
