1N4001 and my Alt. Bedini Circuit

Seph, I think you are making some pretty good sense out of the Bedini stuff, great that you are sharing it here unselfishly.

Now I see what you are talking about concerning the 1N4001. If you think about my Alt. Bedini Circuit, the same observation is still true: the base-emitter will be shut off when the trigger coil is charging the battery, as the voltage at the emitter shall be higher than that at the base.

Here you go...



Though it is a little bit more complicated than that... you may be wondering why the low voltage just after TDC is enough to trigger the base of the transistor, but it isn't enough just after the peak voltage.

Well, basically the induced voltage by the rotor magnets just initiates the triggering of the base. Once the base has been triggered then current starts flowing through the primary coil. This induces current in the trigger coil in the opposite direction to the current in the primary and this induced current keeps the transistor open as the coil energises. Once the magnetic feild has almost reached its peak then the induced voltage from the primary isn't enough to keep the transistor active so it cuts off... then current starts flowing in the opposite direction in the trigger circuit (through the 1N4001) and forces the transistor to stay off even if the induced voltage from the rotor magnets is enough to keep it open.

Does that make sense? I made a video explaining the basics a while ago...

Wrong, that is the reason the monopole bedini sg is an energizer and not a motor, the transistor is switching on at scalar south, this generates drag because the trigger current atracts the magnet to the core. Do a reed switch pulse motor and test yourself the difference, the reed switch pulse motor is more efficient if is used with mosfets, and the pulse is right.

With a little ferrite core, the change in magnetic field is proportional and almost in phase with the voltage. There is no delay with a coil with a little stator or core.

The graphic at the sephiroth link is OK, but this isn`t the same case.



I'm boring.

Very interesting seph, i didnt realize it worked like that. So basically what you are saying is that the voltage is out of phase with the induced field strength. Meaning the induced voltage is out of phase with the induced current, because magnetic field strength is associated with current, not voltage, right? So we are closing our switch when current is at its highest potential not voltage, interesting.

Do the test, i put a vumeter, i do the test

Is wrong, and evil, liars.

PLEASE DO THE TESTS!


I have a steel balls core.

DW I have been doing tests for over a year... I stare at waveforms during every free hour I have. All I am telling you is what I am seeing.

Tell me why an Adams motor is more efficient than a Bedini SG, tell me, because the switching seems the same, but this is not true, the switching is different. One is switching in scalar south , the kick is lower, (bedini sg). Adams motor/generator is switching almost TDC, a little away of Tdc.

Does this video help?

Bedini Sine Wave/H-Wave

If it fires on the scalar south then why does the pulse come in half way down the sine wave?

[darkwizard]

I don't know.... this h wave why ocurrs? the transistor is switching in reverse mode?

[amigo]

My guess is that the "h" occurs due to clipping of the sine wave on the base of the transistor, as bias is getting higher.

With the trigger resistance is going down, the diode presents maximum resistance to the current (because the current cannot flow in the opposite direction B->E, the way diode is oriented upwards), it all gets sinked into the base.

Although I think the process is rather reverse, we have the high bias which drives the transistor into saturation, spiking the voltage on the C->E first, then we have the clipping occurring since the bias is coming down and transistor is de-saturating; we get the "h", and then the transistor shuts off as the "h" disappears until the next gate.

Not sure if I understand the question...

The flyback from the collapsing magnetic field is the opposite polarity to the voltage applied to the coil to create the feild...

is that what you mean?

[Sephiroth]

Another great video from Lee which has the strobe on the rotor which shows where the coil pulses in relation to the position of the rotor magnets...

lol... I just watched it again and he explains exactly what I am saying as well

[darkwizard]

It seems to be a problem of the ferromagnetic core material. In an air core coil the voltage is in phase with change in magnetic field.
