Here is how it probably works.

Look at the attached picture. (You must be logged into the forum)

The magnet, when it approches the coil is attracted to the coil,
as the reed switch is closed and the generated current is into this
direction, that it supports the attraction of the magnet !
This is the Anti-Lenz opportunity of the Adams motor which we discussed
a few years back also with Greg Watson, if somebody still remembers this! ;)

This is for sure, the shortcircuited current attracts the magnet and accelerates it
into the direction of the iron core.

Okay, then when the magnet is top dead center the reed switch opens !
In this moment the coil makes a huge voltage induction pulse and the voltage
reverses at the coil... !
But as the cap is parallel now with the coil and this makes almost a shortcircuit
to the coil again ( non charged big cap is like a shortcircuit in the first moment)
also a big reversal current flows inside the coil !
This indeed produces a reversed magnet field which will kick the magnet away !

This is probably the whole function principle of the motor !

The twisted wire is only for a show...

You can even make the motor better and capture energy,
if you place a diode in front of the cap, so the charge into the cap can not discharge,
when the rotor is away and the reed switch closes again and discharging the cap again
until the next rotor magnet comes in...

Very clever circuit !

Regards, Stefan.

Hey harti
It's also interesting that the circuit you drew on the left is basically a buck-booster circuit or DC-DC converter.
Draw a positive line coming into the top of the coil and a negative line into the bottom of the coil and you have a classical DC-DC converter booster which can operate with efficiencies upwards of 96% .
This is one of my favorite circuits, transformers are old news.

So here is a better circuit, where you can really run a load with it
and also have a blinking LED with it.

Picture attached.

Hey Harti
It took me a minute but I found a way to explain what Im getting at, in the circuit you drew with the scope shot the voltage rises then reverses when the switch opens this is exactly right. The problem is if you put an ammeter in the circuit you would find the "current" does not reverse at register it remains forward even on collapse of the B field. The current drives the magnetic field-so the magnetic field does not reverse, thus the magnet is not repelled it is coasting out of register with a reduced amount of backdrag because you have shorted the coil.
What Im saying is adams produced a true current reversal, the voltage AND the current reversed, there is a huge difference. I have enclosed a picture (1) is the plot of your circuit-red is voltage-blue current
(2) Adams motor plot-Voltage in red-current is blue.

@allcanadian,

no, I ploted also the current.
i(t) is the current over time in the coil in electrotechnical terms.
t is the time.

Normally I would agree, that the current just only decreases, but does not reverse.
But not so with this circuit, as when the reversed Back EMF is produced
as the reed switch had opened, the empty cap is then directly across the coil
and the reversed voltage is fully discharged into the cap,
so also the current direction in the coil reverses, which will
also change the magnetic polarity of the coil and kick the magnet away !

So the iron must be pretty soft inside the core as it reverses its flux all the time
and the hysteresis losses must be reduced.
This is probably also the case, why the rotor does not pickup more speed !

Scale the coil up and use bigger magnets and my better output circuit can really
generate power and also the rotor will deliver mechanical power !

Regards, Stefan.

Hi Stefan,

I am puzzled by why a short circuited coil is able to attract an approaching magnet?
So far whenever I placed a short circuited coil near to a rotating magnet, Lenz law always reduced the speed of the magnet's rotation... 
Would you (or someone else here) mind explaining briefly this case?

Many thanks,
Gyula

Hi All,
I tried moving a ceramic 8 magnet over a 1000uF 100v capacitor and there is a small amount of current but you are talking a couple of uA.
I also tried a length of twisted wire and even on the lowest scale I could barely see any reading in the uV scale.

One thing I did notice was that the capacitor slowly builds a small voltage if connected to a volt meter.
In about a minute or two it rises from zero to about 500mV.

Hi Mervace,
Nice motor.
Can you post a circuit diagram with component values.

The one thing that puzzles me and everyone else is to what triggers the pulse in the coil.
Why does the rotation speed not increase or is it air friction keeping the speed low?

Regards

Rob

If this circut is OU . we need energy source . All Tesla OU have antena (like his electrical car)
this twisted cables could by just antena.

Im going to have to rebuild my adams motor I think,and see what harti's circuit does for it. I started a thread in pulse motors as I don't like off topics in threads either. Harti could you send your pics to pulse motors/adams revised for reference?

So where the hell is Merv?

Here is the circuit broken up into 2 parts:

case 1 and case 2

case 1 is the approaching magnet inducing a voltage into the coil and
as the reed switch is always closed this is producing a current i(t)
inside the coil that is flowing  from top to bottom through the coil.

case 2 is the case, when the magnet is top dead center and the reed switch
opens for a few milliseconds and then the coil voltage reverses and the current also
reverses in this case and flows from bottom to top inside the coil.
This way also the magnet field of the coil reverses and kicks the magnet away.

When the magnet is a few degrees away after top dead center the reed switch is
closing again and shorts the rest of the Back EMF voltage so the magnet is eaven
more kicked away as the current rises in this case again.

The LED keeps the cap not discharged in this case and can deliver its charge to the load resistor
RLoad where a current i2(t) is flowing then.

Do this system is not breaking thro metal core?
Will by interesting how it works on air core?

George, it will not work with air core coils,
as you need the iron to concentrate the flux onto
the reed switch to open it up,
when the magnet is top dead center above the iorn core.

Also you would not have any attraction to the iorn core when the
magnet is aproaching.

To generate EMF you don?t need metal core , but metal is breaking magnet

My Guess is there?s a circuit from a ?perpetual motion art?
In the very top cross brace. a simple battery, reed switch and coil.

Like this,

The device while running, I bet it would still run
