Hi All,
here is a new device, that I came up with.
It is using 2 coils at 90 degrees, that is why I call
it Hartmann Orthogonal Generator (HOG).
I was inspired by the free bicycle light system over here:
http://www.freelights.co.uk/how.htmlThere they have a moving magnet on the wheel.
I am having instead of this a driver coil,
that gives a magnet a kick inside a case .
I also have a second case close to it, where a second
coil is wound around, also with a magnet inside.
This second coil is wound 90 degrees (orthogonal) turned
to the first coil.
As the 2 coils are 90 degrees turned around, they don?t influence each
other and currents in each one, do not do any induction into the other...
The only thing, that keeps these 2 coils "coupled" are magnets
that are in each case.
Now the first coil is just pulsed shortly with a square pulse
(in this moment from my function generator,
later models will have an integrated driver circuit powered
by the output power)
at around 10 to 20 Hz.
This makes the magnet inside the coilbox jump up and down and toggle back and
forth forcefully.
As the second coil box is placed near the first box, this magnet motion
is transfered via its magnetic field onto the second magnet, sitting in the
second coilbox.
This second magnet then begins also to toggle back and forth
and thus induces voltage and current inside this second coil,
which is our output coil.
Now these 2 coils work a bit like transformer, only coupled by the toggling
and jumping magnets.
The good thing is, that the 2 coils itsself don?t drag back on each other,
as they are 90 degrees turned around so a current change in one coil, does
not affect the other coil.
Also as the magnet jumps inside the drivercoil, it does not consume
any more input power, it almost stays constant.
Thus the output power could be scaled up by using bigger and stronger magnets
and having more turns with bigger sized wire at the secondary coil.
Here is a video of this HOG concept.
You can see in the primary front coil box a magnet jump up and
down and toggling and in the coil behind it, there is the second magnet
toggling inside this coil bobbin and lighting up a red LED via its induction.
Also parallel with the LED is my scope connected, which shows
the induction voltage.
This concept can be scaled up very easily.
