Solid State Orbo System

[iws1987]

Hi everyone

I registered here and at another forum 2-3 years ago, But has been a seldom guest here.
If I remember right this is my first post here.

Now I have skimmed this thread, and lots of thanks to many members sharing their knowledge. 

Less thanks to the naysayers, I simply don't understand the purpose of most of these posts (speculative naysayers), except wasting the time of other members. 

But now I got through the posts and got it off my chest.

I have done a few experiments on these effects being the subject of this thread.

Let me begin saying I have visited Steorn before the 1st of april, and the announcement of the SS Orbo at this time was due to Seans humour.

Let me also say I have not so far seen the SS Orbo presented at Steorn directly in this thread.

---------

What I have experimented are some a very basic setups, just a magnet, a toroid and a coil.

The magnet is a neo 25mm diameter 15 mm high N52, and the toroid core is 2 cores sanded on one side and glued together to form a OD 25mm, ID 15mm, length 20mm. The coil used is close to Brooks coil dimensions ID 29 mm OD 48 mm, length 7.5mm filled with 0.2 mm Cu magnet wire.

I found best results with no core in the coil.
Having the magnet flat on the table, the toroid upon the magnet with horizontal centerline and the coil touching the the toroid with approx. 120 degree angle between the centerline of the magnet and the coil.

For the first experiments i used some nanoperm toroid I got from Sean, but I did not like the conductive metal foil in the cores, as it heat a lot at higher frequencies due to losses in the core material.

So the core I used then was as mentioned in a N30 material approx mu value of 5000. I do not consider this optimal, but the main purpose for me was testing the effect, and see how I could harvest the energy.

To exite the toroid I use my uController + a supply and power/signal distributer PCB + a number of insulated MOSFET or IGBT PCBs up to 800V sustained and of own design. These PCBs can operate up to 500kHz. The toroid is sitting between 2 switches like the coil in a window motor.

Sean was talking current, while I want voltage (at least as a first step).

I have studied Hector's writings, and this is the reason for the experimental set I have made. The uController has 7 PWM outputs, which I can use to control the transistor frequency, phase and pulse widths.

If I load the coil with a resistor I get almost nothing, just some spikes.

According to Hector I should use a LC tank circuit at resonance to transform the energy, and that is another ballgame. I have had a 12V 4W bulb lit to full brightness using a simple adapter transformer for impedance matching, The loaded sine was 200V rms.

The next step was to use Hectors diode plug to harvest the energy non-reflective to the load, thus not detuning the LC circuit when harvesting the energy.

This enabled me to light a 220V 15W bulb approx 1/3 lit.

The COP is terrible, as this core material is not suited well. I think e.g. a T38 core  material will perform better. On the plus side is the option of recovering the energy from the toroid. Doing that a battery is kicked hard and charging well. I have not measured how much I recover.

But aiming for electrical output the COP is of no concern so far, I can just say that Hectors teachings once again is no BS, it works as he says, so the countless hours working through his non standard terminology writings has been rewarded. Frequency and precise pulse width is very important.

So now I "just" need a more efficient way to gate the field from the neo.

Here I want to thank lumen for post #118 on page 13. 

I think this has a lot of potential.

As I see it, the field in the magnets and the loop around circuit does not vary much.
The strength of the magnets is set so the "8-toroid" is near saturation.
The gain mechanism is the control coils only enclosing a part of the core. Energizing the control coil saturates the core inside the coil. This results in a saturation of the remaining core, because the "effective core area" is reduced. I also suspect this effect to be much more fast than the transistor operated control coil.

So next is to get some cores to test this hopefully more efficient gating.

I'm not ready to release the PCBs yet. I have also done some Tesla switch experiments, and something weird happens. I have seen 8kV/us gradients, and activated but not resettable protection circuits. After a power down they work OK again. This has to be investigated more. It has even cost me 2 smoked high quality MOSFETs, all 3 pins fully shorted.

The power for the control comes from a net adapter. The MOSFETs and IGBTs are just acting as switches well insulated from the control circuit.

Loaded the same picture twice, here is the second picture.

Here is the diagram, I compressed it so much I could preserving readability, but it is still a bit wide.

I'm working on designing a new controller board able to control up to 16 ISPS (Insulated Simple Power Switches) with 8ns time signal resolution, take input from a quadrature encoder with index pulses for pulse motor applications (up to 8MHz encoder frequency), and maybe also have 3 DDS ICs (no individual drift, as operating from a single crystal).

With this new board I will be able to implement SMPS low and high voltage, rpm and torque control, closed regulator loop for voltage and current regulation and limiting for many different experiments.

I started on this road to get a "LEGO brick" set, being generic and reconfigurable for new experiments.

my latest motor based on ss . I'm very happy with result (very simple electric tiger) spinning and produce energy ...

I know that maybe it should be in orbo motor section but you can treat moving part as generator if you wish

"When they send out some of these boards to SKDB members, we will find independent verification all over the world. Anyone with an oscilloscope and some voltage and current probes can measure this."
