Power ratio over one

Hay Gyula:

I have restudied the instantaneous numbers in the T1 and T2 time frame and there is current. If you have the waveform browser, in the save as section, there are other formats to choose from, other than Excel.
I appreciate your input.

Here are the next 2 pics David posted

To me it is not yet clear how these
rocker electromagnets work and
where there is any magnet at this unit ?

Looks to me like these are just  more views of the  teeter board and switches  ....... there is a  similar  view on reply  27

I believe that that waveform you are referring to is with a 100k ohm resistor. The device works the same with LEDs or a resistor, Or using both at the same time. I understand what you are saying about the loading. The part that confuses me is that anything else placed in series has no effect.
Your input is valuable. If you like I'll send another attachment using just LEDs, and I'll put 1.5 volts to it so the readings are higher. I'll use a cap on the output so the wave form is a little cleaner.

I really appreciate your input!

Hi David,

I changed your sentence green above and I ask that you mean you connect a bulb for instance in series with the LEDs and find it has no effect?  You would expect the bulb to flash for a moment when the LEDs do?  Is it what confuses you? 
If yes, then let's take an example: you have, say, 60V peak output voltage induced in your coil and you use 18 LEDs in series. If the LEDs have 3V forward voltage drop each, then it is 3*18=54V from which voltage level the current starts flowing already but you have a 6V extra (54+6=60V) and if you would have a 6V bulb and this bulb would give out light at 10-15mA current@6V, then it would light/flash up a little, ok?  If it is a bulb designed with higher current need, say, 200-300mA or higher, then it will probably remain an unvisible light source in your setup. Why? Because although the LEDs dynamic resistance will still dictate the current, their very steep voltage limiting characteristics at the 54V value will try to consume the 6V difference and the bulb would merely serve as a low ohmic resistor, with little (i.e. not enough) voltage drop on it for lighting it up.  LEDs are excellent voltage stabilizers/voltage limiters  just like Zener diodes!

I also greencoloured your sentence above and ask how much current you mean and what was your output load exactly when you found current during T1 and T2? (by the way did not you mean T3 instead of T2?)  Also, what output voltage level did you have?

Hay Stefan:
Now I understand your question.
There is only one electromagnet, and that?s the driver coil. The switches, just reverse the power going into the driver coil. When power goes into the driver coil, the permanent respond by rotating forward. In the forward movement, the front two switches are closed and the back two switches are opened. When the front two switches are closed, the power is reversed, causing the permanent magnets to reverse.
