Thane Heins Perepiteia Replications

Ok then i_Ron.  It's far from accurate, but you get the idea.

Ooops, I got my clockwise and anti-clockwise mixed up. :S

If anyone here is confused, let me shed some light on the situation.
For a purely inductive coil, Tinsel Koala and iRon are correct. (Voltage is zero at top dead center)

Thane is claiming voltage is not zero. This is because Thane's high voltage coils have a significant capacitive component, due to the larger number of turns. As the magnet approaches the coil, this capacitance is charging up, so at top dead center, there will be a voltage. The true circuit here, is much more like a LC circuit (or more accurately, RLC circuit), where voltage and current are no longer in phase (power factor).

Derricka and Larry,

Yes I am open to this... but it has to be explained against the actual coil operation. There are two generated peaks, one positive and one negative. To just focus on the one peak that might be delayed until TDC and not account for what is happening to the other peak is imprecise.

What my contention with Steven and Thane was in their view there was only one major peak at TDC. My concern with Thane's presentations are that he has only ever stated DC coil resistance, never Henries, never A B scope pictures of HV coils with HC coils showing any phase delays. It takes major amounts of capacitance to make an LC circuit yet no numbers for this supposed capacitance have ever been shown.

But to my original question, I think Occam's Razor applies to the answer.

Derricka and Larry,

I was wondering more along the iron theme. What about the propagation delay of the flux in iron at these speeds?

The reason being, if you missed my earlier post, when I used Somaloy there was no core loss reduction...rather an increase in draw with the coil shorted.

OK, the first test with the laminated core and a 63 ohm coil... with the circuit open the draw was 15 watts. With the coil shorted the draw was only 4.42 watts.

However, with the Somaloy core the draw was only about 4 watts to start with and shorting the coil increased the draw!

This test should indicate that it is iron that is required, not capacitance.

So what I am saying is, if the flux buildup in the core is delayed then so also will the voltage buildup in the coil… in respect to the magnets position.
