STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[futuristic]

Can you please explain how did you check if it is metglas. I have many pc power supplies laying around but I have no idea how to identify metglas core.

Tnx.

Thanks Stefan,

No the little 1N4148 does little with the LED in there as the first swing negative is dispersed in the Big LED. Without the LED, it had more work to do. All your ideas above are correct.

Another thing I did not mention is the ability to use that LED as a timing light.  Shine it on the switch area in a low light condition and you can see where the magnet is when the coil turns off.  Works very well!

Something, question just hit me. Sean has NEVER showed the timing or switching of the wheel! What if our timing is all wrong.  What if we should be turning on going in and SUCK in, then TDC turn off like the BEDINI, With no CEMF (In a mechanically correct motor) and very small BEMF due to low turns on coil, the viscous effect and the delay switching in the core IF magnets are at the right spacing would KICK out and add energy to the rotor??  Just a weird thought!!!!!  Arrrgggghhh.

Coffee is a wonderful thing!

What is Steorn talking about when they used to say the magnets were "stopping for a moment"? Do they still say that?

If I remember correctly on first showing on 15th of December he mentioned optical switching on bottom of the rotor.

Thanks,

Dragan

Yes, that is understood but what is the timing referenced Magnet centering on core?  Does his trigger before or after in the cycle?

If it has a black plastic protective case then it is more than likely metglas.  The one I have has numbers on it, but I'm not able to read the numbers to match it with a specific metglas product.  This came out of a very old PC and it probably wouldn't match any of their current product numbers even if I could read numbers.

Has anyone tried a 555 timer to control the pulse width?  We could then try triggering the pulse at different locations and find the optimal pulse width for the highest performance.  If our magnets are too large in diameter then the pulse width will be too long, too small in diameter then the pulse width is too short.  A 555 timer would get rid of this issue.


[Edit:]  The pulse width remains the same at all RPM's.  The pulse duration decreases as the RPM's increase.  Lumen was right about this.  I was saying pulse width while thinking pulse duration earlier in the thread.  I apologize for the confusion.
