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

Hi All,

My metglas cores have come in at last. Here are some pictures of them compared to the ferrite cores I have been using.

Regards,

Ossie

Looks good Ossie!!!!

Hi All,

Please see my latest video here.

My latest Steorn replication motor appears to be running at almost 100% electrical efficiency. I am still using ferrite cores for the drive toroids and the motor runs at about 60 RPM.

Please see the circuit diagram and waveform traces as follows.

Regards,

Ossie

There are so many errors in this page alone that I wouldn't even know where to start, LOL. "Reset current"?  Studying "effective permeability" will help a lot of people here. The core is not a square loop for open magnetic loops, which is the case for the magnet to core interaction. And it doesn't matter because the reason the core is square loop is because it takes hardly no longitudinal applied field to flip it. ... I don't even want to spend the time to help people here anymore because it's a hopeless cause. Good luck! 

Typical Paul Lowrance behavior.  I am not a bit surprised.

Very nice work, as usual!  Close to the speed expected, when you consider only half the amount of toroids as the original orbo, and 4 generator coils...  How long have you gotten it to run before you see any voltage drop in the battery?

A couple questions though, just so I understand the concept of what you are doing.  Why 2 reeds, wouldn't just one of the reeds do the same? Or is it so you can fine tune the pulse width more easily?  Also, why hook the generator coils directly in series with the toroid coils, and not seperate?  Are you using the generator coils to help drive your motor or something?  I am assuming that you have tried the generator coils in parallel and found the way you did it better or something, but I was just hoping to hear more on the theory behind why you hooked them up in this manner?  Also, where is your pulse in this setup?  Are you pulsing between 0 degrees and 30 degrees, or a shorter pulse width?

Great work though, keep it up!  Some interesting concepts and results.

Just want to clear up the discussion/difference between MetGLAS and FINEMET...

From my research on this I can definitively state the following:
1) MetGLAS is an AMORPHOUS METAL (i.e., it is NOT nanocrystalline)
2) FINEMET is a nanocrystalline metal (i.e., it is NOT amorphous, or 'glass-like')
3) MAGAMP is simply a term used by MetGlas to describe cores that are designed for MAGnetic AMPlifiers, thus, 'MAGAMP'.  There are BOTH MetGLAS MAGAMP cores and FINEMET MAGAMP cores!
