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

I wanted to bring to light a problem with winding toroidal coils for this use.
If you wind a coil with two layers, you should not continue to wind around the coil, you need to wind until you reach where you started, then reverse the direction.
Not the direction you are looping on the core, but the advancing direction around the core.
If you do not do this, you are creating a coil that will in effect have two loops of wire that are susceptible to BEMF from the magnets!
That's why everyone can show some BEMF on their coils.

@Bruce_TPU,

The solid state Orbo produces high voltage at low amperage in the generator coil.
So I need to make a impedance match or step down transformer to be able
to use that power for something. But the method works! The unit DOES produce
output power in the generator coil.

In my motor test with magnets on the toroid,
the RPM did go dramatically UP and the input usage went DOWN.
I have no video but it is easy to test for everyone by themselves.

Hi Groundloop,

Great information, thank you!  You might consider using stranded or litz for the Solid state generator core, making the coil with a series of strands in parallel.  Should increase amperage and decrease voltage.  I also loved the idea that was given earlier to increase the magnetic flux.

What size wire did you use for your generator core, and what was it's approximate length?  Thanks!

@ALL
Happy New year to all!  Please find attached pictures of my Steorn Magnet motor being built.  I am winding on my third toroid, and I made the design flexible in design with everything removable.  I have the toroids held between two wine bottle corks.  I have a feeling in the next few weeks all of ours will be changing radically.

Cheers,

Bruce

So, does using a lower Permeability ferrite core material have any potential negative effects for an eOrbo set up?

Hi,

The torque for this motor setup comes from attraction between a magnet and a ferromagnetic core and I think you surely get less attraction force to a core with a permeability of 20 than to a core with a permeability of 1500.
So I think this is the relationship.

To choose a good core for our job here you have to select cores with the lowest saturation values, among the ones with a permeability over several hundred or higher.

@Bruce_TPU,

Thanks. Any you got a nice motor setup there.

I posted that information back on page 60 in this thread.
There I also posted the core sizes etc.

Alex.

Would it be more efficient to utilise more than one side of the toroid ?
