Hilden-Brand Magnet Motor

hi Jack,

how about wrapping a long laminate around the magnet many times until you have the desired thickness of jacket? This is how toroidal transformer cores are made.

Best regards

Here are three ways of wrapping the steel laminate along the magnet.
Personally I think Type 3 will provide the best flux return path.
But Type 2 is the easiest one to make by square cut steel laminates.
Which one of these three examples do you think is the best one, Jack?

I have also thought of Alberts torodial transformer idea.
One could take apart a torodial transformer and machine it's height to fit the magnet.
And then unwind the laminate layers to get the desired thickness.

Jack,

Another alternative to using the Silicon Steel strips, like Honk suggests, might be to use Soft Iron wires. Due to the higher permeability of Soft Iron, the core would be lighter.

[Honk]

I believe Soft Iron wires will have to many airgaps that will prevent a good flux
return path. I will use large iron powder toroid cores of grade 26 and then precision mill
the valve I need from those. It's a pretty cheap way to make iron powder valves.

Has anyone tried a composite of pure iron powder say 100 mesh with epoxy pressed mold and cured under magnetic force to train the particles till fully cured?

I have done this with coil cores but nothing like this.
