axial generator with lamination core

(1/150) > >>

Windmill friends,

This forum seems to me the right place to exchange ideas on a test setup of an axial generator.
Now I have 2 magnet rings and an axle.

mbouwer:
Got 51 lamination packages now ( 20 x 8 x 8 ) cut out of transformer sheets.

I think of gluing  49 magnets 20 x 10 x 5 mm on the magnet backing rings ( thickness 4 mm)

odd numbers don't work for magnets.

mbouwer:
Of course.
Then I can go to 48 or 54 magnets.
Or does it make sense to go to the maximum of 80 magnets?

mbouwer:
With 51 packages the space for the coil-legs is 8 mm.
I tend to 48 packages with coil-legs 9 mm.
