I wanted to invest in a CNC coil winder and couple of EI lamination stacking machines. I'm using a lot of transformers lately for my projects and DIY kits that I sell, and I think starting making my own would be worth the effort.
But it seems as the stacking machines that I'm interested in can do only 0.5mm laminations or 0.35mm - they can't do both.
This means I have to commit to the grade of lamination before buying the machines.
I want to make power transformers, audio output transformers, and chokes for tube guitar amp projects.
I've done some research, and it seems like M6 grain oriented steel (which is 0.35mm) would be the optimal choice for audio application. So the stacking machine for thinner lamination would be better.
(thinner lamination mean less losses. Also the grain oriented steel is more efficient).
But are the other things worth considering? Could thicker laminations have an advantage too? Besides being less expensive.
It seems like the transformers I have now use thicker laminations. But for example Edcor uses M6 grain oriented steel for their transformers.
