Perpedicular is problem by "eddy currents". For electricity it's looks like short in wending. Rotor in asynchronous motors instead have shorts for magnetics field. (sorry for english)

lines of flux and laminations

Hi,
Is it true that the lines of flux in an electric motor and/or a transformer tend to be parallel to the laminations? Why it is this way and not perpendicular to the laminations instead?

Nevermind! :) I see now that the right hand rule (rotating flux perpendicular to the current) explains this as the current would want to be perpendicular to the laminations.

The laminations are intentionally designed to run parallel to the flux so that it has an easy direct pathway and doesn't have to cross the air gaps between them.

It helps to understand why the laminations exist rather than just having an iron core. Study that, then figure out the lamination direction that best accomplishes that purpose.

then apply the same analysis to grain orientation, to see why GOSS (Grain Oriented Silicon Steel) is used.
Then try and figure out how to use GOSS in an E core.....
