"As I recall, the insulatio
reduces either hysteresis losses or eddy current losses in the transformer."

	Eddy current loss.  The non-insulated laminations form,
in effect, shorted turns which generate loss due to the currents
which flow.  Thin laminations reduce this effect at the expense
of less efficient use of the core space.
