Laminated Core

A core built up from thin sheets of metal insulated from each other. The insulation normally consists of a thin coat of varnish.

The outer laminated stationary stator of an AC motor.

Localized currents are induced in an iron core by the alternating magnetic flux. These currents translate into losses which end up as heat and their minimization is an important factor in lamination design.
