Lamination on electrical machines

      Why the cores of the electrical machines are laminated instead of machining from solid block of steel?

      Hello @cblair ,

      The cores of the electrical machines are laminated and are also insulated to reduce the induced circulating current also called eddy currents.

      Hi @rtk ,

      Eddy currents! How do they effect Electrical machines?

      Hi @cblair ,

       If the core is not laminated, eddy currents will cause a considerable loss in the cores of electrical machines which results in the excessive heating of the machine.
