Eddy currents are small circulating currents induced in the core material when it is exposed to changing magnetic fields. In electrical devices like transformers and motors, eddy currents result in energy losses and heat generation, reducing the efficiency of the device. By using thin laminations of NGO silicon steel, the continuous electrical path for eddy currents is interrupted at each interface between the laminations. This “laminating” effect significantly reduces eddy current losses.Each lamination in an NGO silicon steel core is electrically insulated from its adjacent laminations using a layer of insulating varnish or oxide coating. This ensures that eddy currents cannot flow freely across the laminations and further reduces energy losses.The laminations are stacked together to form the core, and they are held together with the help of mechanical pressure or by using binding materials. The stack of laminations creates an efficient magnetic path for the magnetic flux, allowing for effective energy transfer.
