Sheet, iron material made into sheets. It is obtained by passing thick plates between rollers, that is, by rolling. These sheets with different thicknesses are cut within certain standard sizes or in strips. Besides the covers of various wheeled vehicles, ship hulls and many technological application areas, one of the most important usage areas of sheet metal is electrical vehicles. The core of the rotor, stator windings and transformer windings of the electric motors consists of silicon sheet bundles. The most important feature of siliceous sheets is that they minimize magnetic losses and increase efficiency, thanks to the silicon they contain. In addition, this silica added to the iron makes the iron more stable by reducing the changes that may occur in the magnetic properties of the iron over time. The orientation of the sheet crystals in a certain direction during rolling causes the quality of the sheet to increase in terms of magnetic properties and requires less sheet metal for a specific magnetic circuit.
