Electrical steel is special-purpose steel customized to obtain specific magnetic properties such as low core loss, small hysteresis area, and high permeability. Electrical steel is mostly produced in the form of cold-rolled strips that are less than 2 mm in thickness. These strips are cut into desired shapes, which are stacked together to form laminated cores of the transformer as well as the rotor and the stator of electric motors. The cut pieces of laminations can be finished by a punch ... Read more
