  Silicon steel sheet , also known as electrical steel, is a specialized low-carbon steel alloy infused with 1% to 5% silicon. Designed primarily for magnetic applications, it stands out as a cornerstone material in modern electrical engineering, thanks to its unique combination of high magnetic permeability, low core loss, and excellent magnetic induction—traits that make it ideal for guiding and amplifying magnetic fields with minimal energy waste. Broadly, silicon steel sheets fall into two main categories: grain-oriented (GO) and non-grain-oriented (NGO). Grain-oriented sheets have their crystal grains aligned in a single direction during manufacturing, maximizing magnetic permeability along that axis. This makes them perfect for static magnetic devices like power transformers, where magnetic fields flow in a fixed path. Non-grain-oriented sheets, by contrast, have randomly oriented grains, ensuring uniform magnetic performance in all directions—ideal for rotating...

  The lamination sheet EI series stands as a cornerstone component in modern electromagnetic devices, widely utilized in transformers, inductors, and electric motors. Named for its iconic “E” and “I” shaped steel sheets, this series is engineered to optimize magnetic performance while minimizing energy loss, making it indispensable in power electronics and electrical engineering. Structurally, the EI series consists of two complementary sheet types: the “E” sheet (with three prongs forming a rectangular frame) and the “I” sheet (a flat rectangular strip). When assembled, these sheets interlock to form a closed magnetic circuit— a design that reduces magnetic flux leakage significantly. This modular structure also simplifies production and maintenance: manufacturers can easily stack, align, and secure the sheets without complex machining, cutting down on assembly time and costs. Material-wise, most EI lamination sheets are crafted from silicon steel (also ...

  EI laminations are core components in transformers, motors, and inductors, playing a pivotal role in optimizing electromagnetic efficiency. Named for their alternating “E” and “I” shaped steel sheets, these laminations minimize energy loss while enhancing magnetic flux performance, making them indispensable in modern electrical systems. Constructed primarily from silicon steel (electrical steel), EI laminations leverage the material’s high magnetic permeability and low core loss. Silicon alloying reduces eddy current losses—circulating currents induced by alternating magnetic fields—by increasing electrical resistance. The thin sheets (typically 0.3 to 0.5 mm thick) are coated with insulating layers (e.g., oxide films or varnishes) to further suppress eddy currents between adjacent laminations. Manufacturing involves precision stamping of E and I shapes from steel coils, followed by annealing to relieve stress and refine grain structure, which improves ...
