about

Product Description

Ravi Electrical Stamping is a prominent manufacturer specializing in the production of E I Lamination, which is crucial for the construction of electrical machines such as motors, transformers, and generators. E I Lamination is made from high-grade electrical steel and plays a significant role in improving the efficiency and performance of electrical devices.

E I Lamination refers to thin, insulated sheets of electrical steel used in the construction of electrical transformers and motors. These laminations are stacked together to form the core of electrical machines. The name "E I" comes from the shape of the laminations, which are usually in the form of "E" or "I" shapes, commonly used for transformer cores or motor cores, respectively.

The base material is high-quality silicon steel, which has a high magnetic permeability and low core loss. The silicon content typically ranges from 0.5% to 3.5% to enhance electrical performance.

Key Features :

  • Electrical Steel: Made from high-quality silicon steel to reduce energy losses during magnetic flux.

  • Thin Sheets: Laminations are typically between 0.2 mm to 0.5 mm thick, reducing eddy current losses.

  • Insulation: Coated with an insulating layer to prevent electrical short circuits between layers of lamination.

  • Precision Cut: Precisely stamped for uniform thickness and dimensions to ensure proper performance in electrical machines.
