GNEE New Material Rolled Silicon Steel

Rolled non-oriented electrical steel is also called cold-rolled non-oriented electrical steel.NOES is sometimes referred to as cold-rolled non-oriented (CRNO), non-grain oriented (NGO), non-oriented (NO), or cold-rolled non-grain oriented (CRNGO) electrical steel. These terms are interchangeable.

Non-oriented electrical steel, commonly known as non-grain-oriented electrical steel or non-oriented silicon steel, is a crucial material in the manufacturing of electrical components, such as transformers, motors, and generators.

Lamination and Insulation:

Laminated Construction: Non-oriented electrical steel is often provided in the form of thin laminations, which are stacked together to form the core. The laminations are insulated from each other to minimize eddy current losses.

Thickness and Coatings:

Various Thicknesses: Non-oriented electrical steel is available in various thicknesses to suit different applications and design requirements.

Surface Coatings: In some cases, the material may have coatings or surface treatments to enhance its performance or protect it from environmental factors.

Cold Rolled Electrical Steel

In order to reduce the energy loss of the motor, the application of high-efficiency non-oriented electrical steel plates and the optimization of the lamination process are important factors. Motor core loss deterioration is affected by multiple factors such as flux distribution, stress and strain, spatial harmonics, temperature and short circuits between laminations. In traditional clamping methods, steel plates are usually stacked by interlocking or welding. The measured welding energy loss is much greater than the interlocking energy loss. Therefore, interlocking is well known and commonly adopted, with the advantage of easy conduction. The shape of the protrusion affects the fastening strength.
