Non-oriented Silicon Steel

Non-oriented silicon steel is a special silicon steel material with excellent magnetic properties and low energy consumption. Non-oriented silicon steel is often composed of silicon, iron and a small amount of carbon, manganese, and other elements. It has high magnetic permeability and low hysteresis loss. , which has widespread applications in power transmission and conversion.

Silicon steel sheet performance indicators

• Low iron loss. The most important indicator of quality, countries around the world use iron loss value to classify grades. The lower the iron loss, the higher the grade and the higher the quality.
• High magnetic induction intensity. Silicon steel sheets can obtain higher magnetic induction under the same magnetic field. The size and weight of the motor or transformer core made with it are relatively small, which can save silicon steel sheets, copper wires and insulating materials.
• High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, and the stacking coefficient of the core is improved.
• Good film processing properties. This is even more important for manufacturing small and micro motor cores.
• The surface has good adhesion and weldability to the insulating film, which can prevent corrosion and improve film punching properties.
• The magnetic aging phenomenon is small. ·Silicon steel sheets must be delivered after annealing and pickling.

Application of Non-oriented Silicon Steel

• Energy Efficiency: NOES are primarily used in the cores of electrical motors, generators, and transformers. Their properties significantly influence the energy efficiency of these devices. For instance, steels with better magnetic properties (such as lower core losses and higher permeability) reduce energy wastage in the form of heat, thus improving the overall efficiency of electrical devices.
• Cost-Effectiveness: Compared to other materials used in similar applications, NOES offer a cost-effective solution without compromising on performance. This makes them a preferred choice in large-scale industrial applications where both cost and performance are critical considerations.
• Versatility and Performance: The non-oriented feature of these steels means that their magnetic properties are isotropic (equally good in all directions), which is advantageous in applications where the direction of magnetic flux is variable. This versatility makes NOES suitable for a wide range of electromagnetic applications, from large power transformers to small electric motors used in home appliances.
• Innovation in Electrical Mobility: NOES are increasingly important in the automotive industry, especially in the development of electric vehicles (EVs). High-performance NOES are essential for efficient, lightweight, and compact electric motors in EVs, directly impacting vehicle performance and range.
• Sustainability: With a growing focus on sustainable and green technologies, NOES are key to developing more energy-efficient electrical systems. Their improved performance contributes to the reduction of electrical losses and, consequently, a decrease in energy consumption and carbon emissions in various sectors.
