Uniform magnetic properties in all directions for high-efficiency rotating machines—ideal for EV motors, compressors, generators, and industrial drives.
Non-Oriented Electrical Steel (also called Non-Oriented Silicon Steel or Cold Rolled Non-Oriented Electrical Steel) is a silicon steel designed for applications where the magnetic field rotates—such as electric motors, generators, compressors, and many industrial electrical machines. Unlike grain-oriented grades, non-oriented electrical steel provides uniform magnetic properties in all directions, which is essential for dynamic, high-speed rotating equipment.
✅ Designed for: Motors, Generators, Compressors, HVAC, EV Traction Systems
✅ Thickness:0.35 mm / 0.50 mm / 0.65 mm

⭐ Fast RFQ: Please send your thickness, width, grade target, coating type, quantity, and destination. We’ll reply with price & lead time.
It is mainly used in rotating electrical machines where the magnetic field rotates, such as motors, generators, compressors, pumps, HVAC equipment, and EV traction systems.
CRGO (grain-oriented) is optimized for magnetic flux in one direction and is used mostly for transformer cores. CRNGO/CRNO (non-oriented) provides uniform properties in all directions, making it ideal for motors and generators.
Common supply thicknesses include 0.35 mm, 0.50 mm, and 0.65 mm. If you need a different thickness or special tolerance, send an RFQ for confirmation.
Yes. We provide slitting, cutting, and multiple insulation coating options. We can recommend the best coating type based on your punching, stacking, and bonding process.
