Non-Oriented Silicon Steel Coil H50W1300 H50W800 Electrical Steel Coil with 1200mm / 1220mm Width

1．Product Overview

Non-oriented silicon steel coils are cold rolled electrical steel products designed for motor cores, generators, compressors, and electrical equipment requiring stable magnetic properties in multiple directions. Grades such as H50W1300, H50W800, and H50W600 are commonly used for rotating electrical machinery where balanced magnetic performance and controlled core loss are required.

The material is processed through cold rolling and insulation coating technology to improve magnetic efficiency and reduce eddy current loss during operation.

2．Technical Solution

Non-oriented electrical steel contains silicon alloy elements that improve electrical resistivity and reduce magnetic core loss under alternating magnetic fields.

The coated surface layer helps provide insulation between laminations, reducing eddy current generation inside motor cores and transformer components.

Different core loss grades are selected according to efficiency targets and operating conditions:

• H50W1300 for standard industrial applications
• H50W800 for reduced core loss and improved efficiency
• H50W600 for higher efficiency motor systems
