NON ORIENTED ELECTRICAL STEEL SHEET, IRON CORE, MANUFACTURING METHOD OF IRON CORE, MOTOR, AND MANUFACTURING METHOD OF MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240013959 titled 'NON ORIENTED ELECTRICAL STEEL SHEET, IRON CORE, MANUFACTURING METHOD OF IRON CORE, MOTOR, AND MANUFACTURING METHOD OF MOTOR
Simplified Explanation
The abstract of the patent application describes a non-oriented electrical steel sheet with specific chemical composition, sheet thickness, average grain size, x1 value, e1 value, and iron loss.
- The sheet contains 1.0% or more and 5.0% or less of silicon (Si) by mass.
- The sheet thickness ranges from 0.10 mm to 0.35 mm.
- The average grain size is between 30 μm and 200 μm.
- The x1 value, calculated as (2b+b)/(3i), is less than 0.845.
- The e1 value, calculated as e/eis, is 0.930 or more.
- The iron loss (wis) is 80 W/kg or less.
Potential applications of this technology:
- Electrical transformers
- Electric motors
- Generators
- Inductors
- Magnetic cores for various electrical devices
Problems solved by this technology:
- Reduced iron loss in electrical steel sheets
- Improved magnetic properties
- Enhanced energy efficiency in electrical devices
Benefits of this technology:
- Lower energy consumption in electrical devices
- Improved performance and efficiency of electrical devices
- Cost savings in energy consumption
