Cold Rolled Non Oriented Low Carbon Electrical Steel Product Description
Non-oriented electrical steel is mainly used as the iron core of large and medium-sized motors, generators, household motors and micro-motors, ballasts and small transformers. The main magnetic performance requirements of non-oriented electrical steel are low specific total loss and high magnetic polarization.
The low specific total loss can save a lot of electric energy and extend the working time of the motor. High magnetic polarization means that the magnetization ability is strong, the excitation current of the iron core is reduced, and the specific total loss and iron loss are reduced.
Cold Rolled Non Oriented Electrical Steel Key Characteristics
- Non-oriented Grains:
The steel's grains are randomly distributed, allowing for effective magnetization in all directions.
- Low Carbon Content:
Minimal carbon content is crucial for improving electrical resistivity, reducing magnetic aging, and minimizing energy losses.
- High Magnetic Permeability:
This property allows the material to be easily magnetized, enhancing its magnetic performance.
- Low Coercive Force:
A low coercive force means less magnetic energy is required to demagnetize the material.
- High Electrical Resistivity:
Silicon addition increases resistivity, significantly reducing eddy current losses.
CRGO Electrical Steel Applications
- Motors and Generators:
Its ability to perform well magnetically in any direction makes it ideal for the cores of electric motors and generators.
- Electrical Appliances:
Used in the magnetic components of various household and industrial appliances.
- Electrical Instruments:
Applied in the construction of the core materials for different electrical devices.
