Why choose ultra-thin non-oriented electrical steel?
Nov 05, 2025
Today, with increasingly strict energy efficiency standards for motors and transformers, ultra-thin non-oriented electrical steel is becoming a key material for enhancing the performance of electromagnetic equipment. So, why are more and more engineers choosing this material?
Significantly reduce core loss
The greatest advantage of ultra-thin non-oriented electrical steel lies in its outstanding energy-saving capacity. As the thickness decreases (typically 0.10mm-0.25mm), the eddy current loss of the material in an alternating magnetic field significantly reduces. Especially in medium and high-frequency application scenarios, the iron loss can be reduced by 30% to 50%, which is crucial for improving the efficiency of the motor.
Enhance the efficiency and power density of motors
Modern motor design pursues higher power density and energy efficiency grades. Ultra-thin non-oriented electrical steel, with its excellent magnetic permeability and low loss characteristics, enables motors to achieve a smaller volume while maintaining the same output power, meeting the requirements of compact design.
Optimize high-frequency performance
With the development of power electronics technology, the driving frequency of motors is constantly increasing. Traditional silicon steel experiences a sharp increase in loss at high frequencies, while ultra-thin non-oriented electrical steel is specifically optimized for high-frequency applications and can maintain stable magnetic properties within the frequency range of 400Hz to 2000Hz.
Adapt to the demands of intelligent manufacturing
Ultra-thin non-oriented electrical steel features excellent stamping performance and surface quality, making it suitable for high-speed automated production. Its consistent material properties ensure the stability of motor performance in mass production, providing a reliable material basis for intelligent manufacturing.
Conclusion
Choosing ultra-thin non-oriented electrical steel is not merely about selecting a material; it is about choosing higher energy efficiency standards, more compact design solutions, and superior high-frequency performance. With the continuous improvement of energy-saving requirements, this material is bound to become the mainstream choice in the motor industry.
