Ultra-thin silicon steel (especially 0.1-0.2mm thick) is a core material for drive motors in new energy vehicles, and its technical level directly affects the efficiency, power density, and overall vehicle performance of the motor.

1. Improved energy efficiency: Generally speaking, the thinner the silicon steel sheet, the lower the eddy current loss. For example, reducing the thickness of the silicon steel sheet from 0.5mm to 0.1mm can reduce eddy current loss to 1/25 of the original. Therefore, new energy vehicle motors made of ultra-thin silicon steel can reduce energy waste and extend the driving range.

 

2. Power density: Thinner silicon steel allows motors to operate at higher speeds, thus increasing power density. For example, motors using 0.1mm ultra-thin silicon steel can reach speeds of up to 31,000 rpm. Motors made with ultra-thin silicon steel output more power in the same volume, or reduce motor size for the same power, contributing to vehicle weight reduction.

 

3.  Reduce iron loss: Iron loss is a key indicator for measuring the energy loss of silicon steel sheets. Ultra-thin silicon steel has a lower iron loss value, which can directly reduce the heat generation and energy waste during motor operation, and help improve output power and range.

 

Ultra-thin silicon steel is a crucial component in the performance race of new energy vehicles.

As material thickness continues to decrease to 0.1mm and below, the motors in new energy vehicles will become more powerful, efficient, and compact. The development of ultra-thin silicon steel continues, with a clear trend towards thinner, higher-performance (lower iron loss, higher strength) and broader applications (expanding from new energy vehicles to low-altitude aircraft, humanoid robots, etc.).

The key to improving the performance of drive motors in new energy vehicles lies in the continuous innovation of electrical silicon steel materials and coating technologies. As the core material of the motor stator core, the performance of low-iron-loss laminated silicon steel directly determines the motor's energy efficiency, power density, and range.

 

Thinning the steel sheet is one of the most effective technical approaches to reducing iron loss. Thinner silicon steel sheets can significantly reduce high-frequency eddy current losses and improve motor efficiency.

 

Low-iron-loss motor laminated silicon steel is indeed a key component in improving the energy efficiency of current motor technology. Through collaborative innovation in materials, processes, and design, it provides a solid foundation for the efficient, miniaturized, and low-noise operation of motors.

 

Low-iron-loss motor laminated silicon steel technology is directly driving energy efficiency upgrades in several key industries, such as new energy vehicle drive motors: this is currently the most cutting-edge area of  technology application. To achieve longer range and higher power density, new energy vehicle drive motors need to maintain low losses at high speeds. The use of ultra-thin silicon steel sheets has become a standard configuration for high-end motors.

 

In the future, technology will continue to evolve, moving towards thinner (e.g., 0.10mm and below), higher strength, and even integration with sensors to achieve intelligent status monitoring, providing continuous material support for the "dual carbon" goal.
