As the core material of power equipment, silicon steel sheet is widely used in transformers, motors and other fields. Its processing quality directly affects energy efficiency and equipment life. Traditional mechanical stamping is prone to burrs and stress deformation, resulting in a decrease in magnetic properties. Laser cutting technology, with its non-contact and high-precision characteristics, provides a new path for high efficiency and low loss for silicon steel sheet processing, promoting the transformation of the power industry to refined manufacturing.

 

Laser cutting achieves micron-level incisions by focusing the beam, avoiding mechanical stress from damaging the lattice structure of silicon steel sheets, and maintaining the high magnetic permeability and low iron loss characteristics of the material. For example, motor manufacturers use fiber laser technology to cut ultra-thin silicon steel sheets, with smooth incisions and no deformation, significantly reducing eddy current losses during motor operation and improving energy efficiency levels.

 

The stator and rotor of the motor need to stack silicon steel sheets into precision components, and traditional processes are difficult to ensure the consistency of the size of each layer. Laser cutting can programmatically process special-shaped holes and curved contours, complete multi-piece synchronous cutting in a single positioning, and the stacking accuracy reaches the micron level, which increases production efficiency several times compared to traditional methods while reducing material waste.

 

The demand for ultra-thin silicon steel sheets in the new energy sector has surged, and mechanical processing can easily lead to curling or breaking. Laser cutting uses dynamic focusing technology to achieve stable processing of ultra-thin materials, with no burrs on the edges and no need for secondary processing. It is especially suitable for the precision manufacturing of micro motors and high-frequency transformers.

 

Laser processing does not require molds, reduces changeover time and consumables costs, and is oil-free, which is in line with the trend of low-carbon production. While the utilization rate of silicon steel sheets is improved, the frequency of equipment maintenance is reduced, and the overall cost is significantly optimized.

 

With the advantages of "zero contact and high flexibility", laser cutting technology breaks the bottleneck of silicon steel sheet processing and helps power equipment upgrade energy efficiency and green transformation. In the future, with the deep integration of intelligent control and laser technology, silicon steel sheet processing will move towards a new stage of intelligent manufacturing with higher precision and lower loss.
