无取向硅钢片（NO FeSi）的冲压和激光切割决定了切割边缘材料的变化，这对磁性能产生重要影响。通过冲压，它导致在切削刃附近区域的塑性变形。激光切割技术会产生热应力，这也会改变磁性。对于电机的生产来说，了解劣化的类型是非常重要的，因为总损耗会增加。试验钢为无FeSi牌号的M400- 65 A和M800- 65 A，面积为300 × 30 mm 2。用实验室单带测试仪在10 ~ 400 Hz的频率范围内，在1 T的峰值磁极化下测量了磁性。
Punching and laser cutting of non-oriented silicon iron sheets (NO FeSi) determine changes in the material at the cutting edge, which produce an important effect on the magnetic properties. Through punching it results a plastic deformation in the zone near the cutting edge. Laser cutting technology causes thermal stresses, which alter also the magnetic properties. The knowledge of the type of deterioration is very important for the production of the electrical machines, because of the increased total losses. There were tested steel samples of NO FeSi grades, M400-65A and M800-65A, with an area of 300 × 30 mm2. The magnetic properties were measured with a laboratory single strip tester in the range of frequency from 10 ÷ 400 Hz at 1 T peak magnetic polarization.
