切割电工钢片以形成定子和转子的形状会影响片材的磁性能。磁损耗的增加和磁导率的下降都会对电气设备的设计产生影响。本文研究了这种劣化对高速永磁同步电机定子优化设计的影响。基于对放大的爱泼斯坦框架上不同宽度的钢板带材的测量，从现象学的角度分析了冲压造成的劣化。损失的计算采用贝尔托蒂模型，该模型的系数取决于板材的宽度。利用该模型对一台同步电机进行了优化设计。
Cutting the electrical steel sheets to form the shape of the stator and the rotor affects the magnetic properties of the sheets. The increase of the magnetic losses as well as the drop of the magnetic permeability can impact on the design of electrical devices. This paper investigates this deterioration effect on the optimal design of the stator of a high-speed permanent magnet synchronous motor. The deterioration due to punching is phenomenologically analyzed based on measurement of strips of steel sheets with various widths on an enlarged Epstein frame. The losses are computed with a Bertotti model whose coefficients depend on the width of the sheets. The optimization of a synchronous machine is then carried out with this magnetic losses model.
