Q: how normal can the stacking factor be

Stacking factor: the ratio of the cross-sectional area occupied by the magnetic alloy to the cross-sectional area of laminated or core components.

In short, the iron core of the motor is usually laminated by 0.5mm thick silicon steel sheets. Due to the insulating layer between the single sheets and the gap after lamination, the chip thickness will also change slightly during the lamination process. For example, when 50 0.5mm thick iron cores are stacked, the total thickness is 25mm, and the actual thickness is estimated to exceed 25mm. The ratio of these two thicknesses is the lamination coefficient. Generally, the lamination coefficient of cold-rolled silicon steel sheets is between 0.96 ~ 0.98. The normal requirements are b35a300 95%, b50a470 97%, and we can basically achieve more than 97%.
