Manufacturing process of laminated iron core

Manufacturing process of laminated iron core

Punching: The raw material of silicon steel sheets is punched into the required shape and size by punching machines and other equipment. The accuracy of punching has a significant impact on the performance and quality of the iron core.

Stacking: The punched silicon steel sheets are stacked in a certain order and manner, usually using mechanical pressure or hydraulic methods to ensure the tightness and neatness of the stacked sheets. During the lamination process, it is necessary to control the pressure and dimensional accuracy of the laminations to ensure the performance of the iron core.

Insulation treatment: In order to reduce eddy current losses, the surface of silicon steel sheets is usually subjected to insulation treatment, such as coating with insulation paint or using other insulation processes. The quality of insulation treatment directly affects the insulation performance and loss characteristics of the iron core
