本文提出了一种新的加热方法——“二次电流加热法”，以减少高效电机层压电工钢板铁芯上的铁损耗。众所周知，用于电机铁芯的电工钢板在电机制造过程中由于残余应力而使其磁性变差，从而不可避免地增加电机层压电工钢板铁芯的铁损。与传统方法相比，新提出的二次电流加热方法可以在很短的时间内提高层压电铁芯的磁性能，降低层压电铁芯的铁损。本文通过对该方法试样的电磁特性和加热特性进行验证，并将其应用于层合铁芯中，以减少铁的损耗。
This paper presents the newly proposed heating method named “secondary current heating method” to reduce the iron loss on laminated electrical steel sheet cores for high-efficiency electrical motors. It is well known that the magnetic properties of electrical steel sheets, which are used for electrical motor cores, are deteriorated by the residual stress during manufacturing of the electrical motors, and then the iron loss of the laminated electrical steel sheet cores of the electrical motors increases inevitably. The newly proposed secondary current heating method can improve the magnetic properties on laminated electrical steel sheet cores and reduce the iron loss of them in the very short time in comparison with conventional methods. In this paper, the electromagnetic and heating characteristics of the specimens by the proposed method were confirmed, and then it was applied into the laminated cores to reduce iron loss.
