The hybrid magnet was made by combining electromagnet with permanent magnet(PM).
通过比较永久磁铁的不同安装位置的影响,给出混合磁铁的结构方案。
Starting from the two operational states of permanent magnet, this article explains that the working point of permanent magnet in the permanent magnet actuator is sited on the reversional curve, and the demagnetized curve of NFeB permanent magnet is approximately in a straight line,and its reversional curve coincides with the demagnetized curve, moreover,its flux density has repeatability.
从永久磁铁的两种工作状态出发 ,说明了永磁机构中永久磁铁的工作点位于回复线上 ,且钕铁硼永磁的祛磁曲线几乎是一条直线 ,它的回复曲线与祛磁曲线基本重合 ,磁感应强度具有重复性。
In this paper, an IBEM(Indirect Boundary Element Method) is presented for calculating permanent magnet field, and the formula of calculating magnetic field intensity is deduced.
