To keep leakage flux to be constant, the relation is analyzed between the air gap length and the non-magnetic material thickness with the rare earth magnet thickness under the air gap length variety.
在气隙长度发生变化时,为了保证漏磁大小不变,讨论了气隙与非导磁衬套厚度、磁钢厚度的关系。
The single core armored cable in the list are only suitable for use for DC circuit. If used for AC circuit, non-magnetic material or armored by reducing magnetic loss structure must be used.
