Abstract

一种电磁感应器件，包括磁衣(110)和至少一组线圈(120)。磁衣(110)由全部磁单元拼合在一起形成，内部具有至少一个腔体。磁单元彼此之间的磁体分割面(AA)基本沿着磁通回路设置而不切断磁通回路。线圈(120)置于由磁衣(110)形成的腔体中，磁衣(110)中的磁通回路由线圈(120)通电后形成。磁衣(110)的整体结构包括至少两个导磁层(110'，110”)。上述电磁感应器件，一方面能够基本封闭以减少漏磁，另一方面由于磁单元上没有气隙，有效减小了磁阻。并且磁衣(110)采用层状结构，使得电磁感应器件能够以逐层叠加的方式进行制作，不仅降低了制作难度，也有助于获得形状扁平的高性能电磁感应器件。还提供了相应的电磁感应器件的制作方法。
