阅读说明：本技术 一种叠片稀土永磁器件的制造方法 (Method for manufacturing laminated rare earth permanent magnet device ) 是由 段永利 邓文宇 齐丽君 张毅 孙昊天 于 2020-12-10 设计创作，主要内容包括：本发明公开了一种叠片稀土永磁器件的制造方法,包括：制备稀土永磁体；将两片以上的稀土永磁体沿稀土永磁体的磁场取向方向层叠排列；通过相邻两片稀土永磁体间涂覆的胶体粘接使其联结成叠片稀土永磁器件。在所述的叠片稀土永磁器件中,相邻两片稀土永磁体之间存在间隔膜层,且间隔膜层的厚度在300μm以下。所述的制造方法中包括在稀土永磁体预制件表面附着含有Tb元素的粉末或膜层的步骤,并对表面附着有粉末或膜层的稀土永磁体预制件进行真空热处理制成稀土永磁体。本发明采用叠片的结构形式制造渗铽效果优异的超厚磁体,同时还可以减小电机工作时在永磁器件内部产生的涡流损耗。(The invention discloses a method for manufacturing a laminated rare earth permanent magnet device, which comprises the following steps: preparing a rare earth permanent magnet; more than two pieces of rare earth permanent magnets are arranged in a laminated manner along the orientation direction of the magnetic field of the rare earth permanent magnets; the two adjacent rare earth permanent magnets are bonded by the colloid coated between the two adjacent rare earth permanent magnets to form the laminated rare earth permanent magnet device. In the laminated rare earth permanent magnet device, an interlayer membrane layer is arranged between two adjacent rare earth permanent magnets, and the thickness of the interlayer membrane layer is less than 300 mu m. The manufacturing method comprises the steps of attaching powder or a film layer containing Tb on the surface of the rare earth permanent magnet prefabricated member, and carrying out vacuum heat treatment on the rare earth permanent magnet prefabricated member with the powder or the film layer attached on the surface to manufacture the rare earth permanent magnet. The invention adopts the laminated structure form to manufacture the ultra-thick magnet with excellent terbium infiltration effect, and can reduce the eddy current loss generated in the permanent magnet device when the motor works.)
