磁性组件是指将永磁材料与不同种类的非磁性材料按照特定要求组装在一起，以实现特定应用功能的工具或系统。由于磁路的存在，磁性组件可以提供更强的吸力，或在特定空间内产生更强的磁场。
磁性组件的优点
提升机械强度
Inherently brittle is always a serious problem to the application of sintered Neodymium magnet, sintered Samarium Cobalt magnet, and sintered ferrite magnet. Repetitive mechanical shock will cause magnets to lose volume, thus lead to the certain deterioration in magnetic strength. Non-magnetic housing like ferrous metal, non-ferrous metal, or plastic protects the magnets from damage. Besides, non-magnetic material also contributes to a mechanically stronger magnetic system. The totally enclosed solutions like overmolding, ultrasonic welding, or laser welding, are technically feasible to fulfill harsh environmental requirements.
提升磁强度
除提升机械强度外，磁性组件最重要的功能是提升磁强度。
当磁体应用于磁性吸力件中时，吸力可达到单独使用时的数倍。对于海尔贝克阵列，其特定区域的磁通密度甚至可以超过阵列所使用永磁材料的剩磁。
Magnetic assemblies are able to generate much higher magnetic strength due to the flux conducting parts are normally an integral part of the entire magnetic circuit. Flux conducting parts can significantly increase the magnetic flux and guide it to the specific region. Moreover, magnetic assemblies also exhibit greater cost advantage under the same requirement of magnetic strength. Both pot magnet and Halbach array are the most persuasive products for this characteristic.
Mounting Mechanisms for Holding Applications
Non-magnetic parts in the magnetic assemblies typically possess mounting options for distinct holding applications.
SDM Magnetics specializes in the design and cost optimization of conventional magnetic assemblies by simulation and experience. Then demand for custom magnetic assemblies is growing steadily and this requires expertise in material choice and fabrication methods. SDM Magnetic is capable to produce all kinds of permanent magnetic materials, soft magnetic materials, and metal injection molding (MIM) parts and, more importantly, SDM Magnetics has been always pursuing integration capability of different materials to provide whole magnetic assembly solution to our customers. Besides industrial applications, SDM Magnetics is also keen to be involved in civilian magnetic assembly project.
