Application Of Samarium Cobalt Magnets in Micromotors

The soft magnetic core materials used in micro-motors include samarium-cobalt magnets, electrical pure iron, iron-nickel alloys, iron-aluminum alloys, and soft ferrites.

The following is a brief introduction to the knowledge of samarium cobalt magnets:

Samarium-cobalt magnet is a samarium-cobalt alloy steel sheet magnet. It is a kind of soft magnetic material widely used in the manufacture of electrical equipment. It has many varieties, complete specifications and large consumption. According to different manufacturing processes, silicon steel sheets are divided into two categories: hot rolling and cold rolling. There are two types of cold rolling: isotropic (without orientation) and anisotropic (with orientation). The sheet thickness range is 0.05-1.0 mm, and 0.1-0.5 mm is commonly used in micro-motors. Before the 1970s, hot-rolled silicon steel sheets were mainly used at home and abroad. In recent years. Due to the superior performance of cold-rolled silicon steel sheet. Good technology, rapid development. Countries with advanced technology have eliminated hot-rolled silicon steel sheets. The production of cold-rolled sheets in my country has also developed rapidly. The output of DW and other series of cold-rolled non-oriented silicon steel sheets has increased year by year, and the scope of application has expanded.
