According to the special working conditions of high-power motors, this paper designs a split magnetic liquid sealing device. The material is 316 austenitic stainless steel, which has good mechanical properties. In addition, the material contains Mo element, which has good corrosion resistance and high temperature resistance. It is suitable for use under harsh conditions and meets the special use conditions of high-power motors. In addition, the end cover also adopts a split structure. The design of the pole shoe also adopts a split structure, and a connecting hole is opened on it for the two parts of the split structure to be connected with hexagon socket head screws. The pole piece is a key component in the magnetic liquid sealing device. Its function is to form a magnetic circuit. The material is required to have high permeability and low coercivity.
