The invention provides a magnetic suspension electromagnet unit. The magnetic suspension electromagnet unit comprises a magnetic suspension electromagnet winding, an iron core block and a quenched and tempered iron core. Impregnating varnish is impregnated in the magnetic suspension electromagnet winding, and the magnetic suspension electromagnet winding is sequentially wrapped with a pouring layer and a protective layer from inside to outside; an insulating layer or a pouring layer is arranged on the outer surface of the iron core block, and the iron core block is embedded into the quenched and tempered iron core to form a magnetic conductive rigid framework; and the magnetic suspension electromagnet winding is nested on the magnetic conductive rigid framework to form a magnetic suspension electromagnet unit. According to the magnetic suspension electromagnet unit provided by the invention, on the premise that the weight of parts is not increased, the magnetic conductance of the magnetic conductive material is better improved. The invention provides a packaging method of a magnetic suspension electromagnet. The packaging method comprises the steps of manufacturing a magnetic suspension electromagnet unit, dipping, pouring and spraying a protective layer. According to the magnetic suspension electromagnet packaging method, insulation and water resistance of the winding can be guaranteed at the same time, the heat dissipation capacity is improved, and the phenomena of cracking, stripping, bulging and the like of the pouring layer can be effectively reduced.
