Research of the Applicability of Magneto-Liquid Sealing of the Shaft of Regulated Electric Motors

The applicability of the magnetofluid sealing of the shafts of controlled electric motors with an increase in the rotational speed has been evaluated. A joint numerical simulation of the magnetic and hydrodynamic states of hermetic seals has been carried out. Their properties and characteristics are determined. Improved designs and control program for magnetic-liquid hermetic seals are proposed. An adaptive electrotechnical system of magnetic-liquid sealing of shafts of variable electric motors is described.
