Calculation method of a radial electromagnetic support of a turbomolecular vacuum pump

Magnetic bearings are increasingly used in various industries. Their unique features make them attractive for solving the problems of the rotor suspension and allow finding new approaches in the design of rotating machine components. Turbomolecular vacuum pumps (TMP) operate at high speeds of shaft and are used in high-vacuum systems, which confirms the relevance of the use of magnetic bearings in TMP. In this paper, the calculation method of the radial electromagnetic support of TMP, graphical dependences of the main bearing characteristics are presented.
