Title: Magnetic Balancing of Bearings
IPC: G01F15/00
Filed: 1980-04-22
Abstract: A vertical axis turbine rotor 11, intended particularly for measuring low gas flows, is mounted on a fairing 15 through low friction bearing 19 on a stationary spindle, and an upper pair of magnets 22, 20 having facing south poles are secured one to the rotor and the other to the fairlng and a similarly secured lower pair of magnets 21, 23 have facing north poles. The rotor, having a limited freedom to move up and down on the spindle, tends to move to a position in which the various vertical forces, e.g. its weight, the repelling forces between the magnets and upward thrust from flowing gas, cancel one another out. This reduces the pressure on the bearing and thereby the frictional resistance to rotation. <IMAGE>
