Abstract

The bearing floats the rotating member on air, the parts being held from frictional contact by a magnetic field. The rotor 10 is a permanent magnet to which is secured a non-magnetic drive shaft 11. The lower end of the rotor is cone-shaped to fit the funnel-shaped upper end of the stator portion 12 of the bearing.

Magnetic Bearing

The bearing floats the rotating member on air, the parts being held from frictional contact by a magnetic field. The rotor 10 is a permanent magnet to which is secured a non-magnetic drive shaft 11. The lower end of the rotor is cone-shaped to fit the funnel-shaped upper end of the stator portion 12 of the bearing.

The stator 12 is also a permanent magnet having its poles opposing those of the rotor 10, The drive shaft 11 is freely mounted in a hole 14 in the stator portion. A driving source 15, secured to the end of shaft 11, drives the rotor 10. The two magnetic bodies 10 and 12 set up an opposing field on which the rotor floats free from contact with the stator.
