SIMPLIFIED RADIAL MAGNETIC BEARING

摘要

The design and arrangement of a magnetic bearing (1) for use in rotary machines is disclosed. The magnetic bearing contains magnets (8, 26, 27) circumferentially spaced about the axis of rotation of a shaft (35) and supports the shaft (3) while allowing rotation of the shaft within the bearing (1). The magnetic bearing (1) is characterized by having at least one sector of the bearing (8) applying a steady force to the shaft (35) and at least two controllable sectors (26, 27) providing a modulated force to the shaft (35).
