Title:
COMBINED SENSOR STRUCTURE FOR MAGNETIC BEARING
Document Type and Number:
WIPO Patent Application WO/2020/125104
Kind Code:
A1
Abstract:
Disclosed is a combined sensor structure for a magnetic bearing. The combined sensor structure comprises a rotor (1) and displacement sensors (3), wherein the tail end of the rotor (1) is provided with a boss portion (11), and an inner end face of the boss portion (11) is of a tapered face structure; and an even number of displacement sensors (3) are uniformly distributed in a circumferential direction of the rotor (1), and the displacement sensors (3) are located on one side of a tapered face in the boss portion (11). According to the combined sensor structure, a radial displacement sensor is omitted, such that the structure is simple, space is saved, the axial dimension of the rotor (1) is reduced, and the natural frequency of the rotor (1) is improved.
