Problems solved by technology

[0006] However, for this structure, due to the large distance between the axial position of the rotor detected by the axial sensor and the axial position of the thrust plate, the axial position of the rotor detected by the axial sensor is different from the actual position of the thrust bearing. The axial clearance data may be inconsistent, which will affect the control accuracy of the system, thereby reducing the working performance of the magnetic suspension bearing

Description

[0001] This application is a divisional application of a Chinese patent application submitted to the China Patent Office on "May 13, 2019" with the application number "201910395606.2" and the title of the invention is "Magnetic Suspension Bearing, Motor, Compressor and Air Conditioner". technical field [0002] The application belongs to the technical field of air conditioning, and in particular relates to a magnetic suspension bearing, a motor, a compressor and an air conditioner. Background technique [0003] Magnetic suspension bearings have the characteristics of no mechanical contact, no lubrication, high critical speed, long service life and high reliability, and are widely used in high-speed and ultra-high-speed fields. As an indispensable part of the magnetic levitation system, the sensor’s detection accuracy is very important. Improving the position detection accuracy of the magnetic levitation system can not only improve the overall performance of the system but als...
