Description

technical field

[0001] The invention relates to the field of magnetic suspension bearings. The invented static test device for axial magnetic suspension bearings has a simple structure, is convenient to adjust, has a wide range of applications, and can carry out basic principles of magnetic suspension bearings, static characteristics of magnetic suspension bearings and product quality in the production process of magnetic suspension bearings. test. Background technique

[0002] Magnetic suspension bearings use magnetic field force to suspend the rotor. There is no mechanical contact between the rotor and the stator. It has the advantages of no friction, high allowable speed, no lubrication system, low noise, and small vibration. It is a new type of electromechanical bearing with broad development prospects. All-in-one product. In the design or production process of axial magnetic bearing, it is necessary to check the relationship between the magnetic field force and the app...
