Description

A kind of large bearing capacity high dynamic response axial direction Lorentz force magnetic bearing

Technical field

The present invention relates to a kind of non-contact magnetically suspension bearing more particularly to a kind of large bearing capacity high dynamic response axial direction long-range navigations Hereby power magnetic bearing.

Background technology

Precision stage has the advantages such as stability is good, operating accuracy is high, is to meet micro-lithography, digital control processing and surface shape The manufacture of the modern high ends such as looks detection and the base apparatus of high-precision measurement, have wide in fields such as aerospace, high-end equipment manufacturings Wealthy application space.Existing precise positioning work table can be divided into contact and contactless by support pattern, the former objective table It is supported by mechanical bearing, there are the advantages such as bearing capacity is big, but since there are contact wears, lead to non-linear serious, movement control Precision processed is relatively low, can not meet the technology requirement of high-end manufacture and high-precision measurement.The latter uses aerostatic bearing or hydraulic pressure more Bearing supports, and has many advantages, such as that motion control accuracy is high, stability is good, but complex structural designs, and processing and manufacturing required precision is high, The shortcomings of environmental requirement is high, occupied space is big, maintenance cost is high.Magnetic bearing can realize contactless suspension bearing, have structure letter It is single, environmental suitability is strong, can Vibration Active Control and the advantages that vibration suppression, be realize precise positioning work table contactless A kind of approach of suspension bearing.

By suspending power producing method, active magnetic bearings can be divided into reluctance force magnetic bearing and Lorentz force magnetic bearing.The former is logical It crosses and changes the size and Orientation of magnetic pole winding current to generate required control magnetic flux, so as to generate corresponding suspension bearing power, But its power is with electric current into quadratic relationship, and the linearized rear range of linearity is still relatively narrow, and control accuracy is low.The latter is positioned over by changing The size of current of winding and direction generate required suspension bearing power in stationary magnetic field, and power is linear with electric current, line Property degree it is good, control accuracy is high.Therefore Lorentz force magnetic bearing is more suitable for the high-precision suspension control of magnetic suspension precision workbench. Workbench is generally placed using axial load-bearing, and axial magnetic bearing should also have larger carrying while control accuracy is met Power, than radial direction magnetic bearing and deflection magnetic bearing requirement higher.A kind of outer rotor Lorentz forces of granted patent 201510146044.X Axial magnetic bearing, using two layers of loop construction, suspension bearing capacity is small, and magnet steel, magnet steel end magnetic circuit edge are placed in rotor unilateral side Effect is apparent, and leakage field is serious, flux density lack of homogeneity in air gap.In addition domain magnet steel size is big, need to use splicing construction, splicing seams Gap can cause flux density axially to fluctuate, and further reduced air gap flux density uniformity.To improve flux density uniformity in air gap, China is specially A kind of implicit Lorentz force magnetic bearing of 201710220579.6 Three Degree Of Freedom of profit and Chinese patent 201710220580.9 are a kind of double It deflects implicit Lorentz force deflection magnetic bearing magnet steel is located inside magnetic guiding loop, the paramagnetic contribution through magnetic guiding loop eliminates magnetic Flux density at steel splicing seams circumferentially fluctuates, while reduce pole end piece magnetic circuit edge effect, and it is uniform to improve flux density in air gap Property.Above-mentioned three kinds of scheme coils use single coil structure, and single coil provides suspending power, and power is bigger, and coil turn is more, Coil inductance is bigger, seriously constrains the high frequency dynamic response capability of bearing.
