Description

A kind of implicit Lorentz force deflection magnetic bearing of double deflection

Technical field

The present invention relates to a kind of non-contact magnetically suspension bearings more particularly to a kind of implicit Lorentz force of double deflection to deflect magnetic axis It holds.

Background technique

Attitude control system is the important subsystem of spacecraft, and attitude control accuracy directly affects the performance of spacecraft. With the development of space technology, requirement of the spacecraft to attitude control system is higher and higher, especially to volume, weight, the service life, Reliability, functional integration etc. have increasingly harsher requirement.Overwhelming majority spacecraft attitude control system is still adopted at present It is used as the executing agency of attitude system with mechanical flywheel.It inherently rubs since mechanical flywheel exists, needs to lubricate, not can be carried out master It the defects of dynamic vibration control, fundamentally limits flywheel performance and further increases.Magnetically levitated flywheel is that inertia of new generation executes Mechanism eliminates the fretting wear of mechanical bearing, reduces flywheel unbalance mass, and draw due to using magnetic suspension bearing technology Rise vibration, improve flywheel output torque precision and service life, be high score earth observation satellite ideal inertia execute machine Structure.Since magnetically levitated flywheel eliminates the zero passage friction of mechanical bearing, have mechanical flywheel can not under reaction operating mode Comparable advantage.Under high speed offset operation mode, magnetic bearing has the function of to carry out flywheel rotor Vibration Active Control and to defending The function of star platform progress vibration suppression.Revolving speed is further increased, makes flywheel that there is biggish kinetic energy, by changing Speed of Reaction Wheels Size is mutually converted kinetic energy with electric energy, is realized two functions of attitude control and energy storage of flywheel, is used as attitude control energy storage two Use flywheel.Since magnetically levitated flywheel rotor is the suspension bearing in certain magnetic gap, flywheel rotary shaft can be in certain angle It is deflected back and forth in range, biggish gyroscopic couple can be exported moment, micro- gimbaled flywheel is used as, further increases deflection angle Also act as high-torque flywheel (universal flywheel).The disturbance torque that the translation suspension of three axis suspends to radial deflection is eliminated, high speed is made The flywheel rotor of rotation is provided simultaneously with the function of posture sensitivity and gesture stability, is used as gyroscope flywheel.Under torque mode, benefit It forces high speed rotor that precession occurs with deflection magnetic bearing, exports moment high-torque；Under sensitive mode, compensated using deflection magnetic bearing Radial twisting disturbance torque, makes rotor have good gyroscopic inertia.

The electromagnetic force that Lorentz force magnetic bearing generates is directly proportional to electric current, and the linearity is good, and control precision is high, is very suitable to magnetic Suspending gyrorotor flywheel, for radial two-freedom high-precision deflection control.Paper " a kind of magnetically suspended gyroscope flywheel conceptual design with Analysis on Key Technologies " described in magnetically suspended gyroscope flywheel, realized using a Three Degree Of Freedom Lorentz force magnetic bearing axial flat Dynamic and radial two-freedom deflection control, but its axial winding and deflection winding are radially placed in same air gap, and air gap is wide Degree one is fixed, and the total number of turns of axial winding and deflection winding is certain, therefore two kinds of umber of turns are less, causes magnetic bearing axial flat Dynamic suspension stiffness and deflection stiffness are relatively low.A kind of Large-torque magnetic suspension flywheel of granted patent 201110253688.0 is using deflection Lip river The deflection of Lun Zili magnetic bearings control rotor radial two-freedom, width of air gap one are fixed, increase winding coil the number of turns, improve Lorentz force magnetic bearing deflection torque rigidity, but its magnet steel is located at pole end piece, and air gap fringe magnetic leakage is obvious, and it is equal to reduce flux density Evenness.In addition, the radius of circle is larger where magnet steel, domain magnet steel need to be spliced using muti-piece magnet steel, and splicing gap can cause Flux density circumferentially fluctuates, and further reduced air gap flux density uniformity.A kind of dual permanent-magnet of Chinese patent 201610597382.X is inclined Turn Lorentz force magnetic bearing, magnet steel is built in upper and lower magnetic guiding loop, reduce magnet steel edge effect, eliminates splicing gap The fluctuation of caused flux density, but farther out and circle number is less from winding due to magnet steel, cause air gap flux density smaller, deflection stiffness is relatively low.
