Description
Technical field
The present invention relates to a kind of non-contact magnetically suspension bearing, the sensitive implicitly spherical Lorentz force magnetic axis of especially a kind of control
It holds.
Background technique
Counteraction flyback, bias momentum wheel and the dual-purpose flywheel of attitude control energy storage are to change angle by changing the size of revolving speed
The size of momentum exports control moment, and torque accuracy is high, but torque is smaller, is not able to satisfy quick the urgent of excitement of spacecraft and is essential
It asks.Magnetically suspended gyroscope flywheel by deflect magnetic bearing force high speed rotor generate deflection, change rotor angular momentum direction, export into
Dynamic control moment, torque are big.In addition, using deflection magnetic bearing compensation deflection disturbance torque there is large inertia high speed rotor
Good gyroscopic inertia, sensitive spacecraft attitude.So deflection magnetic bearing is as one of magnetically suspended gyroscope flywheel core component, it is right
The attitude control precision of gyro and sensitive precision have great influence.The deflection torque of Lorentz force magnetic bearing is directly proportional to electric current, line
Property degree it is good, control precision is high, is commonly used for gyrorotor deflection and suspends control.
A kind of Large-torque magnetic suspension flywheel of Chinese patent 201110253688.0 and apply for a patent 201510813055.9 1
Lorentz force magnetic bearing described in kind internal rotor magnetic suspension spherical surface gyroscope flywheel is explicit (magnet steel is external) structure, magnet steel
Positioned at air gap two sides, end magnetic circuit edge effect is obvious, and leakage field is serious, and flux density uniformity is poor in air gap.In addition, domain magnet steel ruler
It is very little big, splicing construction need to be used, splicing gap can cause flux density circumferentially to fluctuate, further reduced air gap flux density uniformity.For
Flux density uniformity in air gap is proposed, a kind of dual permanent-magnet deflection Lorentz force magnetic bearing of Chinese patent 201610597382.X proposes
A kind of implicit Lorentz force magnetic bearing, magnet steel are located inside magnetic guiding loop, the paramagnetic contribution through magnetic guiding loop, eliminate magnet steel splicing
Flux density at seam circumferentially fluctuates, while reducing pole end piece magnetic circuit edge effect, improves flux density uniformity in air gap.It is above-mentioned
The stator of three kinds of Lorentz force magnetic bearing schemes is columned cup-shaped stator, and magnetic gap is that column is shelly-shaped, rotor deflection angle
Degree is smaller, and the output torque time is short, and maximum precession control moment is less than normal.For this purpose, 201510243920.0 one kind two of Chinese patent
Freedom degree Lorentz force outer rotor spherical surface magnetic bearing describes the explicit spherical Lorentz force magnetic bearing that a kind of air gap is spherical shell shape,
Improve rotor deflection angle.But program rotor uses individual pen magnetic steel structure, and air gap flux density is low, and suspension power consumption is big.To improve
Air gap flux density, a kind of trapezoid areas of Chinese patent 201610983437.0 deflect Lorentz force magnetic bearing and Chinese patent
Display spherical shape Lorentz force magnetic bearing described in a kind of 201510811186.3 outer rotor magnetic suspension taper spherical surface gyroscope flywheels is equal
Using double-round magnetic steel structure.In addition, magnet steel section be it is trapezoidal, reduce magnetic field edge effect, improve flux density uniformity.It is above-mentioned
The magnet steel of three kinds of explicit spherical Lorentz force magnetic bearings is located at air gap two sides, and end magnetic circuit edge effect is obvious, and leakage field is serious, gas
Flux density uniformity is poor in gap.The advantages of comprehensive implicit Lorentz force magnetic bearing and display spherical shape Lorentz force magnetic bearing, China is specially
A kind of double Halbach array spherical shape Lorentz force magnetic bearings of benefit 201610921211.8 describe a kind of implicit spherical Lorentz force
Magnetic bearing scheme eliminates magnet steel because of flux density fluctuation caused by splicing gap using magnetic guiding loop, it is uniform to improve flux density in air gap
Property, using Halbach array magnetic steel structure, enhance air-gap field intensity.The permanent magnetic circuit of above scheme is not optimized, magnetic flux
In magnetic conduction ring part, cloth uniformity is poor, and leading to magnetic circuit, sequentially effect is poor, reduces the uniformity of air gap flux density.Furthermore above-mentioned side
The stator of case uses single coil structure, and single coil should control rotor deflection, again sensitive attitude angle.Under control model,
Coil control electric current is larger, and sensitive mode lower coil Sensitive Current is very small, and Sensitive Current can be submerged in control electric current.Cause
Rotor cannot realize deflection control and angular-sensitive dual function simultaneously.
