Description

A kind of implicit Lorentz force deflection magnetic bearing of the poly- magnetic effect of U-shaped

Technical field

The present invention relates to a kind of non-contact magnetically suspension bearing more particularly to a kind of implicit Lorentz forces of the poly- magnetic effect of U-shaped Deflect magnetic bearing.

Background technology

In such a way that electromagnetic force generates, active magnetic bearings can be divided into reluctance force magnetic bearing and Lorentz force magnetic bearing.The former By changing the size and Orientation of pole coil electric current, to change magnetomotive force, to change air-gap flux at magnetic pole, electromagnetism is controlled The size of suspending power, electromagnetic force and electric current it is square directly proportional, after linearized, the range of linearity is narrow, and control accuracy is low.The latter It is positioned over the size and Orientation of the energization winding current in stationary magnetic field by changing, generates required suspending power, power and electricity Flow directly proportional, the linearity is good, and control accuracy is high.Therefore, Lorentz force magnetic bearing be very suitable for having simultaneously gesture stability with it is quick The magnetically suspended gyroscope flywheel for feeling function, for deflecting suspension bearing.Under control model, high speed is forced using Lorentz force magnetic bearing Rotor shaft deflects, and exports precession control moment.Under sensitive mode, Lorentz force magnetic bearing compensated high-speed rotor is utilized Deflection disturbance torque, make it have good gyroscopic inertia, sensitive spacecraft attitude.

A kind of Large-torque magnetic suspension flywheel described in Chinese granted patent 201110253688.0 and paper《A kind of magnetic suspension Gyroscope flywheel conceptual design and Analysis on Key Technologies》The magnetically suspended gyroscope flywheel is all made of the external explicit long-range navigation of magnet steel Hereby power deflection magnetic bearings control rotor radial two-freedom deflection, air gap flux density is higher, but winding fringe region permanent magnetism leakage field is bright It is aobvious.To further increase winding area air gap flux density intensity, Chinese patent 201610920731.7 describes a kind of two-freedom The explicit Lorentz force deflection magnetic bearing of Halbach array enhances air-gap field using Halbach array magnetic steel structure scheme Intensity improves magnetic bearing deflection torque.The explicit Lorentz force magnetic bearing magnet steel of above two is respectively positioned on pole end piece, leads to gas Gap fringe magnetic leakage is apparent, i.e. magnetic circuit edge effect is notable, reduces the flux density uniformity.In addition, the radius of circle is larger where magnet steel, Domain magnet steel need to be spliced using polylith magnet steel, and the gap of stitching portion can cause flux density axially to fluctuate, and further reduced gas The uniformity of gap flux density.To improve air gap flux density uniformity, applies for a patent 201610597382.X and propose a kind of dual permanent-magnet Implicit Lorentz force deflects magnetic bearing, and magnet steel is built in inside magnetic guiding loop, magnet steel flux density wave because of caused by splicing is eliminated It is dynamic, but still there is apparent leakage field at pole edge, magnetic circuit edge effect is apparent.
