The present invention realizes like this, comprise the movable magnet member that is fixed on rotating shaft support end, be fixed on the fixed magnets member on bearing support, its specialization is that movable magnet member comprises the inner circle annular permanent-magnet body member being fixed by socket on rotating shaft support end, other three faces except outer side surface of inner circle annular permanent-magnet body member are provided with magnetic conduction armour iron, inner circle annular permanent-magnet body member by several piece side couple together surround annulus and base be that the permanent magnet blocks that the profile of magnetic pole is similar antiparallelogram shape is spliced, fixed magnets member comprises the cylindrical ring-type permanent magnet member being fixed on bearing support, other three faces except inner side surface of cylindrical ring-type permanent magnet member are provided with magnetic conduction armour iron, cylindrical ring-type permanent magnet member by several piece side couple together surround annulus and base be that the permanent magnet blocks that the profile of magnetic pole is similar antiparallelogram shape is spliced, cylindrical ring-type permanent magnet member is enclosed within outside inner circle annular permanent-magnet body member, the magnetic force direction of cylindrical ring-type permanent magnet member inner side surface is identical with the magnetic force direction of inner circle annular permanent-magnet body member outer side surface.
During use, circular permanent magnet member inner side surface with under identical repulsion magnetic force inner circle annular permanent-magnet body member outer side surface outside, realize maglev object, adopt armour iron, make cylindrical ring-type permanent magnet member except inner side surface and the inner circle annular permanent-magnet body member outside outer side surface form magnetic shielding outward, like this, except leading and focusing on the radial side of relative inner circle annular permanent-magnet body member radial side and outer ring-like permanent magnet member, magnetic force does not almost have outside divergence loss, make the magnetic force of radial side of inner circle annular permanent-magnet body member radial side and outer ring-like permanent magnet member strong, guaranteed to there is enough magnetic suspension forces.
Here, the outer side surface that the profile of formation inner circle annular permanent-magnet body member is the permanent magnet blocks of similar antiparallelogram shape is outer convex arc surface, the side that is the permanent magnet blocks of similar antiparallelogram shape by several piece profile that forms inner circle annular permanent-magnet body member couples together the rounded anchor ring of outer side surface of the annulus that surrounds annulus, the inner side surface that the profile of formation cylindrical ring-type permanent magnet member is the permanent magnet blocks of similar antiparallelogram shape is interior concaved circular cambered surface, the permanent magnet blocks side that is similar antiparallelogram shape by several piece profile that forms cylindrical ring-type permanent magnet member couples together the rounded anchor ring of inner side surface of the annulus that surrounds annulus.
Like this, inner circle annular permanent-magnet body member, the magnetic pole strength that cylindrical ring-type permanent magnet member is relative just can lean on very closely, effectively promote the repulsive force of magnetic force, to realize to greatest extent the effect of radial suspension.
The magnetic conduction armour iron outer side surface of the axial bi-side of inner circle annular permanent-magnet body member is provided with fixed base, fixed base is fixed on the magnetic conduction armour iron of cylindrical ring-type permanent magnet member outside, the inner side surface of two fixed bases is all fixed with fixed permanent magnet, the axial magnetic conduction armour iron outer side surface of the inner circle annular permanent-magnet body member of corresponding fixed permanent magnet is fixed with movable permanent magnet, and the magnetic force direction of the face that fixed permanent magnet is relative with movable permanent magnet is identical.
Like this, the inner circle annular permanent-magnet body member with armour iron just can stably be positioned on the position corresponding with cylindrical ring-type permanent magnet member.
The present invention compared with the prior art, have advantages of the space constraints of not being subject to, volume is little can realize radial suspension.
