Description
Technical field
The present invention relates to a kind of annular winding segmented permanent magnet synchronous linear motor, belong to the techniques of linear motor field.
Background technology
From the nineties in last century, follow with the neodymium iron boron fast development of the permanent magnetic material technology that is representative, permanent synchronous linear electric motor (PMLSM) is with its superiority at aspects such as thrust, dynamic property, positioning accuracies, and becomes the first-selected driver part of linear servo system gradually.Application scenario in the high-thrust long-stroke demand, advance accelerating system, promote transportation system etc. as big load, long elementary dual-side flat plate type permanent magnetic linear synchronous motor is bigger owing to having instantaneous thrust, reliable, the advantages such as influence of not having tangential normal force, become a kind of important power source, cause that people more and more pay attention to.But the elementary motor of this length if the elementary stator of big current drives is carried out whole section power supply, can cause the energy to waste greatly, and the inductance of whole armature winding is bigger, can increase the difficulty and the cost of control.Therefore, the armature winding of long preliminary linear motor adopts segmentation structure usually, and the existing method that generally adopts both at home and abroad is: the elementary stator of motor is carried out segmentation, and making stator is discontinuous stator, shown in Figure of description 5.On support 4, first armature core 1 and second armature core 11 segment distance of being separated by arranges among Fig. 5, and mover is art skating when moving at interval 3 places.This mode, because the mover that causes when the end effect of linear electric motors itself and mover art skating and the change of stator coupling area, make electric mover when the operation of 3 places, interval of first armature core 1 and second armature core 11, produce bigger force oscillation, have a strong impact on the whole system reliability of operation.
Summary of the invention
The purpose of this invention is to provide a kind of annular winding segmented permanent magnet synchronous linear motor, it is big that it has solved existing segment permanent magnet synchronous linear motor force oscillation, the problem of system's operational reliability difference.
The present invention includes primary and secondary, secondaryly comprise two permanent magnet excitation parts, two permanent magnet excitation parts lay respectively on the elementary upper surface and lower surface, be provided with air gap between the inner surface of permanent magnet excitation parts and the secondary upper surface, be provided with down air gap between the inner surface of another permanent magnet excitation parts and the secondary lower surface; The structure of described two permanent magnet excitation parts is the mirror image symmetry;
Described elementaryly form by multistage armature core and a plurality of annular armature winding, the multistage armature core is close proximity in turn, twine an annular armature winding on the outer surface of every section armature core respectively, the integer groove winding of each annular armature winding for connecting to form in turn by a plurality of individual layer loop coils; The toroidal coil plane of described individual layer is vertical with the secondary direction of motion;
Described each permanent magnet excitation parts are by mover iron yoke and many flat permanent magnet body is formed, on many inner surfaces that the flat permanent magnet body are fixed in mover iron yoke, many flat permanent magnet body is arranged by single file multiple row formula in the inner surface upper edge of the mover iron yoke direction of motion; The magnetizing direction of flat permanent magnet body is perpendicular to mover iron yoke, and the magnetizing direction of adjacent panels shape permanent magnet is opposite; The magnetizing direction of relative two the flat permanent magnet bodies in position is opposite on two permanent magnet excitation parts.
Advantage of the present invention is: bilateral structure annular winding segmented permanent magnet synchronous linear motor of the present invention, secondary two limits with elementary between the direction of the normal force that forms opposite, can cancel out each other, can satisfy the demand of big load propelled at high velocity system instantaneous high thrust; The segmentation method of the armature core that adopts makes adjacent armature core close proximity, and different annular armature winding disconnect on circuit, and in the process of whole motor operation, electric motor primary, secondary coupling area remain constant like this.Compare with now general elementary segmentation method, there is not the interval between the adjacent armature core section, and the interval that does not have the space between two adjacent annular armature windings, when certain section of motor secondary turnover primary electrical armature core, can not produce big fluctuation and noise because of tangible in-out end effect; Can not cause bigger thrust to fall, make whole system stable because of the reducing of its coupling area.Simultaneously can reduce energy resource consumption, improve system effectiveness.
