Detailed description of the invention
nullFig. 2 ~ Fig. 4 show magnetic force balance-type switch magnetic linkage straight line motor structural representation one of the present utility model、Figure two、Figure three，Including bilateral secondary 1 be made up of the monolateral secondary of two face-to-face settings，Monolateral secondary is made up of grooved core，Bilateral secondary 1 coordinates composition double-flanged end switch magnetic linkage straight line motor with the bilateral primary being arranged between bilateral secondary 1，Bilateral primary is by the conducting magnet core 4 of least one set alternately attachment、Magnet 6 and winding 3 form，Adjustment of field excitation coil 5 is set on least one set conducting magnet core 4，Conducting magnet core 4 through has yoke portion H-shaped conducting magnet core 4 or without yoke portion II shape conducting magnet core 4 for bilateral，Excitation passage is cooperatively formed with corresponding bilateral secondary 1，Described adjustment of field excitation coil 5 is set on two through post lateral surface of H-shaped or II shape conducting magnet core 4，Described magnet 6 is arranged between adjacent two H-shaped or two through post lateral surface of II shape conducting magnet core 4，Described winding 3 is set on two through post medial surface of adjacent two H-shaped or II shape conducting magnet core 4.Wherein, Fig. 2, Fig. 3 use H-shaped conducting magnet core 4, Fig. 4 uses II shape conducting magnet core 4.
DC excitation path is as shown in Figure 3: adjustment of field excitation coil 5(is along normal direction) the adjacent adjustment of field excitation coil 5(of conducting magnet core I 7 air gap secondary iron core air gap conducting magnet core II 8 is along normal direction) air gap secondary iron core air gap conducting magnet core I 7 (returning to) adjustment of field excitation coil 5.Because of magnetic excitation circuit iron core through path and air gap 2 the most directly participate in energy converting between mechanical, not by magnet 6, therefore its excitation magnetic resistance is little, and adjustment of field excitation effect is much better than structure shown in Fig. 1.
The adjustment of field excitation coil 5 of described bilateral primary is positioned at groove I outside two through posts of H-shaped or II shape conducting magnet core 4, and as shown in Fig. 5, Fig. 6, Fig. 7, or adjustment of field excitation coil 5 stretches out conducting magnet core and is positioned at adjacent magnets groove II, as shown in Figure 8.4 liang of through posts of conducting magnet core or magnet 6 are equipped with adjustment of field excitation coil 5.
Described adjustment of field excitation coil 5 regulates unit as normal force or thrust.When as normal force regulation unit, detection side-play amount according to bilateral normal force or bilateral magnetic field or bilateral air gap 2 is passed through corresponding DC excitation electric current, the direction of exciting current and coil while being enhanced to the excitation field and normal force side making bilateral motor both sides, opposite side is weakened；When as thrust regulation unit, detection variable quantity according to load or merit angle or position or speed or load current is passed through corresponding exciting current, the direction of exciting current and being enhanced simultaneously around to the excitation field and normal force making bilateral motor both sides or be weakened simultaneously of coil；Bilateral primary coordinates with bilateral secondary 1 and constitutes magnetic force balance-type switch magnetic linkage straight line motor.
In above-described embodiment, the through post of described bilateral through conducting magnet core 4 can offer at least one groove near air gap 2 end face, and described field magnet 6 can use permanent magnet, or superconducting magnet, or electrical excitation body, depending on concrete needs.In general, the preferential strong magnetic permanent-magnet using NdFeB material to make.The normal direction height of magnet 6 is less than or equal to H-shaped or the normal direction height of II shape conducting magnet core 4.The bilateral primary lateral ends of above-mentioned magnetic force balance-type switch magnetic linkage straight line motor or yoke portion are linked into an integrated entity by connector, cooperatively form unified magnetic force balance-type switch magnetic linkage straight line motor with bilateral secondary 1.
Magnetic force balance-type switch magnetic linkage straight line motor described in the utility model, the ingenious construction features applying double-flanged end switch magnetic linkage straight line motor, it is provided with H-shaped or the bilateral through conducting magnet core 4 of II shape in primary, passage is provided for bilateral primary DC excitation magnetic circuit, magnetic resistance and leakage field are greatly reduced, while power density and thrust are significantly increased, adjustment of field excitation ability is obviously enhanced.Primary permanent magnet main magnetic circuit of the present utility model and DC excitation auxiliary magnetic circuit can reach almost Perfect in theory simultaneously, that is permanent magnet and adjustment of field excitation coil magnetic potential are little in the loss of primary inner region energy, nearly all for participating in primary and secondary energy converting between mechanical, this is unapproachable in normal tape adjustment of field excitation magneto, therefore, thrust can reach more than the 130% of regular tap magnetic linkage straight line motor.The emulation further uneven normal force being adjusted (being allowed to be zero) shows, in the case of thrust keeps constant or does not affects thrust, the normal force regulation causing air gap 5 imbalance is comparatively sensitive, required DC excitation power is little, play the effect of " one or two group very heavy ", and secondary can realize magnetic suspension operation without increasing any cost.Thus solve existing linear electric motors and exert oneself little, the bottleneck problem of the long-term engineering constraint application such as regulating power is low, cost is high, volume is big, it is provided that the magnetic force balance-type switch magnetic linkage straight line motor that a kind of simple in construction, thrust are big, regulating power is strong, cost performance is high.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain at protection domain of the present utility model.
