Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
The utility model magnetic keeps magnetic circuit system, and whole magnetic circuit system comprises coil, sound iron core and permanent-magnet steel, and static iron core snaps in fixing in the hub of a spool hole (not movable part), and permanent-magnet steel connects with moving iron core forms armature component (moving part).
Further: coil rack is two group rectangular configuration, can require to select one of use, two or more coil serial or parallel connections to use according to product design.
Iron core is U-shaped, H shape, and coil stationary is on static iron core, and permanent-magnet steel is fixed on the moving iron core.
Permanent-magnet steel can be arranged in pairs or groups with U type or H sections core respectively, forms armature component, and processing mode is various.
Whole magnetic circuit system version is the reciprocal rectilinearly-movable structure of level, can make difformity according to designing requirement, sees also Fig. 2-9 (only being a part).
Concrete, as shown in Figure 2, static iron core 2 snaps in coil 1 centre bore fixing, the coil that adopts in Fig. 2 structure is that four small coils are composed in series, and it is longer to select for use the static iron core of two U-shapeds to snap in the pin of (this part is movable part) relative static iron core of loop construction in the centre bore of four small coil correspondences respectively; Permanent-magnet steel 4 is bumped into the center of the moving iron core 3 of H shape and forms H type armature component (this part is a moving part), and interior the cooperation with two static iron cores of centre bore that its four pin insert four small coil correspondences again respectively forms four working gas gaps (as shown in Figure 3).The rectangular member of coil both sides is moving iron core limiting component during rectilinear motion between two groups of coils.Permanent-magnet steel 4 produces two groups of parallel connections and the opposite permanent flux (air gap on left and right both sides is respectively a group) of direction at the sound iron core in four working gas gaps, when adding a pulse current for coil 1, it can form a ring seal magnetic circuit by the sound iron core, in four working gas gaps, produce the work magnetic flux, magnetic flux strengthens between permanent flux one group of air gap that direction is identical with it, magnetic flux between one group of air gap weakens in contrast, and moving iron core will move to the left or to the right in the effect of power.Coil is a flat structure, and volume is little, and power consumption is little; The sound iron core adopts direct punch process to form, and processing is simple, high conformity.
The electromagnetic principle that the magnetic circuit system of Fig. 4, Fig. 6, Fig. 8 adopts is respectively as Fig. 5, Fig. 7, shown in Figure 9, the electromagnetic principle basically identical that itself and Fig. 2 adopt just is processed into various difform according to requirements such as the shape of product design, volume size, contact forms.Among Fig. 4, static iron core adopts the structure of H shape, and its four pins snap in the small coil internal fixation respectively; The U-shaped armature component is formed in the be placed in center of the moving iron core of two U-shapeds of permanent-magnet steel, and four pin of two moving iron cores of U-shaped are same to be inserted in four small coils and to cooperate four working gas gaps of formation with H shape static iron core.Among Fig. 6, static iron core adopts the formation two "] that H shape is divided into two halves " structure, a small coil internal fixation respectively is inserted in the intermediate portion; Permanent-magnet steel is bumped into the center of the moving iron core of H shape and forms H type armature component, and its four pin cooperate four working gas gaps of formation again respectively with two static iron cores.Among Fig. 8, static iron core and moving iron core all adopt a U-shaped structure, two pins of U-shaped static iron core snap in two coil internal fixation, moving iron core centre position studs with permanent magnet, the interior cooperation with static iron core of centre bore that two pin inserts two small coil correspondences respectively forms two working gas gaps, the centre position, bottom of moving iron core also links to each other with a spring, and the other end of spring is a stiff end, is fixed on the base.
