Abstract
The utility model relates to a single-magnetic circuit permanent electromagnet with single coil, which comprises a static bottom core (1), a magnetizing coil (2), a coil frame (8), a static middle core (5), a permanent magnet (3) and a dynamic core (7). The utility model is characterized in that the permanent magnet (3) is embedded in a circular space formed by the static bottom core (1) and the static middle core (5); a fixed air gap (4) is arranged between the static bottom core (1) and the static middle core (5) in the circle of the permanent magnet (3); the central lines of the permanent magnet (3) and the fixed air gap (4) locate in the axes of the same level; the magnetizing coil (2) is assembled to the outside of the poles of the static middle core (5). Compared with prior permanent electromagnet, the utility model has the advantages of compact structure, convenience for assembly, small current for coil controlling and fast speed for electromagnetic force change. A magnetic path is formed for a reverse magnetizing coil by connecting the permanent magnet (3) and the fixed air gap (4) in parallel, which avoids magnetic fading for the permanent magnet to insure the permanent magnet to work safely and reliably.
Description
Technical field
The utility model relates to a kind of permanent magnet solenoid that adopts unicoil control.Particularly relate to the single magnetic circuit work of a kind of employing, the permanent magnet solenoid of the two-way control of unicoil.
Background technology
Present existing electromagnet mainly is made up of dynamic and static iron core and coil.Coil electricity, moving iron core adhesive, coil blackout, moving iron core discharges.Owing to will keep the long-term energising of moving iron core adhesive needs, so novel permanent magnet solenoid is developed.Cooperating the permanent magnet solenoid of device for switching at present is twin coil, two magnetic route structure form.Though the permanent magnet solenoid of this structure can be realized coil moment energising control, the purpose that permanent magnetism keeps, but owing to must be the suction that coil electricity and the power that produces in the air gaps magnetic circuit produce at small air gap greater than permanent magnetism, electromagnet ability operate as normal, so, Control current is bigger, is difficult to satisfy the real work needs.Simultaneously, cause control loop components and parts power bigger, volume is bigger, and cost is higher.
Summary of the invention
The purpose of this utility model is the defective that exists in the above-mentioned prior art, a kind of permanent magnet solenoid of new structure is provided, adopt unicoil, single magnetic Circuit Design, the implementation structure compactness, easy for installation, reliable, the coil Control current is little, the electromagnetic force pace of change is fast, has higher responsiveness.
The purpose of this utility model is achieved in that and comprises by quiet floor iron core, iron core in quiet, permanent magnet, coil, coil rack, moving iron core is formed, it is characterized in that, permanent magnet is inlaid in by in the annular space that is combined to form between quiet floor iron core and quiet middle iron core, and being between interior quiet floor iron core of permanent magnet annular and the quiet middle iron core has a fixedly air gap, and magnetizing coil is contained in quiet middle iron core periphery.Above-mentioned permanent magnet and fixedly the center line of air gap on same horizontal axis.Magnetizing coil is fixed on the quiet middle core magnetic pole outer, the bolt that quiet middle iron core and quiet floor iron core are made by nonmagnetic substance in the center.
Compare with existing permanent magnet solenoid, tangible advantage of the utility model and effect be, has compact conformation, and easy for installation, reliable, the coil Control current is little, and the electromagnetic force pace of change is fast, characteristics such as quick action.

The utility model shown in Figure 1 is by quiet floor iron core 1, magnetizing coil 2, and permanent magnet 3, fixedly air gap 4, quiet middle iron core 5, air gap 6, moving iron core 7, coil rack 8, bolt 9 constitutes.
Embodiment
Illustrate an embodiment of the present utility model below in conjunction with accompanying drawing 1,2,3:
This product is an axially symmetric structure, and coil turn is 1350 circles, is wrapped in to constitute magnetizing coil 2 on the coil rack 8, is fixed on the magnetic pole outer of quiet middle iron core 5.Annular permanent magnet 3 be inlaid in quiet floor iron core 1 and quiet in the annular space that is combined to form of iron core 5, the quiet floor iron core 1 in the middle of the interior ring of permanent magnet 3 and quiet in a fixedly air gap 4 is arranged between the iron core 5; Permanent magnet 3 and fixedly the centerline of air gap 4 on same horizontal axis.Quiet floor iron core 1 with quiet in iron core 5 is connected by being in the bolt 9 that the locational nonmagnetic substance in axis makes, simultaneously with permanent magnet 3, the magnetizing coil 2 and fixedly pad in the air gap 4 is spacing, fixing, the main body of formation permanent magnet solenoid.The moment energising of coil forward, moving iron-core element 7 are produced suction by permanent magnet 3 behind the coil blackout and keep (concrete the action of a magnetic field situation as shown in Figure 2) by the permanent magnet solenoid adhesive; When the reverse moments energising of coil 2, moving iron core 7 and quiet floor iron core 1 and quiet in form suction in the air gap 6 of 5 of iron cores and be about zero, moving iron core 7 is (specifically the action of a magnetic field is as shown in Figure 3) separately, thus realization electromagnet repertoire.
The utility model is that reverse magnetizing coil forms magnetic circuit at permanent magnet 3 fixedly air gaps 4 in parallel, can not produce the magnetic of dispelling to permanent magnet, guarantees the safe and reliable work of permanent magnet.
