Abstract
The utility model relates to a permanent-magnet component for magnetic device, in particular to a permanent-magnet rod, which comprises permanent-magnet layers made of permanent-magnet material and magnetic conduction layers made of a plurality of magnetic conduction material, such as ingot iron, wherein the permanent-magnet layers and the magnetic conduction layers are laminated-fixed which reaches a shape of rod, two permanent-magnet layers are separated by one magnetic conduction layers, magnetic directions of two adjacent permanent-magnet layers are opposite or back-to-back. By realistic testing, the permanent-magnet rod surface magnetic induction intensity of the utility model can reach to 300 to 1500 millitesla which is higher than the conventional permanent-magnet rod.
Description
Technical field
The utility model relates to a kind of permanent magnetic part that is used for magnetic machine, particularly a kind of Permanentmagnet bar.
Background technology
In usefulness magnetic machines such as some magnetic plants, the surface induction intensity that improves its permanent magnetic part is to improve the important means of equipment performance.This type of uses employed Permanentmagnet bar parts in the magnetic machine at present, and its surface induction intensity generally only can reach 800~900 milli teslas, has limited the further raising of equipment performance.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of Permanentmagnet bar with novel magnetic structure is provided, and it compared with existing Permanentmagnet bar have higher surface induction intensity.
Permanentmagnet bar of the present utility model includes a plurality of magnetic layer and a plurality of magnetic layers of being made by permanent magnetic material of being made by permeability magnetic material (as Armco iron), magnetic layer and magnetic layer are stacked mutually fixing, constitute bar-shaped, its arrangement form is to be separated with one deck magnetic layer between between every two-layer magnetic layer, and the magnetic direction of simultaneously adjacent two-layer magnetic layer relatively or contrarily.It is fixing directly to bond between each magnetic layer and the magnetic layer; Also magnetic layer and magnetic layer can be placed in the non-magnetic sleeve, the sleeve closed at both ends is fixed; Can also open also at magnetic layer and magnetic layer center, fixing by the screw bolt and nut serial connection again.
Permanentmagnet bar of the present utility model is through actual test, and its surface induction intensity can reach 1300~1500 milli teslas, is much higher than existing Permanentmagnet bar.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the utility model;
Fig. 2 is the structural representation of second embodiment of the utility model;
Fig. 3 is the structural representation of the 3rd embodiment of the utility model.
Embodiment
As Fig. 1~shown in Figure 3, Permanentmagnet bar of the present utility model by a plurality of magnetic layers 1 and a plurality of magnetic layer 2 stack gradually be fixed into bar-shaped, alternating floor magnetic layer 2 between between every two-layer magnetic layer 1, the magnetic direction of adjacent two-layer magnetic layer be (direction of arrow among the figure is represented the magnetic direction of each magnetic layer) relatively or contrarily.Wherein, in the embodiment shown in fig. 1, directly bonding is fixing between each magnetic layer and the magnetic layer; In the embodiment shown in Figure 2, each magnetic layer 2 and magnetic layer 1 are placed in the non-magnetic sleeve 3, and the sleeve closed at both ends is fixed; In the embodiment shown in fig. 3, the center of each magnetic layer 2 and magnetic layer 1 has through hole, and they are fixing by pair of bolts 4 and nut 5 serial connections.
