Abstract
The utility model relates to a permanent magnetic rotator, which is mainly composed of a shaft, a tile-shaped permanent magnet, and a columnar magnetic yoke. The shaft is fixed on the magnetic yoke along the axle wire. The permanent magnet has two kinds: one has the technical proposal that the outer tiling face is N pole, and the other has the technical proposal that the tiling face is S pole. The two permanent magnets are alternatively arranged on the pillar face of the magnetic yoke. The utility model is characterized in that both sides of the permanent magnet are in the dovetail shape; depression bars made of non-magnetic conductive materials and matched with the lateral sides of the permanent magnets are arranged between the two permanent magnets, and the depression bars are fixedly arranged on the magnetic yoke by screws. The utility model has the advantages of firm fixation, and the permanent magnets can not drop when the rotor is in high speed.
Description
The utility model relates to the rotor that a kind of permanent magnet generator is used.
Existing p-m rotor mainly is made of axle, watt shape permanent magnet, column yoke, and axle is fixed on the yoke along the axis, and permanent magnet has two kinds, and a kind of outer tiling is the N utmost point, and another kind is the S utmost point, and two kinds of permanent magnets are bonded on the cylinder of yoke at interval.This kind p-m rotor is because permanent magnet is to be bonded on the yoke, and under the influence of environment (as high temperature), bonding agent can wear out ineffective around, and when the p-m rotor high speed rotating, permanent magnet can come off from yoke under action of centrifugal force.
Goal of the invention of the present utility model is to provide a kind of permanent magnet to be fixed in securely on the yoke, can be because of the aging p-m rotor that comes off of bonding agent.
The utility model is to realize like this, mainly constitute by axle, watt shape permanent magnet, column yoke, axle is fixed on the yoke along the axis, permanent magnet has two kinds, and a kind of outer tiling is the N utmost point, and another kind is the S utmost point, two kinds of permanent magnets place on the cylinder of yoke at interval, its special feature is that the both sides of permanent magnet are dovetail shaped, is provided with the press strip made from non-magnet material that matches with the permanent magnet side between two permanent magnets, and press strip is fixed on the yoke by screw.
The utility model compared with the prior art, have affixed firmly, the rotor advantage that permanent magnet also can not come off under high speed rotating.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross section view of Fig. 1.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail;
As shown in the figure, the utility model is mainly by axle 1, permanent magnet 5, yoke 4, yoke 4 is column, the axle 1 along the axis cross-under on yoke 4, permanent magnet 5 is a watt shape, permanent magnet 5 has two kinds, a kind of outer tiling is the N utmost point, another kind is the S utmost point, 5 one-tenth sides that are opposite to yoke 4 of two kinds of permanent magnets, and the both sides of permanent magnet 5 are dovetail shaped, 5 of two permanent magnets are provided with the press strip made from non-magnet material 3 that matches with the permanent magnet side, press strip 3 is fixed on the yoke 4 by screw 2, and like this, permanent magnet 5 just is fixed on the yoke 4 by press strip 3.Screw 2 can be made with non-magnet material.
Here, the permanent magnet 5 that is fixed on the yoke 4 can be 2 pairs, can be 3 pairs also can be 4 pairs or more than, like this, made p-m rotor can be 4 utmost points, can be 6 utmost points, can be 8 utmost points or more than.
