Abstract
The utility model relates to a permanent magnet motor rotor, which comprises a shaft, a columnar magnetic yoke arranged on the shaft and a tile-shaped permanent magnet which is arranged on the columnar magnetic yoke, wherein, the tile-shaped permanent magnet is adjacent to a permanent magnet with the characteristic that the excircle face is an S pole, the tile-shaped permanent magnet and the permanent magnet are evenly distributed on the outer column face, and the excircle face of the tile-shaped permanent magnet is an N pole. The utility model is characterized in that both end faces of the magnetic yoke are provided with end plates made of non-magnetic materials, one end face of the end plates is provided with flanges which have the same number as permanent magnets, the two end plates are fixed on the both ends of the magnetic yoke, and the tile-shaped permanent magnet is impacted and fixed on the magnetic yoke via the flanges on the end plates. The utility model has the advantages of simple manufacturing technique and low manufacturing cost; the permanent magnets can be firmly fixed on the excircle of the magnetic yoke.
Description
Technical field:
The utility model relates to a kind of rotor, particularly a kind of permanent magnet machine rotor.
Background technology:
The structure of the p-m rotor that watt shape permanent magnet is formed mainly is made of axle, watt shape permanent magnet, column yoke, and axle is fixed on the yoke along the axis, and a watt shape permanent magnet generally adopts adhesive method to be fixed on the cylindrical of yoke.After the long-time use of this kind p-m rotor, binding agent can wear out and ineffective, and when the p-m rotor high speed rotating, permanent magnet easily comes off under action of centrifugal force.
Chinese patent 99245755.6 discloses a kind of p-m rotor, this p-m rotor is that dovetail shaped is processed in watt shape permanent magnet both sides, be provided with the press strip made from non-magnet material between the permanent magnet both sides, press strip is fastened on the yoke cylindrical with screw, utilizes the press strip both sides that permanent magnet is compressed.Though this technology has solved the caducous problem of permanent magnet, more for a long time, just need a lot of screw of processing on the yoke cylindrical at the motor electrode logarithm, use more screw, obviously, processing technology complexity, manufacturing expense height.
Summary of the invention:
Goal of the invention of the present utility model is to provide that a kind of manufacturing process is simple, manufacturing expense is low, the permanent magnetism physical efficiency is securely fixed in the p-m rotor on the yoke cylindrical.
The utility model is to realize like this, comprise axle, be arranged on column yoke on the axle, be arranged on watt shape permanent magnet on the column yoke, watt shape permanent magnet periphery is that the N utmost point and periphery are that the permanent magnet of the S utmost point is adjacent and be evenly distributed on the yoke external cylindrical surface, its special feature is that the yoke both ends of the surface are provided with the end plate made from non-magnet material, an end face wherein of end plate is provided with the flange identical with permanent magnet quantity, and two end plates is fixed on the yoke two ends and by the flange on it watt shape permanent magnet is pressed abd fixed on the yoke.
Here, in order securely a watt shape permanent magnet to be fixed on the yoke by flange, the both sides of watt shape permanent magnet are provided with chimb, and the both sides of end plate flange are provided with and watt recessed edge that shape permanent magnet both sides chimb matches.Like this, watt shape permanent magnet that will be positioned between two flanges by the recessed edge between adjacent two flanges of end plate is fixed.
Compared with the prior art the utility model has that manufacturing process is simple, manufacturing expense is low, the permanent magnetism physical efficiency is securely fixed in the advantage on the yoke cylindrical.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of end plate.
Embodiment:
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, comprise axle 1, be arranged on the column yoke 2 on the axle 1, be arranged on watt shape permanent magnet 3 on the column yoke 2, watt shape permanent magnet 3 peripheries are that the N utmost point and periphery are that the permanent magnet of the S utmost point is adjacent and be evenly distributed on yoke 2 external cylindrical surfaces, its special feature is that yoke 2 both ends of the surface are provided with the end plate made from non-magnet material 4, an end face wherein of end plate 4 is provided with the flange 5 identical with permanent magnet 3 quantity, two end plates 4 is fixed on yoke 2 two ends and by the flange on it 5 a watt shape permanent magnet 3 is pressed abd fixed on the yoke 2, the both sides of watt shape permanent magnet 3 are provided with chimb 6, and the both sides of the flange 5 on the end plate 4 are provided with the recessed edge 7 that matches with watt shape permanent magnet 3 both sides chimbs 6.
Here, flange 5 cross sections on the end plate 4 can be dovetail shaped, also can be stepped, and watt shape permanent magnet 3 cross sections of corresponding end plate 4 flanges 5 can be dovetail shaped, also can be stepped.
