Abstract
Disclosed is a permanent magnet rotor. The permanent magnet rotor comprises a rotary shaft, a rotor iron core and permanent magnets uniformly arranged on the periphery of the rotor iron core, wherein the rotary shaft passes through a central hole of the rotor iron core to be matched with the rotor iron core; the permanent magnet rotor is characterized in that a stop plane is arranged on the rotary shaft at one end of the rotor iron core while a turning edge is arranged on the rotary shaft at the other end of the rotor iron core; the permanent magnets are inserted in penetration holes in the periphery of the rotor iron core; a first baffle for covering the permanent magnets in the penetration holes is arranged between one end of the rotor iron core and the stop plane arranged on the rotary shaft; and a second baffle for covering the permanent magnets in the penetration holes is arranged between the other end of the rotor iron core and the turning edge arranged on the rotary shaft. Compared with the prior art, the permanent magnet rotor has the advantages of simple manufacturing process, convenient and rapid assembling, and low cost.
Description
Technical field
The present invention relates to the technical field of motor..
Background technology
Existing permasyn morot p-m rotor, is by rotating shaft, rotor stop plate, rotor core, permanent magnet, circle spiral shell mostly
Mother matches somebody with somebody stop washer, and fixed structure of rotor is to coordinate stop washer locking by round nut；This structure existing problem is as follows：
1. assembly process is loaded down with trivial details, and operation inconvenience, efficiency of assembling is low；
2. there is certain thickness due to round nut in motor rotor construction, affect rotor axial size；
. it is threaded on motor shaft and stop washer screens groove, processing charges is high.
The content of the invention
The object of the invention is just to provide a kind of manufacturing process simply, easy to assembly quick, the p-m rotor of low cost.
What the object of the invention was realized in：Including rotating shaft, rotor core, it is uniformly arranged on the permanent magnetism of rotor core surrounding
Body, rotating shaft coordinates through rotor core centre bore with rotor core, and it is particular in that the rotating shaft of rotor core wherein one end
On be provided with only face, be provided with flange in the rotating shaft of the rotor core other end, permanent magnet insertion is arranged on rotor core periphery
In perforation, set stopping on rotor core wherein one end and rotating shaft be provided with first blocked permanent magnet in perforation between face
Baffle plate, to be provided between set flange on the rotor core other end and rotating shaft and block permanent magnet the second gear in perforation
Plate.
The present invention adopts turnup structure, therefore, with advantages below：
1st, it is easy to assembly, simple production process.
2nd, the processing charges of rotating shaft is reduced.
3rd, rotor axial compact dimensions；More spaces are brought to structure design.
Description of the drawings
Fig. 1 is the structural representation before flange of the present invention；
Fig. 2 is the structural representation after flange of the present invention.
Number explanation in figure：Rotating shaft 1, first baffle 2, rotor core 3, permanent magnet 4, second baffle 5, perforation 6, only face 7,
Flange 8, flange front rotary shaft thin-walled ring 8a.
Specific embodiment
With reference to the accompanying drawings and examples the invention will be further described
As shown in Fig. 2 what the object of the invention was realized in：Including rotating shaft 1, rotor core 3, it is uniformly arranged on rotor core four
The permanent magnet 4 in week, rotating shaft 1 coordinates through the centre bore of rotor core 3 and rotor core, its be particular in that rotor core 3 its
Only face 7 are provided with the rotating shaft of middle one end, flange 8 is provided with the rotating shaft 1 of the other end of rotor core 3, the insertion of permanent magnet 4 is arranged
It is set on the wherein one end of rotor core 3 and rotating shaft 1 to be only provided with forever between face 7 in the perforation 6 of the periphery of rotor core 3
Magnet 4 block perforation 6 in first baffle 2, be provided between set flange 8 on the other end of rotor core 3 and rotating shaft 1 by
Permanent magnet 4 blocks the second baffle 5 in perforation 6.
As shown in figure 1, during assembling, first first baffle 2 is pierced in rotating shaft 1 and abutted against on only face 7, rotor is then pierced into
Iron core 3, permanent magnet 4 is injected in the perforation 6 of the periphery of rotor core 3, then pierces into second baffle 5, finally will be turned with special equipment
Pre-processed flange front rotary shaft thin-walled ring 8a on axle 1 is turned over to turn 90 degrees and is become flange 8, by first baffle 2, rotor core 3,
Second baffle 5 is limited and is fixed on only face 7 and flange 8, so as to complete assembling structure as shown in Figure 1.
