Abstract
The utility model discloses a latent utmost point rotor magnet steel location structure, including rotor core, permanent magnet and end cover, the permanent magnet is hugged closely on rotor core's circumference surface, and the both ends of rotor core and permanent magnet are located respectively to the end cover, are in the same place rotor core with the permanent magnet is fixed. Because the utility model discloses location structure fixes the permanent magnet on the rotor core surface reliably, can avoid the relative motion between permanent magnet and rotor core when rotating at a high speed, therefore can show improvement motor reliability of operation.
Description
Technical field
This utility model relates to the magnet steel location structure of a kind of rotor, the magnet steel location structure of a kind of compressor permanent magnet machine rotor.
Background technology
At present, magneto use within the compressor is the most universal.Magnet steel for surface-mount type (SPM) permanent magnetism non salient pole machine positions mode, and the more commonly used is that magnet steel is directly bonded in iron core surface with glue, and this mode has the advantages such as simple in construction, low cost of manufacture, rotary inertia are little.But, owing to there is no mechanical position limitation, during rotor high-speed rotation, magnet steel may be made under the influence of centrifugal force to depart from rotor core.And for non salient pole machine, the general mechanical location mode using structure iron core protruding may cause saliency, motor performance is produced impact.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of at the rotor with non-salient poles magnet steel location structure ensureing significantly improve on the premise of motor has superior performance index rotor permanent magnet location and installation reliability.
For solving above-mentioned technical problem, this utility model one rotor with non-salient poles magnet steel location structure includes rotor core, permanent magnet and end cap, described permanent magnet is close in the circumferential exterior surface of described rotor core, described end cap is respectively arranged on the two ends of described rotor core and permanent magnet, described rotor core and permanent magnet is fixed together.
Above-mentioned a kind of rotor with non-salient poles magnet steel location structure, described end cap is fixed together with the riveting of described rotor core, and the two ends of described permanent magnet are respectively clamped in described end cap.
Above-mentioned a kind of rotor with non-salient poles magnet steel location structure, it is protruding that described rotor core surface is provided with V-type, and described permanent magnet is close in the circumferential exterior surface of the described rotor core between adjacent described V-type projection.
This utility model uses above-mentioned technical pattern, and magnet steel is securely fixed in iron core surface, can avoid the relative motion between magnet steel and iron core, improve motor reliability of operation during high-speed rotation by it.

Fig. 1 is the cross sectional representation of this utility model location structure；
Fig. 2 is the axial sectional diagrammatical view illustration of this utility model location structure；
Fig. 3 is the perspective view of this utility model location structure.
Detailed description of the invention
As it is shown in figure 1, this utility model rotor with non-salient poles magnet steel location structure includes rotor core 1 and permanent magnet 2, permanent magnet 2 is close in the circumferential exterior surface of rotor core 1.On the outer surface of rotor core 1, equalization is provided with V-type projection 11, and permanent magnet 2 is close to the circumference of the permanent magnet 2 between adjacent two V-type projections 11 in appearance respectively.Four permanent magnets 2, for the machinery location of permanent magnet 2, can be evenly distributed on rotor core 1 perimeter surface, can avoid the saliency that in existing design, iron core projection is brought simultaneously by V-type protruding 11.
As shown in Figures 2 and 3, this utility model rotor with non-salient poles magnet steel location structure also includes two end caps 3, being respectively arranged on rotor core 1 and the two ends of permanent magnet 2, end cap 3 is fixed together with rotor core 1 rivet 4 riveting, and the two ends of permanent magnet 2 are respectively clamped in end cap 3.
Permanent magnet 2 is securely fixed in rotor core 1 surface by this utility model location structure, can avoid the relative motion between permanent magnet 2 and rotor core 1, thus improve motor reliability of operation during high-speed rotation.Meanwhile, the end cap 3 at two ends can directly be got up by rivet 4 riveting, and assembly process process is good.
