Description
Technical field
The present invention relates to and a kind ofly mix laminating stator iron core and manufacturing the application in power motor again, belong to motor and manufacture field again.
Background technology
Along with energy crisis and environmental pollution are day by day serious, Development of Electric Vehicles is swift and violent.In China, expect the year two thousand twenty, the learies of permagnetic synchronous motor will reach 200,000, and in power motor, the material weight of iron core accounts for 50% of motor weight, and its cost accounts for about 20% of motor body.Therefore scrap dynamo sheet enormous amount, if can not rationally process, not only will bring problem of environmental pollution, and also can cause the huge wasting of resources.Therefore, the again manufacture of scrapping the old permagnetic synchronous motor of motor of service life more than 5 years how is utilized will to be problem demanding prompt solution for electric automobile.

Fig. 1 is that the present invention's mixing stator core specifically implements stereoscopic schematic diagram;
Fig. 2 is that iron-based amorphous alloy ribbon material strip folds block;
Fig. 3 is that empty load of motor loss is with rotation speed change trend;
Number in the figure: 1 mixing laminating stator iron core, 11 silicon steel laminations core packets, 12 Fe-based amorphous alloy core packets, 121 Fe-based amorphous alloy blocks.
Embodiment
See Fig. 1, mixing laminating stator iron core 1 in the present embodiment is be overrided to form axially spaced by the silicon steel laminations iron core of the waste and old motor through dismounting and Fe-based amorphous alloy iron core.
As depicted in figs. 1 and 2, mutually laminated form silicon steel laminations core packet 11 by multi-disc silicon steel sheet, mutually laminated by multi-disc Fe-based amorphous alloy sheet and form Fe-based amorphous alloy block 121, Fe-based amorphous alloy block 121 linear cutter becomes Fe-based amorphous alloy core packet 12; Formation mixing laminating stator iron core 1 is jointly laminated in interval one by one with silicon steel laminations core packet 11 and Fe-based amorphous alloy core packet 12; Namely silicon steel sheet refers to the silicon steel sheet in the silicon steel laminations iron core of the waste and old motor of dismounting.
In concrete enforcement, corresponding vibrational power flow also comprises:
Mixing laminating stator iron core 1 is set to silicon steel laminations core packet 11 respectively at two ends; cause lower, the easy fracture of Fe-based amorphous iron core laminated coefficient to be peeled off because Fe-based amorphous alloy laminate is thin, hard, crisp; mixing laminating stator iron core two ends are set to silicon steel laminations core packet, can play and protect amorphous alloy material and the effect improving the stacking factor of non-crystaline amorphous metal laminated core.
In mixing laminating stator iron core 1, the volume fraction that Fe-based amorphous alloy iron core accounts for mixing laminating stator iron core 1 is 30% ~ 50%, manufacturing one of main purpose is again be to save material, in order to make a large amount of cycling and reutilization of old silicon steel sheet, the volume fraction upper limit of Fe-based amorphous alloy core packet is 50%; Although iron-base amorphous alloy material loss is only 1/6th of silicon steel material loss, but its saturation magnetic induction is on the low side causes motor torque to shrink, again motor is manufactured higher than Fe-based amorphous alloy saturation magnetic induction for the magnetic flux density design load of stator core, manufacture motor torque again and shrink to reduce and improve electric efficiency, the volume fraction lower limit of Fe-based amorphous alloy core packet is 30%.
Silicon steel laminations core packet 11 and Fe-based amorphous alloy core packet 12 are annular section, and the axial length of each annular section is equal.Because the characteristic of magnetization of two kinds of soft magnetic materials is different, cause different materials core packet and air-gap field distribution difference, in order to ensure the symmetry mixing iron core motor axial magnetic field, the inner shaft of motor that elimination different materials causes is to the asymmetry in magnetic field, and the axial length arranging every section of stator core is equal.
The thickness arranging every sheet silicon steel sheet in silicon steel laminations core packet 11 is 0.2mm, 0.35mm or is 0.5mm, and in Fe-based amorphous alloy core packet 12, the thickness of every sheet Fe-based amorphous alloy sheet is 0.027 ~ 0.03mm.
In power motor, adopt mixing laminating stator iron core 1, electric motor end cap and rotor portion remain electric motor end cap and the rotor portion of the waste and old motor through dismantling.
One aspect of the present invention takes full advantage of old motor-stator silicon-steel sheet; On the other hand, due to the low loss characteristic of Fe-based amorphous alloy excellence, make to mix the 40%-60% that laminating stator core loss is former stator core loss, make to manufacture rear motor efficiency again and improve 1-2%, with rotation speed change as shown in Figure 3, curve A is that old empty load of motor loss is with rotation speed change trend to mixing iron core motor no-load loss; Curve B is that the present invention's mixing iron core manufactures empty load of motor loss again with rotation speed change trend.
The hop count of mixing laminating stator iron core depends on the magnetic flux density design load manufacturing motor stator core again, with manufacture again electric efficiency promote and torque meets the demands as target obtains optimum hop count, in addition, the Fe-based amorphous alloy iron core of mixing also can change the soft magnetic material of other superior performances into.
