Abstract
The invention relates to a motor stator punching plate. Winding slots are alternately formed in the stator punching plate through space teeth along the circumference, and the number of the winding slots is the odd times of four (starting from the five times of four), but does not include the common multiples of four and six. The motor stator punching plate can meet a variety of industry standards, the use ratio of silicon steel sheets is greatly increased, and the consumption of copper wires is significantly reduced. Therefore, the production cost is greatly reduced, and the requirements of material saving and consumption reducing are achieved.
Description
Technical field
The present invention relates to motor stator punching, be particularly suitable for but be not limited only to the stator punching of individual event asynchronous motor.
Background technology
Along with the fast development of China's economy, the non-renewable resources such as coal, oil, natural gas, and electric power and various raw-material consumption have increasingly sharpened, and the copper material of China comparatively lacks, iron ore resource needs a large amount of import.Under this situation, save material, reduce and consume, seem particularly important to improve economic and social benefit.For individual event asynchronous motor, the groove number of its traditional stator punching is mostly the multiple of 6, the benefit of such setting is that stator punching can be general in list, threephase motor, certain convenience is brought to production and administration, but this arrangement mode makes the utilance of silicon steel sheet lower, and winding copper cash consumption is comparatively large, and cost is higher, benefit is low, can not meet the requirement that new situations saving reduces.
Summary of the invention
The invention provides a kind of motor stator punching, to improve the utilance of silicon steel sheet, reduce copper cash consumption, production cost is reduced, reaches the requirement of materials saving.
Motor stator punching of the present invention, basic structure is circumferentially be provided with through spaced teeth slot for winding alternately on described stator punching equally, and the quantity of wherein said slot for winding is the odd-multiple at least from 5 times of 4, but does not comprise the common multiple of 4 and 6.Through a large amount of explorations and experiment, find the quantity of slot for winding on stator punching to be set to minimum be the odd-multiple of 20 4 and be not the common multiple of 4 and 6 time, compared with the stator punching of traditional same model, while its slot for winding number obtains effectively reducing, winding distribution ratio is larger than the winding distribution ratio under traditional slot for winding number layout, and the effective rate of utilization of winding is effectively improved.Be the ratio that the part model stator punching winding distribution ratio of the present invention of 5 multiples of 4 increases than traditional winding distribution ratio as table 1 indicates slot for winding.
Table 1:
Simultaneously, by table 2 be all slot for winding be 45 multiple stator punching experimental results it can also be seen that, in stator punching of the present invention, the angle of two adjacent winding slots increases, teeth portion width increases, simultaneously due to the change of slot for winding number layout, the calculation level of yoke minister degree is changed, therefore yoke portion have also been obtained growth, teeth portion density and yoke portion density (the magnetic field pressure drop that yoke portion is produced after powered up) also corresponding reduction, silicon steel sheet teeth portion magnetic conductive area is increased, the not only utilance that improve silicon steel sheet by a relatively large margin, also reduce motor winding copper cash consumption.
Table 2:
Although the present invention reduces on the distributed quantity of traditional stator punching slot for winding, if this and do not mean that reduce the quantity of slot for winding just can reach improve silicon steel sheet utilance, minimizing motor winding copper cash consumption object.Example is distributed as in the multiple mode that slot for winding is 3, although at this moment the layout quantity of slot for winding number is reduced, but the number of turn often organizing winding increases, the corresponding change because of groove area for each slot for winding makes the difficulty of winding inserting greatly increase, so also make the teeth portion width of stator punching and yoke portion height also corresponding subtract narrow and reduce, the availability of silicon steel sheet then can significantly reduce, permeability can reduce thereupon, therefore copper cash uses not only can not reduce can increase on the contrary, and motor property indices also can correspondingly decline.
On the other hand, when the groove number layout of stator punching is the even-multiple of 4, compared with the odd-multiple of employing 4, winding distribution ratio during odd-multiple is adopted also to be greater than the winding distribution ratio of even-multiple.For 5 multiples, φ 138mm stator punching that slot for winding is 4, when the slot for winding number of stator punching is the even-multiple of 4, compare odd-multiple and the distribution of traditional slot for winding number of 4, performance parameter declines all to some extent, comprise the effective rate of utilization of silicon steel plate is decreased, copper cash consumption is increased, motor breakdown torque is poor, and the various parameter such as motor winding temperature rise is higher, efficiency is poor.Result is as shown in table 3.
Table 3:
Preferably, the quantity of slot for winding is 20 or 28, and the raising of performance is particularly evident.
On this basis, the external diameter diameter of stator punching is preferably φ 105mm ~ φ 160mm.
Further, the axis of adjacent winding slots is 12.858 ° ~ 18 ° with the angle of stator punching central point.
Further, the yoke minister degree of stator punching is about 17 ~ 21mm mm.
Further, the teeth portion width of stator punching is about 3.7 ~ 7.3mm mm.
Test is learnt, motor stator punching of the present invention, not only can meet various industry standard, but also significantly improve the utilance of silicon steel sheet, the consumption decreasing copper cash of highly significant, makes production cost significantly reduce, and reaches the requirement of materials saving.
Below in conjunction with the embodiment of embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following embodiment.Without departing from the idea case in the present invention described above, the various replacement made according to ordinary skill knowledge and customary means or change, all should comprise within the scope of the invention.

Embodiment
The structure of motor stator punching of the present invention as shown in Figures 1 and 2 is circumferentially provided with through the alternate evenly distributed slot for winding 1 of spaced teeth 2 on stator punching, and the region between slot for winding 1 and edge, stator punching periphery is the yoke portion 3 of stator punching.The quantity of described slot for winding 1 is the odd-multiple at least from 5 times of 4, but does not comprise the common multiple of 4 and 6.For the quantity of slot for winding 1 be 45 multiples 20, stator punching external diameter diameter for φ 138mm, the axis of adjacent winding slots 1 is 18 ° with the angle α of stator punching central point, the length h1 in yoke portion 3 is about 17mm, and teeth portion width h2 is about 3.7mm, all larger than the parameter of traditional stator punching.For the YL series of secondary monopole asynchronous motor in monopole asynchronous motor, table 4, respectively with the power of identical motor and synchronous speed, indicates the motor and same model traditional single phase asynchronous motor comparing data in silicon steel sheet utilance and winding copper cash consumption that adopt the present embodiment stator punching.
Table 4:
As can be seen from the data of table 4, under equal conditions, adopt the motor of stator punching of the present invention to be significantly improved in silicon steel sheet utilance than same model traditional single phase asynchronous motor, and winding copper cash consumption also have and significantly reduce.
