Abstract
The utility model discloses a stator punching sheet of a high voltage three-phase asynchronous machine. The stator punching sheet is characterized by comprising 48 stator punching sheet grooves, the external diameter of the stator punching sheet is 850mm, the internal diameter of the stator punching sheet is 460mm, the stator punching sheet is also provided with 48 through holes, the diameter of each through hole is 8mm, and center distance of the 48 through holes is 780mm. The stator punching sheet has ventilation and heat radiation functions, and size of the stator punching sheet can be adjusted according to magnetic density of a yoke portion of the punching sheet to realize the cooling purpose. The stator punching sheet can be used in a stator core of a high voltage highly efficient three-phase asynchronous machine Y2-HV500-2-1250KW10000VIP23, and is small in electromagnetic noise, low in temperature sound and high in efficiency.
Description
Technical field
The utility model relates to a kind of stator punching of high-voltage three-phase asynchronous motor, specifically is used for the stator core of high efficient, high pressure threephase asynchronous machine Y2-HV 500-2-1250KW 10000V IP23.
Background technology
In prior art, because that original traditional design is considered is not comprehensive, nonstandardization, the technology of auxiliary component does not catch up with, and often goes wrong, and is bad like radiating effect, temperature rise, efficient is low, and material does not make full use of; At present this a kind ofly improves design and can satisfy above deficiency.Be widely used in the motor in the fields such as industry, agricultural, commerce, building industry and traffic at present.
Stator punching is the key components and parts in the motor, and its material, interior round size, excircle dimension, aeration structure etc. have direct influence to the temperature rise of efficiency of motor, motor.And use maximum Y2 series high voltage motor in the market; Its stator punching can't reach the purpose that improves electric efficiency; Temperature rise is higher, and material does not make full use of, and realizes that in long-term use also there are defectives such as big, the warm sound pitch of electromagnetic noise, efficient be low in it.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point; Thereby a kind of stator punching of high-voltage three-phase asynchronous motor is provided; This stator punching ventilation and heat, the size in stator punching hole can reduce according to yoke portion close increase of magnetic of punching, reaches the purpose of cooling.
According to the technical scheme that the utility model provides, a kind of stator punching of high-voltage three-phase asynchronous motor comprises stator punching, and characteristic is: said stator punching is provided with 48 stator punching grooves; Said stator punching external diameter diameter is Φ 850mm; Said stator punching internal diameter diameter is Φ 460mm.
As further improvement of the present invention, be laid with 48 through holes on the said stator punching; The diameter of said through hole is Φ 8mm; The centre-to-centre spacing that said 48 through holes are distributed on the stator punching is Φ 780mm.
Compared with present technology the utility model has the following advantages:
The utility model stator punching ventilation and heat, the size in stator punching hole can reduce according to yoke portion close increase of magnetic of punching, reaches the purpose of cooling; The stator core that it is used for high efficient, high pressure threephase asynchronous machine Y2-HV 500-2-1250KW 10000V IP23 has characteristics such as electromagnetic noise is little, temperature sound is low, efficient height.
Description of drawings
Fig. 1 is the utility model 48 groove stator laminating structure sketch mapes.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, comprise stator punching 1.Said stator punching 1 is provided with 48 stator punching grooves; Said stator punching 1 external diameter diameter is Φ 850mm; Said stator punching 1 internal diameter diameter is Φ 460mm.Said stator punching 1 is provided with 48 through holes 3; The diameter in said hole is Φ 8mm; The centre-to-centre spacing that said 48 through holes 3 are distributed on the stator punching 1 is Φ 780mm.
The utility model only need change the diel of stator punching, on punch press, goes out stator punching with the 50WW470 cold-reduced silicon sheet, on the stator punching body, is provided with 48 Φ 8mm ventilating heat dissipating holes.The utility model scheme does not change original fit of motor.
The utility model is used for the stator core that height of center is a Y2-HV 500-2-1250KW 10000V IP23 motor, the stator punching ventilation and heat, and the size in hole can reduce according to yoke portion close increase of magnetic of punching, reaches optimal ventilation and heat.
