Abstract
The invention discloses a stator punching sheet of a high-pressure three-phase asynchronous motor, which comprises a stator punching sheet. The invention is characterized in that 48 stator punching sheet grooves are arranged on the stator punching sheet; the outer diameter of the stator punching sheet is [phi]850mm; and the inner diameter of the stator punching sheet is [phi]460mm. 48 through holes are uniformly distributed on the stator punching sheet; the diameter of the through holes is [phi]8mm; and the center distance of the 48 through holes distributed on the stator punching sheet is [phi]780mm. In the invention, the stator punching sheet has good ventilation and heat dissipation effects; the size of the stator punching sheet can be increased or reduced according to the magnetic density of the yoke part of the punching sheet so as to reduce temperature; and moreover, the stator punching sheet is applied to the stator core of a high-pressure efficient three-phase asynchronous motor Y2-HV500-2-1250KW10000VIP23, and has the characteristics of low electromagnetic noise, low temperature rise, high efficiency and the like.
Description
Technical field
The present invention relates to a kind of stator punching of high-voltage three-phase asynchronous motor, specifically be 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 objective of the invention 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 technical scheme provided by the invention, 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 present invention has the following advantages:
Stator punching ventilation and heat of the present invention, 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 present invention's 48 groove stator laminating structure sketch mapes.
Embodiment
Following the present invention 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 present invention 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 present invention program does not change original fit of motor.
The present invention 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.
