Abstract
The utility model relates to a stator punching sheet. The outer outline of the stator punching sheet is provided with four line segments which are symmetric and two circular arc segments which are protruded, the distance between the opposite line segments is 257mm, the inner outline of the stator punching sheet is provided with thirty-six coiling slots, four circular holes are arranged at the periphery between the outer outline and the coiling slots, a T-shaped coiling part is arranged between the two adjacent coiling slots, the dimension of each coiling slot and the dimension of the opening of the inner outline are 3.8mm respectively, the width of each coiling part is 5.8mm, and the diameter of the circular inner outline is 158mm. In the utility model, only a punching mould of the stator punching sheet is changed, and the original assembly mode of a generator does not need to be changed; and as the coiling slots are arranged on the inner outline, the utilization rate of a material is improved, and more coiling slots are provided. The stator punching sheet disclosed by the utility model has the advantages that the efficiency of the generator is improved, the electromagnetic noise is small during the long-term use process, the reactive energy consumption of the generator can be reduced, and the output efficiency of the generator can be improved.
Description
Technical field
The utility model relates to a kind of generator stator punching sheet.
Background technology
At present, generator is widely used in the fields such as industry, agricultural, commerce, building industry and traffic, and ubiquity defectives such as efficient is low, energy consumption is big, can not satisfy the requirement of efficient and energy-saving and emission-reduction.
Generator unit stator is that the stator punching monolithic is formed by stacking, and coil winding is on generator unit stator.The generator of different model has the stator punching of the unified size of different model, and stator punching is the key components and parts in the generator, its material, interior round size, outside dimension, flute profile size, what etc. the efficient of generator is had direct influence.And using generator in the market, oneself can't reach the purpose that improves generator efficiency its stator punching, and finds that in long-term use also there is big, the inefficient defective of electromagnetic noise in it.
The utility model content
The purpose of the utility model is to provide a kind of stator punching, and this stator punching is used for generator, and in long-term use, electromagnetic noise is little, efficient is high.
For achieving the above object; The technical scheme of the utility model is: stator punching; Comprise the stator punching body, said body outline has straightway and two outstanding arc sections of four symmetries, and the distance of two relative straightways is 257mm; Profile is provided with 36 winding slots in it, and circumferential row is shown 4 circular holes between outline and winding slot; " T " shape winding section is arranged between said two adjacent winding slots, and said winding slot and interior profile opening are of a size of 3.8mm; The width of winding section is 5.8mm, and the diameter of the interior profile of said circle is 158mm.
Further, the chord length of said outstanding arc section is 53mm.
Further, the diameter of said circular hole is 4mm.
When adopting technique scheme; The utility model stator punching, its outline have straightway and two outstanding arc sections of four symmetries, and the distance of two relative straightways is 257mm; Profile is provided with 36 winding slots in it, and circumferential row is shown 4 circular holes between outline and winding slot; " T " shape winding section is arranged between said two adjacent winding slots, and said winding slot and interior profile opening are of a size of 3.8mm; The width of winding section is 5.8mm, and the diameter of the interior profile of said circle is 158mm.Only need to change the diel of stator punching, do not change original fit of generator, arrange winding slot on the interior profile, improved the utilance of material, have more winding slot.This stator punching can improve the efficient of generator, and in long-term use, electromagnetic noise is little, can reduce the idle energy consumption of generator machine, improves the delivery efficiency of generator.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model stator punching embodiment.
Embodiment
As shown in Figure 1; The utility model stator punching; The outline of body 1 has straightway and two outstanding arc sections of four symmetries, the chord length d6=53mm of arc section, and the distance of two relative straightways is d1=257mm; Profile is provided with 36 winding slots 2 in it, and circumferential row is shown the circular hole 3 of 4 diameter d 5=4mm between outline and winding slot 2; " T " shape winding section 4 is arranged, the size d2=3.8mm of said winding slot 2 and interior profile opening between said two adjacent winding slots 2; The width d3=5.8mm of winding section 4, the diameter d 4=158mm of the interior profile of said circle.
This stator punching only needs to change the diel of stator punching, does not change original fit of generator; This stator punching can improve the efficient of generator, and in long-term use, electromagnetic noise is little; Can reduce the idle energy consumption of generator machine, improve the delivery efficiency of generator.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection range of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
