Abstract
The utility model relates to an exciter stator punching sheet, which comprises a stator punching sheet body. The body is a circular ring sheet, and 6 excitation winding portions distributed in circumferential mode are arranged in the inner circle of the circular sheet. The excitation winding portions are in a T shape, and a T-shaped winding groove is formed between two adjacent excitation winding portions. The exciter stator punching sheet is applied to an exciter. Users only need to change a punching mold of the stator punching sheet instead of changing an original assembling mode of the exciter. The stator punching sheet can improve the efficiency of the generator, and during a long-term use, electromagnetic noise is small, idle work energy consumption of the exciter can be reduced, and output efficiency of the exciter is improved.
Description
Technical field
The utility model relates to a kind of stator punching, is specifically related to a kind of exciter stator punching.
Background technology
The exciting power of pulling electric generator is bigger on the diesel-electric locomotive, and for providing exciting current the special field power supply that is provided with, promptly excitation generator is called for short exciter.Realize the desirable external characteristic of pulling electric generator through the control exciter.The general threephase alternator that adopts is directly driven through gearbox by diesel engine one pulling electric generator group, and the three-phase alternating current that sends is supplied power to the pulling electric generator excitation winding after the bridge rectifier rectification.Generally adopt inductor exciter on the locomotive; It is one three a different board-like alternating current generator; Its excitation winding and armature winding all are installed on the stator of motor; Do not have winding on the rotor, thus motor and external circuit get in touch sliding contact parts such as not needing brush and slip ring, thereby make that electric machine structure is simple, reliable operation, manufacturing cost are lower, be convenient to safeguard.
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 the exciter that uses in the market, oneself can't reach the purpose that improves generator efficiency its stator punching, and finds that in long-term use it exists also that electromagnetic noise is big, the low defective of efficient.
The utility model content
The purpose of the utility model is to provide a kind of exciter stator punching, and this stator punching is used for exciter, 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: the exciter stator punching; Comprise the stator punching body, said body is circular ring plate, and circle is provided with the excitation winding section of 6 circumferential arrangement in it; Said excitation winding section is " T " shape, forms the winding slot of " T " shape between two adjacent excitation winding sections.
Further, the length of the root that contacted with interior circle of said excitation winding section is 21.35mm.
Further, the opening length of said winding slot is 14.8mm.
When adopting technique scheme, the punching of the utility model exciter stator is used for exciter, only needs to change the diel of stator punching, does not change original fit of exciter.Circumferential arrangement winding slot on the interior profile has improved the utilance of material, has 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 exciter, improves the delivery efficiency of exciter.
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 exciter stator punching embodiment.
Embodiment
As shown in Figure 1, the punching of the utility model exciter stator mainly comprises stator punching body 1, and body 1 is circular silicon steel ring plate, and the excitation winding section 2 of the circumferential arrangement of 6 protrusions is arranged on the circle in it.Excitation winding section 2 is " T " shape, and the space between two adjacent excitation winding sections 2 forms the winding slot 3 of " T " shape.The root that is contacted with interior circle in excitation winding section 2, its length are d1=21.35mm.The length d 2=14.8mm of the peristome of winding slot 3.
This exciter stator is exclusively used in exciter, only need change the diel of stator punching during production, does not change original fit of exciter.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 exciter, improves the delivery efficiency of exciter.
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.
Claims (3)
1. exciter stator punching comprises the stator punching body, it is characterized in that; Said body is circular ring plate; Circle is provided with the excitation winding section of 6 circumferential arrangement in it, and said excitation winding section is " T " shape, forms the winding slot of " T " shape between two adjacent excitation winding sections.
2. exciter stator punching according to claim 1 is characterized in that, the length of the root that said excitation winding section is contacted with interior circle is 21.35mm.
