Abstract
The utility model provides a stator punching sheet for a two-pole single phase generator provided with ventilating slots, wherein an outer contour of a body of the punching sheet is formed by the connection of two straight line segments in parallel and a concentric circular arc segment which is adjacent and transitional to the straight line segments; an inner ring of the body of the punching sheet is evenly provided with wire embedded grooves in which machine windings are arranged, and all notches are arranged on the same circle; the utility model has the key points that wire embedded grooves right facing the two straight line segments are arched grooves, and notches of the arched grooves and notches of other wire embedded grooves are same in size, and areas of notches of the arched grooves are smaller than those of notches of the other wire embedded grooves. Under the condition of ensuring that the flux densities of yokes of the wire embedded grooves are almost the same, the stator punching sheet also has the advantages of material and cost saving, good heat dissipation effect and simple structure.
Description
Technical field
The utility model belongs to generator components, specifically, relates to a kind of bi-pole single-phase generator stator punching with ventilation slot.
Background technology
The line embedding groove that the stator punching of generator comprises yoke, is positioned at the endoporus of yoke central authorities and is evenly distributed on the endoporus periphery is respectively made by the silicon steel sheet punching press, the some overlapping formation stators that are fitted together of punching.
The shape and size of all line embedding grooves of traditional stator punching are identical.For the save silicon steel disc, outline is is normally connected and composed by two groups of (or one group) parallel segments and two sections (or multistage) concentric arc lines, but, because the line embedding groove size is identical, therefore, the yoke portion width of outline straight line portion is less than the width of outside circular arc portion, cause the former magnetic close, make the close difference of each magnetic of yoke to cause eddy current to be concentrated greater than the latter, finally cause the motor local pyrexia excessive, influence the overall performance of motor.
In order to address the above problem, Chinese patent ZL 200620110360.8 reduce parallel segment the area of right line embedding groove, as shown in Figure 1, over against straightway 6a, the line embedding groove of 6b is special- shaped groove 6c, 6d, this abnormity groove 6c, the part or all of bottom land of 6d is located along the same line, this straight line and corresponding straightway 6a, 6b is parallel to each other, and special-shaped groove 6c, and the area of 6d is less than the area of line embedding groove.This patent by reduce straightway to the area of line embedding groove, reached the purpose of the magnetic flux density basically identical that makes line embedding groove yoke portion, still, owing in the special-shaped groove coil will be installed, the area of line embedding groove can not be too little, and therefore, the effect of this patent economical with materials and cost is very limited; Because generator can produce a large amount of heats in running,, these heats can not influence the overall performance of generator again if in time leaving.
The utility model content
The utility model purpose is to provide a kind of bi-pole single-phase generator stator punching with ventilation slot, is guaranteeing further to reduce the material cost of generator under the prerequisite that each line embedding groove yoke portion magnetic flux density is consistent substantially, accelerates the heat radiation of generator.
The technical solution of the utility model is as follows: a kind of bi-pole single-phase generator stator punching with ventilation slot, and the outline of punching body is connected to form by the concentric circles segmental arc of two Line Segment and adjacent transition; Ring is evenly distributed with the line embedding groove that is used to settle motor windings in the punching body, and notch is positioned on the same circumference, its key is, described two straightways over against line embedding groove be deep-slotted chip breaker, this deep-slotted chip breaker notch size is identical with the notch size of line embedding groove, and the area of described deep-slotted chip breaker is less than the area of described line embedding groove.
The outline of above-mentioned punching body is evenly distributed with the welding breach along circumference, and the bottom of this breach is provided with the arc bonding pad.Can be by bonding pad so that iron core is formed in a plurality of stator punching stack welding.
Beneficial effect: the line embedding groove that the utility model will be relative with straightway should be ventilation slot, compare with prior art, the utility model also has economical with materials and cost when guaranteeing that line embedding groove yoke portion magnetic flux density is consistent substantially, good heat dissipation effect, advantage of simple structure.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 2, the outline of punching body 1 by two Line Segment 2 and adjacent transition with one heart
Arc section is connected to form; Ring is evenly distributed with the line embedding groove 4 that is used to settle motor windings in the punching body 1, and the notch of line embedding groove 4 is positioned on the same circumference, wherein, described two straightways 2 over against line embedding groove be deep-slotted chip breaker 3, this deep-slotted chip breaker 3 notches size is identical with the notch size of line embedding groove 4, and the area of described deep-slotted chip breaker (3) is less than the area of described line embedding groove (4).Certainly, except two straightways 2 described in the utility model over against line embedding groove be 3, two straightways 2 of deep-slotted chip breaker over against line embedding groove can be other special-shaped groove, just can in the high condition of the groove of line embedding groove as long as satisfy the groove higher primary school of special-shaped groove.
The outline of described punching body 1 is evenly distributed with the welding breach along circumference, and the bottom of this breach is provided with arc bonding pad 5, can be so that iron core is formed in a plurality of stator punching stack welding by bonding pad.
