Description
Technical field
The present invention relates to field of motor manufacturing, more particularly to a kind of slot insulating paper and the motor with it.
Background technology
If Fig. 1-Fig. 4 is the slot insulating paper schematic diagram of the directly-wound concentration volume motor using resin matrix, usual motor
Stator slot can be inserted with slot insulating paper along cell wall, also, in order to prevent the winding close to stator tooth leading section and stator tooth front end
Occur pressure-resistant bad between portion, we would generally allow folding ear of the slot insulating paper along stator tooth leading section direction than stator tooth leading section
It is long.
Meanwhile, for convenience cast-over cabling we chamfered would generally be done to slot insulating paper, as shown in Figure 1.By this
The chamfered of sample, is the space that cast-over turnover stator slot opening portion leaves abundance, improves the transaction capabilities of coiling, favorably
In the raising of copper factor.
But, in practice, because slot insulating paper is typically by machinery operation consecutive production, if slot insulating paper
If imposing chamfered, then it is very easy to because machine is led at severing slot insulating paper junction because of the position deviation cut
Burr is caused to produce as shown in Figure 2.
Fig. 3 is that the preferable of slot insulating paper cuts process schematic, and Fig. 4 is that the actual process that cuts of slot insulating paper is illustrated
Figure, when actually cutting, because slot insulating paper can shift so that should be the structure of chamfering originally, easily produce burr.
As Figure 12, Figure 13 apply to the groove that plug-in type concentrates volume, volume motor is concentrated without using the directly-wound of resin matrix
Insulating paper in the schematic diagram of insulating paper, Figure 12, Figure 13 has a folding ear B turned up, during cutting, due to slot insulating paper
It can shift so that should be the structure of chamfering originally, easily produce burr.
And the burr produced can bring following shortcoming：
1st, slot insulating paper play is caused because encountering burr during cast-over turnover stator slot opening portion, position shifts.This
Sample can cause the defective insulation of iron core and winding or even occur burning damage accident.It is fatal for motor；
2nd, in compressor it is environment that a refrigerant and refrigerator oil mix, slot insulating paper can occur bad in such a case
Change, burr comes off as foreign matter after deterioration, it is possible to which the coolant path for blocking compressor causes compressor operating inefficiency, hair
Raw abnormal sound etc.；Being also possible to absorption causes compression mechanical part property abnormality in the compression mechanical part of compressor or even can not work.
The content of the invention
The present invention solves the technical problem of a kind of slot insulating paper and motor with it is provided, groove can solve the problem that

180°。
It is preferred that, when using secondary straight chamfering C, the distance between its adjacent secondary straight chamfering C bottom D2 scope
For 1mm~1.5mm.
It is preferred that, when the slot insulating paper A is in folded state, it includes：One bottom surface, symmetrical side, set
The folding ear A and the flanging of folding ear A outer ends being placed on the outside of side.
The invention also discloses a kind of motor with the slot insulating paper, described motor includes：Plug-in type collection
Middle volume motor, without using resin matrix directly-wound concentrate volume motor, using resin matrix directly-wound concentrate volume it is electronic
Machine.
It is preferred that, roll up motor or the directly-wound concentration volume motor without using resin matrix when being concentrated using plug-in type
When, the top edge of the slot insulating paper is additionally provided with folding ear B.
The beneficial effects of the invention are as follows：1st, slot insulating paper is avoided to produce burr in process of production, so as to avoid because of burr
Caused slot insulating paper position shifts the defective insulation problem brought, and reduces motor scaling loss risk；2nd, burr is avoided to take off
Fall to block coolant path or adsorb in compression mechanical part to cause compressor operating inefficiency, produce abnormal sound.
