Abstract
The invention relates to the field of the motor slot insulation technology, and in particular relates to a motor stator slot insulation sheet. The slot insulation sheet body is rectangular, and four top corners of the rectangle are respectively provided with a chamfer or a fillet transition. Since the four corners of the slot insulation sheet are provided with the chamfer or the fillet transition, the motor stator slot insulation sheet, in the automatic inserting winding process or the initial shaping process, does not generate the slot line or the line outside the slot which are caused by the sharp corner.
Description
Technical field
The present invention relates to the insulation technology field of motor slot, particularly a kind of motor stator notch insulating trip.
Background technology
Minimum range between the adjacent pole shoe of motor stator core is called stator rabbet, and the size of less stator rabbet can be improved the performance of motor greatly, experiment showed, that working as stator rabbet often reduces 1mm, and the efficiency of motor can improve 2%～3% left and right.When reality is used, stator rabbet can not be accomplished very little, generally can iron core is coated or insulating trip is set with insulating element coil is coated, thereby the enamelled wire being wound around to prevent directly contacts and damages enamelled wire with iron core.
Coil is coated and comprises bottom land insulation and notch insulation.Both at home and abroad in electromechanics trade, the stator rabbet insulation of the motor of most types is to adopt DND, DMD, phenolic aldehyde glass cloth sheet material to make, because these two kinds of materials of DND, DMD are convenient to equipment self-feeding, machine-shaping automatically, be convenient in the material storehouse of the equipment that is stored in, so these two kinds of materials are commonly used on semi-automatic and automation stator built-in line production equipment.
When existing domestic and international DND for equipment, DMD material processing notch insulating trip, adopt continuously, without waste material moulding gimmick.First, raw material is on discharge plate, and the width of raw material is the width of notch insulating trip; Secondly, feeding unit, cutter unit repeat the action of feeding-cutting-feeding-cutting, and the length of feeding can be regulated by machine intimate, and the length of each feeding is the length that cuts out notch insulating trip; In the time of notch insulating trip excision forming, be pressed in the material storehouse of equipment, in the process of enamelled wire winding inserting, the notch insulating trip leaving in material storehouse is pushed in stator slot, completes the automatic line inserting operation of stator.Due to adopt be continuously, without waste material moulding gimmick, as shown in Figure 1, a side of notch insulating trip has chamfering to the notch insulating trip that it processes, opposite side presents the tip-angled shape matching with described chamfering.When notch insulating trip is pressed in stator slot, its chamfering one side is introduced in stator slot, and this structure does not have problems in wire insertion technology.
But, because the stator coil of automatic line inserting is neat not, need to carry out just shaping, in the technique of just shaping, when the existence of this wedge angle very easily causes the copper factor of notch line or groove outside line, particularly stator core higher, the situation of notch line or groove outside line just more easily occurs.Notch line or groove outside line very easily cause electrical machine insulation performance bad, and severe patient causes motor to damage, and by the wedge angle of notch insulating trip, causes motor fraction defective to rise.
Summary of the invention
The object of the present invention is to provide a kind of motor stator notch insulating trip, effectively avoid the generation of notch line, groove outside line.
For realizing above object, the technical solution used in the present invention is: a kind of motor stator notch insulating trip, and notch insulating trip body is rectangle, and rectangular four drift angles are provided with chamfering or round-corner transition.
Compared with prior art; there is following technique effect in the present invention: due to chamfering or round-corner transition are all arranged to in four angles of notch insulating trip; remove the tip-angled shape that drift angle place overhangs out; no matter make it in automatic line inserting technique or first shaping process; can not produce because of the existence of wedge angle notch line, groove outside line, be conducive to the dielectric protection layer of assembling process to enamelled wire.

Embodiment
Below in conjunction with Fig. 2 to Fig. 5, the present invention is described in further detail.
Consult Fig. 2, a kind of motor stator notch insulating trip, notch insulating trip 10 bodies are rectangle, and rectangular four drift angles 13 are provided with chamfering or round-corner transition.Owing to having adopted chamfering or round-corner transition, no matter at automatic line inserting technique or first shaping process, can not produce because of the existence of wedge angle notch line, groove outside line, avoided because of the existence of wedge angle, causing in prior art the rising of motor fraction defective.In actual production, because the existence of notch line or groove outside line appears in motor stator, be the one of the main reasons that causes motor bad, be the appearance addressing this problem, technical staff did and repeatedly adjusts and improve each technique, but did not all deal with problems.Passed through afterwards technical staff's unremitting effort, just found that the main cause causing was because the wedge angle of notch insulating trip causes.In the stator manufacture craft of motor, automatic line inserting and just shaping belong to two different stations, notch insulating trip of the prior art meets the technique of automatic line inserting completely, and in first shaping process, just coil is arranged, being difficult for people is expected is because the notch insulating trip of placing in previous step causes.In actual production is manufactured, the notch insulating trip after change has obviously changed the appearance of notch line, groove outside line, and the yields of motor gets a promotion.
Two drift angles 13 that it is pointed out that the left side in Fig. 2 are round-corner transition, and two drift angles 13 on right side are chamfering.Four drift angles 13 of notch insulating trip 10 also can be chamfering, or are all round-corner transitions.Only otherwise occurring tip-angled shape of the prior art.
As preferred version of the present invention, the present invention here is preferably round-corner transition by four drift angles 13 of described rectangle.The size of described rectangular length and width and motor stator matches, consistent with length and width of the prior art.
More preferably, described notch insulating trip 10 is formed by automatic cutoff equipment surface trimming, change due to notch insulating trip 10 shapes, after being cut the raw material of strip, automatic cutoff equipment can produce clout, therefore, need to transform automatic cutoff equipment, described automatic cutoff equipment is provided with blanking unit.In addition, it should be noted that, because the notch insulating trip 10 being pressed in material storehouse is bending, as shown in Figure 3, notch insulating trip 10 after bending comprises interlude 11, side segment 12, when if the distance of chamfering equals the width of side segment 12, the notch insulating trip 10 after bending is also angular existence in bending place; If the radius of the distance of chamfering or fillet is greater than the width of side segment 12, its insulation effect is poor, therefore, in the present embodiment, preferably, the chamfering at drift angle 13 places or fillet is arranged in side segment 12.Fig. 4, Fig. 5 are the position of notch insulating trip 10 in stator, and wherein A represents coil.
