Description
Technical field
This utility model relates to a kind of electromagnetism winding wire, particularly relate to a kind of stator coil gap lapping structure around
Group line.
Background technology
Linear asynchronous motor is mainly used in the straight-line motion mechanism of the bigger occasion of power, such as door operator, rises
The plant equipment hung, transmit and lift, drives vehicle, in particular for high speed and hypervelocity transport etc..The environment used is more severe
Carving, its related performance indicators requires height, and dominant electromechanical performance is Inverter fed motor, waterproof, and insulating barrier is thin and firm.
The insulation system that the winding wire of linear asynchronous motor is conventional is wrapped imines sintered membrane, mica tape, glass fiber leaching
The mode of stain paint mixing, or also imines film sintering, the mode of wrapped mica tape；The insulation system that both modes obtain,
All it is difficult to reach stator coil for Inverter fed motor, waterproof requirement, easily punctures.
Utility model content
In order to meet the performance specification needed for above-mentioned straight-line electric pusher, this utility model provides a kind of corona resistance
The winding wire of stator coil gap lapping structure that can be good with water resistance.
The technical solution adopted in the utility model is: the winding wire of a kind of stator coil gap lapping structure, including copper
Flat conductor, one layer of Inverter fed motor compound type insulating paint of copper flat conductor outer surface；The outside of Inverter fed motor compound type insulating paint is successively
It is surrounded with Kapton and mica tape.
In the winding wire of above-mentioned stator coil gap lapping structure, the outside of Kapton is surrounded with two stratus
Master tape.
In the winding wire of above-mentioned stator coil gap lapping structure, the cladding mode of Kapton is half lap
Bag, the cladding mode of mica tape is that gap is wrapped.
In the winding wire of above-mentioned stator coil gap lapping structure, mica tape around Inter-packet gap be 0.2～0.5mm,
The half that the adjacent spacing distance around Inter-packet gap is mica tape width of two-layer mica tape.
Compared with prior art, the beneficial effects of the utility model are: this utility model is at copper flat conductor outer surface
One layer of Inverter fed motor compound type insulating paint, has corona-resistance property good, the advantage that breakdown voltage is high；This utility model uses half-stack package
The wrapped mica tape of Kapton and gap as insulating barrier, preferable water resistance, it is possible to be guaranteed in the most severe ring
Longtime running under border.
Accompanying drawing explanation
Fig. 1 is this utility model sectional view radially.
Fig. 2 be this utility model vertically partly cut open topology view.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As shown in Figure 1, 2, this utility model includes copper flat conductor 1, and copper flat conductor outer surface one Inverter fed motor is combined
Type insullac 2, is coated with Kapton 3 and the two-layer Muscovitum of one layer of Inverter fed motor successively outside Inverter fed motor compound type insulating paint 2
Band 4；It is half-stack package that Kapton 3 is coated with mode, and the cladding mode of mica tape 4 is that gap is wrapped.
Described Inverter fed motor compound type insulating paint 2, its material uses the polyester-imide paint of 200 grades of Inverter fed motor and the poly-of Inverter fed motor
Amide imide paint, forms insulating barrier so that it is have corona resistance by the way of composite coated and a kind of technique completion of cure
Can be good, the feature that breakdown potential performance is high.
As in figure 2 it is shown, the Kapton 3 of described Inverter fed motor, use a lamellar spacing cladding, be half lap around packet mode
Bag (i.e. 48～the overlap of 50%)；2 layers of identical mica tape 4, its material can be chosen one side polyester film reinforcement low resin mica tape and implement
Cladding, or choose two-sided polyester film reinforcement low resin mica tape implement cladding form.Described mica tape 4 around packet mode be gap around
Bag；The wrapped gap F in gap in the range of: 0.2～0.5mm；The adjacent spacing distance D around Inter-packet gap of two-layer mica tape 4 is
The half (unit is mm) of mica tape width, its deviation should be less than 1.0mm.
Consisting of of mica tape: ground (30 μm mylar single-side reinforced)+70g mica paper.Wherein mylar should accord with
Close the requirement of GB/T 13542.4；Mica paper should meet the requirement of GB/T 5019.4.Mica tape contains accelerator, accelerator Zn2+
Content is (200～500) mgZn/m2；The glue content of mica tape is not more than 3～6%.Mica tape contains reversible self-adhesive, from
Viscose glue content is (1.7～1.9) %；The scope of whole insulation thickness H: 0.45～0.5mm.
