Description
Technical field
The present invention relates to pump motor technical field.
Background technology
It is as shown in Figure 1 a kind of alternating current permanent magnet synchronous water discharge pump, available for washing machine, dish-washing machine, foot basin, jacuzzi
Deng on electrical equipment.The basic structure of the alternating current permanent magnet synchronous water discharge pump includes rotor assembly 3, stator core 4, coil 5, the pump housing 7, wind
Leaf 2 etc..P-m rotor, armature spindle and axle sleeve, which tighten together, constitutes rotor assembly 3.Coil 5 is assemblied on skeleton, coil 5
The alternating magnetic field produced after energization drives rotor assembly rotation by stator core 4, and rotor assembly coupling fan blade is rotated.Coil by
Into stator coil after enamel-cover round wires (see standard GB/T 1193-74) coiling.Because enamel-covered wire is generally very thin, coil is difficult into
The processing of row varnished insulation, the need for being environmental protection, prior art mainly carries out plastic packaging formation coil overmold to coil, in detail
It can be seen that draining pump configuration disclosed in Publication No. CN101102068 Chinese invention patent application.
But, during superposition is wound on coil rack 9 using circular enamel-covered wire on draining pump motor, up and down
Mutually be close to three circular enamel-covered wires 10 on section into triangle disposition structure, as shown in figure 3, per two adjacent round wires paints
The gap 11 for being similar to triangle can be formed between envelope curve.Particularly in the draining pump motor of high-power big line footpath, around
After number of wire turns increase, these idle gap accumulations will be produced than larger idle space together.For the water of coil plastic packaging
Pump, in motor operation, coil temperature rise, these air meeting expanded by heating, but be difficult to pass through the plastic packaging with sealing function
Layer release, causes the plastic packaging layer of coil to produce the undesirable conditions such as bulge, deformation.For the problem, plastic packaging layer is taken perforate,
Crack design, but these ways weaken the environmental protection effect for even destroying plastic packaging layer unavoidably.
The content of the invention
Coil overmold, which can be solved, there is provided one kind it is an object of the invention to solving background technology described problem bulge occurs
The pump motor of problem.
To achieve these goals, present invention employs following technical scheme：A kind of pump motor of use coil overmold,
Including rotor assembly, the pump housing, stator core and the stator coil to rotor assembly offer support, institute for driving fan blade to rotate
The coil windings for stating stator coil are wrapped in after coil rack by metal enamel conductor and constituted, and coil windings are wrapped in plastic packaging housing
Within, the metal enamel conductor is made up of insulation crust and the plain conductor being wrapped within insulation crust, the insulation crust
Cross section outline be rectangle.
Preferably, the cross section outline of the insulation crust is square.
The plain conductor is aluminum steel.
The coil windings of the present invention use the enamel-covered wire coiling with rectangle foreign steamer Guo to form, and such a construction reduces phase
Gap between adjacent circle, greatly reduces open ended air in coil plastic packaging layer, when motor operation coil temperature is raised, gas
Body expanded by heating amount is reduced therewith, though plastic packaging layer not perforate, crack to discharge air, coil is not allowed to be also easy to produce bulge yet.

Embodiment
It should be understood that upper and lower, left and right in this specification, directional terms are to be directed to upwards, downwards, to the left, to the right
The description in the orientation shown in accompanying drawing, these orientation are not restricted.If without certain illustrated, term herein to
Interior, outside, inside and outside, inner side, outside refer to the scope relative to part centre, such as using electrical axis as reference, interior and interior
Side refers to closer to or pointed to position or the orientation of electrical axis, and outer and outside refers to further from motor center position.In addition, term
Level, the term such as hold up, dangle and be not offered as requiring part abswolute level or pendency, and allowing to be slightly tilted.Such as level
More level is simply meant to for its direction opposed vertical, is not to represent that the structure is fully horizontal, but can be slightly tilted.
It is as shown in Figure 1 a kind of alternating current permanent magnet synchronous water discharge pump, available for washing machine, dish-washing machine, foot basin, jacuzzi
Deng on electrical equipment.The alternating current permanent magnet synchronous water discharge pump includes pump cover 1, fan blade 2, the rotor assembly 3 for driving the rotation of fan blade 2, determined
Sub- iron core 4, coil overmold 5 and pump housing 7 for supporting rotor assembly etc. are constituted.Rotor assembly 3 by p-m rotor, armature spindle and
Axle sleeve is constituted.Aluminium enamel-covered wire, which is wound in after coil rack 9, turns to coil windings, and coil windings are wrapped in coil plastic packaging layer 8
Within, constitute coil overmold 5.The alternating magnetic field that coil overmold 5 is produced after being powered drives rotor assembly certainly by stator core 4
Turn, so as to further promote fan blade 2 to rotate.
As shown in figure 5, enamel-covered wire is made up of insulation crust and the plain conductor being wrapped within insulation crust, insulation crust
Outline be rectangle, i.e. rectangle enamel-covered wire 12.As can be seen from FIG., two of same layer adjacent enamel-covered wires and adjacent layer
Equal good fit between enamel-covered wire, forms straight laminating side 13, substantially without space.
It is compared below with data citing.Φ 0.45mm circular enamel-covered wire is used on L1 × L2 region in Fig. 4
Coiling, wherein L1=30.5mm, L2=3.2mm, the coiling number of turn is 532 circles, then the effective area of circular enamel-covered wire is taken than being π
×(0.45÷2)2× 532 ÷ (30.5 × 3.2)=86.7%.In Figure 5, use instead and justify enamel-cover line footpath sectional area with Φ 0.45mm
Equal square enamel-covered wire carries out coiling, and the length of side is sqrt (π × (0.45 ÷ 2)2)=0.4mm.If we do not change motor
Number of turns, the same circle of coiling 532, L1 × L2=30.5 × 2.8 can then be narrowed down to by this moment accommodating the region of square enamel-covered wire
Requirement can be just reached, i.e., we can reduce skeleton size, and it is 0.4 that the effective area of square enamel-covered wire, which takes ratio,2×532
÷ (30.5 × 2.8)=99.7%.If region L1 × L2 is constant, the number of turn is that can increase to 608 circles, and rectangle enamel-covered wire
Effective area is taken than being 0.42× 608 ÷ (30.5 × 3.2)=99.7%.From data comparison, relative to circular enamel-cover
Line, an equal amount of conductor cross sectional area of coiling, and in the case where winding area size is constant, reduce by 13% clearance air,
Coil plastic packaging layer 8 is accordingly reduced by gas tension, significantly reduces its bulge, the degree of deformation.
The insulation crust of enamel-covered wire can use existing high-strength polyester material.
Limitation is not applied to exchange synchronous draining pump forever, other pump motors to the present invention, as long as its coil uses paint
The coiling of envelope curve institute, can apply this structure.
The present invention include but is not limited to above-described embodiment and content shown in the drawings, it is other all with the present invention technology
The product structure that scheme has identical essentiality content is each fallen within protection scope of the present invention.
