Shown in Fig. 1 to Fig. 7, according to an embodiment of the invention, a kind of motor is provided.Motor is especially in the present embodiment
Refer to the motor of compressor.
Motor in the present embodiment includes shell 40, motor stator and winding 60.Motor stator includes stator body 50
And insulation framework, when installation, insulation framework is mounted on stator body 50, and winding 60 is around being located at stator body 50 and insulation framework
In the structure of composition, then it is assembled in shell 40.
As described in background technology, the heat dissipation effect of existing motor is poor, in order to improve in the present embodiment
Motor heat dissipation effect, the insulation framework of motor is improved in the present embodiment.
Specifically, the insulation framework in the present embodiment includes ontology 10 and gap forming portion, the gap forming portion setting
The surface of ontology 10 and winding 60 around be located in insulation framework when form heat gap.
By being provided with gap forming portion on the ontology 10 of insulation framework in this present embodiment, when winding 60 is exhausted around being located at
When on edge skeleton, heat gap can be formed, by the effect of the heat gap, can be radiated to winding 60, electricity is reduced
The security risk of machine.
In a kind of preferred embodiment in the present embodiment, it sets gap forming portion to jog, when by winding 60
Around when being located in insulation framework, by the effect of jog, the enameled wire of winding 60 and connecing for insulation framework surface can be reduced
Contacting surface is accumulated, and heat gap is formed between enameled wire and jog, and then convenient for radiating to winding 60.
Preferably, the jog in the present embodiment is corrugated concaveconvex structure 20, the ripple of the corrugated concaveconvex structure 20
Trend is consistent with the direction of winding of winding 60, such as the arrow direction in Fig. 4, when by winding 60 around being located at corrugated concaveconvex structure 20
When upper, winding 60 and 20 contact surface of corrugated concaveconvex structure can be reduced to the maximum extent, and then can increase winding 60 and wave
Heat dissipation gap between line shape concaveconvex structure 20, convenient for radiating to winding 60.
Ontology 10 includes teeth portion 11, and when actual design, corrugated concaveconvex structure 20 is arranged in teeth portion 11.
Shown in Fig. 1 to Fig. 3, Fig. 5 to Fig. 7, in another preferred embodiment of the present invention, ontology 10 includes tooth
Portion 11, inner wall 12 and outer wall 13, teeth portion 11 is between inner wall 12 and outer wall 13
In the present embodiment, gap forming portion is set to connecting plate 30, which is connected to inner wall 12 and outer wall
Between 13, it is separate with side of the insulation framework far from corresponding stator body 50 that connecting plate 30 is located at teeth portion 11, and and teeth portion
11 formed heat gaps, when by winding 60 around be located in insulation framework after, pass through the heat dissipation between connecting plate 30 and teeth portion 11
The effect in gap, convenient for radiating to winding 60.
The both ends of connecting plate 30 in the present embodiment are both provided with reinforcing rib (not shown), pass through the work of the reinforcing rib
With, convenient for improve 30 connective stability of connecting plate, reinforce the stable structure of entire insulation framework, prevent insulation framework in coiling
It is excessive and produce fracture to occur stress concentration in journey.
The distance of connecting plate 30 to teeth portion 11 in the present embodiment is gradually reduced along the direction of outer wall 13 to inner wall 12, and interior
Wall 12, outer wall 13 and connecting plate 30 have predetermined deformation amount in winding winding 60.Connecting plate 30 is connected with outer wall 13
The distance of position to stator body 50 is not more than the top of inner wall 12 to the distance of stator body 50.That is, connecting plate 30
Thickness by coiling actual conditions depending on, can be carried out one by inner wall 12, outer wall 13 and connecting plate 30 when power in coiling
Quantitative deformation.The height of connecting plate 30 is gradually reduced from outer wall 13 to inner wall 12, i.e. β ≠ 0.
When motor works, rotor rotates the air-flow to form rotation, by the heat between copper wire winding 60 and stator body 50
Amount follows air-flow to distribute.
When carrying out coiling, winding 60 acts on power F1 at connecting plate 30, with increasing for coiling, gradually by connecting plate 30
It bends, as shown in Figure 7.Since connecting plate 30 is gradually recessed, so being also applied with power F2, F3 to outer wall 13 and inner wall 12, make it
To intermediate, inclined, the structure for wrapping coiling gradually is formed.
In existing insulation framework, distance of the winding 60 apart from shell 40 is a, has the exhausted of connecting plate 30 using the present invention
Edge skeleton so that distance increases b, it is clear that b > a, and then play and increase distance between winding 60 and shell 40
Effect, and outer wall 13 and inner wall 12 form the structure for encasing winding 60, enhance insulation performance, to increase climb electricity away from
From with reduce Leakage Current, reduce the security risk of motor.
As it can be seen that the teeth portion 11 of the insulation framework in the present embodiment is double-layer structure, one layer close to stator body 50 is just
Normal insulation framework, thickness is suitable with normal insulation skeleton, increases by one layer of more thin connecting plate 30 above it, passes through change
Material composition makes its material flexibility enhance, and a small amount of deformation can occur when encountering power, connects outer wall 13 and 12 part of inner wall.Two
It is hollow heat gap between layer, increases the area of 60 ingress of air of winding so that heat dissipation performance is just better than common insulation bone
The structure of frame, and when working, the heat of generation can together be scattered away with the air-flow that rotor rotation generates in hollow space.
The stress of coiling acts directly on connecting plate 30, makes connecting plate 30 to lower recess, connecting plate 30 and teeth portion 11 it
Between there are heat gap, at this moment top connecting plate 30 is to 12 applied force of outer wall 13 and inner wall, cause outer wall 13 and inner wall 12 to around
The side of group 60 tilts, and increasing with coiling, and outer wall 13 and 12 gradient of inner wall increase, and ultimately form the knot for encasing coiling
Structure, it is simple in structure, it is reliable and stable.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect:
(1) insulation framework of the invention can play the role of radiating and cooling, improve electric efficiency, extend motor and use the longevity
Life;
(2) insulation framework of the invention increases the distance between stator winding and shell, effectively prevents leakage current mistake
Greatly, and subsidiary creepage distance is increased;
(3) present invention is effectively increased the spacing between rotor inside insulation framework, reduces super hidden danger outside inboard wall of skeleton, carries
Lifting motor rotor concentricity.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
