Description
Technical field
The present invention relates to technical field of motors, particularly relate to a kind of magnetic slot-seal and winding manufacture method.
Background technology
Magnetic slot-seal is one of key fitment of large and middle size motor, and after its application, electric efficiency, power factor can improve, temperature rise, vibration, noise reduction.But at present at home the magnetic slot-seal that adopts of motor due to its structure and unreasonable with stator winding associated methods; after in embedding stator core slot; because of powered machine long-time running; produce the impact of heating and vibration; make magnetic slot-seal happen occasionally loosen even drop out outside stator slot; and then stator winding loosens or skids off outside groove, causes motor to be forced to stopping accident.
This situation more easily occurs in vertical machine.Magnetic slot-seal is by motor warming-up effect in addition, expands and protrude notch at the magnetic slot-seal of stator core notch, happens occasionally to rub mutually with the rotor surface rotated, and causes motor stopping accident.
Summary of the invention
The object of the invention is to, a kind of magnetic slot wedge structure is provided, to solve the problems of the technologies described above.
Another object of the present invention is to, provide a kind of magnetic slot wedge structure and winding all-in-one-piece method, to solve the problems of the technologies described above.
Technical problem solved by the invention realizes mainly through following technical measures:
A kind of magnetic slot wedge structure, comprise the magnetic slot-seal of a rectangular structure, it is characterized in that, the upper surface of described magnetic slot-seal is concave plane.
Though the upper surface of magnetic slot-seal runs fever expansion by motor, because magnetic slot-seal upper surface of the present invention is concave plane design, magnetic slot-seal is no more than stator core notch, so can not occur and rotor outer garden phase friction phenomenon.
The lower surface of described magnetic slot-seal is concave plane.The concave plane design of magnetic slot-seal lower surface of the present invention, can press tighter stator winding, arrange more solid and reliable.
The upper and lower surface of traditional magnetic slot-seal is set to concave plane by the present invention, and the planing of concave plane is convenient, simple.
The side, two ends of described magnetic slot-seal is respectively equipped with one for tying up the fixed groove without latitude strap.
Traditional magnetic slot-seal generally adopts the modes such as viscose paint to be fixed in stator core slot by the magnetic slot-seal of rectangular structure, the impact of heating and vibration is produced owing to being subject to motor long-time running, fixing of magnetic slot-seal is not firm, and the present invention is after the side, two ends of magnetic slot-seal arranges fixed groove, be placed into after in motor stator core groove at magnetic slot-seal, by without latitude strap by the fixed groove at magnetic slot-seal two ends and the colligation of stator winding both ends firm.Motor long-time running produces vibration, and magnetic slot-seal and stator winding become firm one and loosening dropping does not occur.The generation of peril has been stopped in design of the present invention, and motor property safe and reliable to operation improves.
The cross section of described magnetic slot-seal two sides is preferably triangle, and the both sides of described magnetic slot-seal are triangular prism structure, and described fixed groove is arranged on described triangular prism structure surface.Large and middle size motor stator winding because of power large, mostly be thicker hard wire coiling, so the groove of stator punching mostly is open slot, below groove, place stator winding, notch position places magnetic slot-seal, and below notch, cross section is opened on both sides is triangle mouth, like this in order to meet the above-mentioned specification of stator core slot, magnetic slot-seal side of the present invention also adopts cross section to be triangular structure, and such magnetic slot-seal injects after in groove, and upper-lower position is determined.
Different according to the specification of stator punching notch, the cross section of described magnetic slot-seal two sides can be isosceles triangular structure, also can adopt not isosceles triangular structure, to meet the shape need of stator punching groove.
Described concave plane, described fixed groove preferably adopt planer to plane and make.
A kind of magnetic slot wedge structure and winding all-in-one-piece method, adopt following steps by magnetic slot-seal and the integral setting of stator winding:
1) choose the magnetic slot-seal of rectangular structure, concave plane of the upper and lower surface of described magnetic slot-seal being planed out along its length, the left and right end of concave plane flushes with holding about magnetic slot-seal;
To be planed out in the both sides, front and back of described magnetic slot-seal the polygonized structure corresponding with stator core slot;
Side, two ends, the left and right through-thickness of described magnetic slot-seal to be planed out respectively fixed groove;
2) described magnetic slot-seal insertion be placed with in the stator core slot of stator winding, the fixed groove at two ends, described magnetic slot-seal left and right stretches out in described stator core;
3) by the fixed groove stretching out in stator core, colligation is carried out in the end, two ends of magnetic slot-seal and stator winding with without latitude strap;
4) stator core, stator winding, magnetic slot-seal are become to be integrated with without after latitude strap together vacuum paint dipping, oven dry.
Magnetic slot wedge structure of the present invention and stator winding without the colligation of latitude strap and together with dipping lacquer, be dried into integrated method, when motor long-time running, make planar expansion height of projection on magnetic slot-seal can not exceed the outer garden of notch, thus the phenomenon having stopped to wipe mutually in the outer garden of magnetic slot-seal and rotor occurs, magnetic slot-seal and stator winding integral after, magnetic slot-seal can not be there is because powered machine long-time running produces vibration to drop, and make the loose accident even skidded off outside stator core notch of stator winding.
Beneficial effect: adopt technique scheme, structure of the present invention is simple, manufacture craft is simple and convenient, and the integrative-structure made is solid and reliable, and motor is safe and reliable to operation.
