Description
Technical field
The invention belongs to technical field of motors, particularly relate to a kind of silicon steel sheet slot wedge manufacture and installation method.
Background technology
As everyone knows, in the position that stator rabbet contacts with slot wedge, the skewness of air-gap field, causes the exciting curent of motor to increase, and the pulsating of rotor surface becomes large, and loss becomes large, and temperature rise increases, and efficiency reduces.Due to the motor operated under alternating current environment, slot wedge has the main flux of alternation pass through, must be subject to the electromagnet pull of a double power frequency, the size of this pulling force depends on the magnetic permeability of slot wedge material.Because cold rolling non-orientation silicon steel sheet has good magnetic permeability, the pulling force that slot wedge is subject to is larger.If slot wedge loosening, just double power frequency vibrations in groove.If at outer bread one deck insulating tape of silicon steel sheet, contribute to the contact surface abrasion reducing silicon steel sheet slot wedge and stator rabbet in vibrations process, prevent " mechanical erosion ".Therefore selected insulating tape also must have wear-resistant, the feature that surface roughness is large.Owing to silicon steel sheet slot wedge having main flux and slot wedge magnetic flux pass through, create magnetic hysteresis and eddy current loss, slot wedge temperature is raised, adds motor self-heating, resistant to elevated temperatures anaerobism glue must be used.
Because silicon steel is a kind of magnetically soft alloy, easy bending, and the outside of slot wedge is one deck insulating paper, to insert when slot wedge easily causes inserting the situations such as slot wedge bending, insulating paper displacement, insulating paper surface fracture by common method.In order to make the silicon steel sheet slot wedge being surrounded by insulating paper can be inserted into smoothly in stator core notch, the notch of stator core when inserting slot wedge, to be expanded as far as possible, therefore also need to design special frock to expand notch.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of silicon steel sheet slot wedge manufacture and installation method, the problem declined with the not high electric efficiency caused of the inductance solving existing motor stator.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of silicon steel sheet slot wedge manufacture and installation method, comprising:
1) some cold rolling non-orientation silicon steel sheets are gathered into folds formation lamellar body, fire resistant anaerobic adhesive water is coated in centre, is placed on below the smooth press in bottom surface, flattens;
2) the silicon steel sheet lamellar body flattened is put in baking oven, until dry;
3) after glue is dried completely, Linear cut silicon steel sheet lamellar body, cuts out the rectangular shape that size is suitable, cuts into round-corner transition at silicon steel sheet four angles;
4) three of the silicon steel sheet of rectangular shape face sticking insulating tapes of band are wrapped, and form slot wedge;
5) hand is put into slot wedge at the notch place of rule stator, and another hand uses wire pressing tool notch slowly to be strutted, until easily can insert slot wedge;
6) slot wedge is exposed to one of insulating tape facing to the enamelled wire in the notch of rule stator, and inserts along the notch strutted;
7) wire pressing tool continues to move toward notch depths, and constantly notch is strutted, another hand pushes away slot wedge lentamente to notch depths, until slot wedge is inserted in the notch of rule stator completely.
Beneficial effect
The present invention is applicable to high-end energy-conservation high efficiency motor, contributes to the inductance greatly improving rule stator.As everyone knows, in alternating current machine, the inductance of rule stator improves the operating efficiency contributing to improving motor, and the motor feels hot in minimizing, improves the rated power of motor, extends the useful life of motor.

Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Embodiment 1
As shown in Figure 1 to 4, a kind of silicon steel sheet slot wedge manufacture and installation method, slot wedge comprises silicon steel sheet 1, insulating tape 2, high temperature resistant function of glue coating 3, fillet 4, notch 5, stator iron core tooth 6, wire pressing tool 7, enamelled wire 8, rule stator 9;
1) some cold rolling non-orientation silicon steel sheets 1 are gathered into folds, fire resistant anaerobic adhesive water is coated in centre, is placed on below the smooth press in bottom surface, flattens.
2) silicon steel sheet 1 lamellar body flattened is put in baking oven, until dry.
3) after glue is dried completely, Linear cut silicon steel sheet lamellar body, cuts out the cuboid that size is suitable, has fillet at silicon steel sheet 1 two ends, to prevent the iron core slot of bump injury rule stator 9 in slot wedge insertion process.
4) three of silicon steel sheet 1 face sticking insulating tapes 2 of band are wrapped, make slot wedge.
As shown in Figure 3, the length of the stator core of this rule stator 1 is 137mm, stator punching internal diameter Φ 240mm, external diameter Φ 340mm, groove number 72 groove, use special wire pressing tool 7, and this wire pressing tool 7 can strut notch 5 width easily putting into silicon steel sheet slot wedge.
In order to make iron core inner circle air-gap permeance be evenly distributed, the insulating properties between each root slot wedge and iron core must be ensured, therefore universal instrument need be used to carry out insulating properties test between slot wedge and stator core, require that the contact position insulating properties of slot wedge and stator core is good.
