Abstract
A magnetic slot-wedge used on generator, with ferrous powder, adhesives and intensifying addictives mainly constituting a magnetic conductor and the surface of ferrous powder of the magnetic conductor wrapped by a phosphatising membrane. The utility model adopts the technical project of wrapping the surface of ferrous powder of the magnetic slot-wedge conductor with a phosphatising membrane to overcome the shortcoming that insulating ability and structural strength of the slot-wedge are affected by the raw common ferrous powder adopted by conventional magnetic slot-wedge used on generator and then further leading to the generator easy to be heated-up in operation. Compared with the prior art, the utility model has the characteristics that the high insulating ability and high magnetic conductibility of the conductor reduce eddy heating of the slot-wedge itself, improve operating efficiency of the generator and save energy. Meanwhile, materials are uneasy to degrade, thereby significantly extending the service life and suitable for a variety of magnetic slot-wedge used on generator.
Description
Technical field
The utility model relates to a kind of motor magnetic slot-seal, especially a kind of motor magnetic slot-seal that is made of magnetic conductor the phosphating coat iron powder.
Background technology
At present, mainly comprise iron powder in the magnetic slot-seal that generally uses in the motor.Undressed common iron powder is easily at motor generation eddy current in service, heating up, and the machine operation temperature rise improves, decrease in efficiency, and the easy accelerated material of heating that continues is aging, causes the loosening distortion of its slot wedge internal structure, influences the useful life and the motor reliability of operation of magnetic wedge groove.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of motor magnetic slot-seal, it had both had high magnetic conductivity and high structural strength, had the few heat of low eddy current again, and the motor operational efficiency improves and the operation of motor prolongation in useful life and high reliability but also have.
For achieving the above object, earlier iron powder being carried out phosphatization handles, make its surface be formed with the phosphating coat of resistance, select for use glass fibre to do to strengthen additive and be placed in the mould then, the iron powder that to handle is laid on the glass fibre again, it is evenly mixed with binding agent, topped again layer of glass on it, this is one deck, if any magnetic layer more than three layers, then repeat again more than twice, then three layers of magnetic layer are superimposed on together extrusion forming by above-mentioned steps, solidify the back and form the magnetic conductor magnetic slot-seal that contains magnetic layer more than three layers, magnetic conductor is mainly by iron powder, adhesive and enhancing additive constitute, and the surface of iron powder is surrounded by one deck phosphating coat, thereby realizes high magnetic conduction, low eddy-current heating and high-intensity effect.
The utility model adopts the technical scheme with the naked one deck phosphating coat of iron powder bag of magnetic layer in the magnetic slot-seal, overcome existing motor magnetic slot-seal, because of using undressed common iron powder to influence the insulation property of slot wedge magnetic layer, and then cause the be in operation defective of easy heating up of motor.
The utility model has compared to existing technology:
(1) because of being surrounded by phosphating coat, the iron powder surface of magnetic layer forms the phosphating coat that one deck has resistance, so improved insulation property;
(2) reduce the eddy-current heating of slot wedge own, the motor operational efficiency is improved, saved energy consumption;
(3) iron powder after handling wraps naked phosphating coat because of the surface and has effectively improved mutual adhesion strength between the iron powder, thereby has effectively improved the structural strength of magnetic layer interior tissue;
(4) raising of structural strength all is improved significantly stability, the reliability of motor operation;
(5) because of slot wedge itself has reduced eddy-current heating, so material is difficult for wearing out slot wedge significant prolongation in useful life.
Be suitable for various motor magnetic slot-seals.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model motor magnetic slot-seal schematic diagram.
Fig. 2 is the local enlarged diagram of motor shown in Figure 1 with magnetic slot-seal.
Fig. 3 is surrounded by the enlarged diagram of one deck phosphating coat for the surface of iron powder shown in Fig. 1.
Among the figure 1, iron powder, 2, adhesive, 3, strengthen additive, 4, phosphating coat.
Embodiment
Referring to accompanying drawing, a kind of motor magnetic slot-seal, it mainly comprises a magnetic conductor, this magnetic conductor is surrounded by iron powder 1, the adhesive 2 of one deck phosphating coat 4 and is strengthened additive 3 by the surface and constitutes.
Embodiment: earlier iron powder 1 is carried out alramenting and handle in phosphatization liquid, make iron powder 1 surface form the phosphating coat 4 that one deck has resistance, the iron powder of again phosphatization being handled 1 carries out dried, select for use glass fibre to make to strengthen additive 3 then, the glass fibre of choosing is placed in the mould, the iron powder 1 that to handle at last is laid on the glass fibre of mould, it is evenly mixed with binding agent 2, topped layer of glass on it, repeat above-mentioned steps again and continue on the glass fibre of mould, to add iron powder 1, binding agent 2, and with they even mixing, promptly carry out moulding after reaching more than three layers, pressurize and curing, obtain containing the motor magnetic slot-seal of multilayer magnetic layer at last.
Below only be an embodiment of the present utility model, according to above-mentioned design of the present utility model, those skilled in the art also can make various modifications and conversion to this.For example: the reconfiguration of magnetic layer, iron powder is carried out the variation and modification or the like that other modes are handled.Yet similar this conversion and modification all belong to essence of the present utility model.
Claims (3)
1, a kind of motor magnetic slot-seal, it mainly constitutes a magnetic conductor by iron powder (1), adhesive (2) and enhancing additive (3), it is characterized in that iron powder (1) surface of described magnetic conductor is surrounded by one deck phosphating coat (4).
2, a kind of motor magnetic slot-seal according to claim 1 is characterized in that described enhancing additive (3) is a glass fibre.
3, a kind of motor magnetic slot-seal according to claim 1 is characterized in that described magnetic conductor has three layers of magnetic layer at least.
