Abstract
The invention provides a motor winding encapsulating process. The process comprises the flows of preparation, cleaning, pre-heating, proportioning of encapsulation raw materials, mold filling, vacuum-pumping, thermosetting and mold stripping. The invention has the advantages that a motor winding paint-immersion process is changed into the motor winding encapsulating process, and according to the encapsulation flows and under the accurate encapsulation control conditions, a stator and a rotor of a motor are integrated, so the insulation strength of the motor is improved, radiation is facilitated, and the motor winding encapsulating process can be safely used in severe environment such as high-temperature environment, low-temperature environment, vibration environment, vacuum environment and dust environment.
Description
Technical field
The invention belongs to the motor manufacture technology field, especially relate to a kind of motor windings dosing technology.
Background technology
In existing technology; Motor windings generally adopts the motor windings paint-dipping process; Such motor application can also satisfy the demands under general environment, still, and under adverse circumstances such as high temperature, low temperature, vibration, vacuum, dust; Safe handling requirement to motor is very high, and common motor process can not well satisfy the demands at present.
Also have the part motor windings to adopt dosing technology, but its flow process and condition control are not very accurate, the embedding poor effect.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned motor process, designed the motor windings dosing technology, motor is used safely under adverse circumstances such as high temperature, low temperature, vibration, vacuum, dust.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of motor windings dosing technology comprises the steps:
1) prepares: be ready to various tool, equipment, embedding grinding tool, treat the motor of embedding;
2) cleaning: clear up motor and the embedding grinding tool of treating embedding;
3) preheating: with the embedding grinding tool, treat that the motor of embedding is placed on preheating in the baking oven;
4) embedding proportioning raw materials: strictness is carried out proportioning with various raw materials in proportion;
5) dress mould: encapsulating die and location are installed to motor windings;
6) vacuumize: the embedding raw material is put into encapsulating die vacuumize, the emptying bubble;
7) thermosetting: strictness is carried out thermosetting by official hour, temperature;
8) depanning: with embedding good the motor depanning, and clean out.
Further, above-mentioned steps 2) when clearing up, the program of cleaning comprises that wind is washed and chemical cleaning, chemical cleaning adopts the insulation cleaning agent to clean the motor of treating embedding, adopts demoulding wax cleaning agent cleaning embedding grinding tool.
Further, above-mentioned steps 3) during preheating, embedding grinding tool, the motor of treating embedding put into 50 ℃～70 ℃ baking oven preheating 0.5～1 hour.
The percentage by weight of embedding proportioning raw materials further, above-mentioned steps 4) is following: bisphenol A epoxide resin 60%～70%, and curing agent 11%～15%, all the other are filler.
Further, above-mentioned steps 6) when vacuumizing, the embedding raw material is put into encapsulating die vacuumizes, vacuum degree between 40 Pascal to 100 Pascals, time remaining 5 minutes to 10 minutes.
Further, above-mentioned steps 7) temperature of thermosetting is between 60 ℃～70 ℃, and the time is 3 hours to 5 hours.
Further, the curing agent that uses as alicyclic polyamine, tertiary amine, narrow in azole and the boron trifluoride complex one or more.
Further, the filler of above-mentioned embedding proportioning raw materials is mainly formed by releasing agent, flexibilizer, silicon powder.
Advantage and good effect that the present invention has are: make the motor windings paint-dipping process into the motor windings dosing technology; The embedding flow process combines accurate embedding controlled condition; Motor stator, rotor are integral, increase electrical machine insulation intensity, be beneficial to heat radiation, can under adverse circumstances such as high temperature, low temperature, vibration, vacuum, dust, use safely.
