Abstract
The invention relates to an insulating method for a motor stator. The method comprises the following steps of: preparation of an insulating varnish solution, preheating, temperature reduction, varnish impregnation, drying and the like. According to the method, the conventional twice varnish impregnation method for a motor stator component is changed, and the conventional twice varnish dripping treatment is changed into once varnish impregnation treatment by changing the viscosity of insulating varnish, so that a production cycle is shortened, and the consumption of the insulating varnish is reduced; and moreover, the preparation of two kinds of insulating varnish with different viscosities are not required, so that production management is simplified, the volume of a tunnel kiln is reduced, a space is saved, and energy sources are effectively saved.
Description
Technical field
The present invention relates to a kind of insulation processing technology, especially a kind of insulating treatment method of motor stator component.
Background technology
Motor is the electromagnetic and mechanical device of a kind of energy converting between mechanical or conversion of signals, in the production process of its stator module, need carry out insulation processing.At present, China's middle and small motor manufacturer generally adopts the dipping lacquer method 2 times.
Through after the preheating, when temperature drops to 60-80 ℃, carry out dipping lacquer one time at stator module, be filled into stator winding inside preferably in order to make insulating varnish; The viscosity of lacquer is lower, is typically chosen in when 20 ℃ BZ-4; About 18-22s, the time spent is long slightly, drips about 3min of lacquer time.And then carry out the secondary dipping lacquer, purpose is to form one deck paint film preferably on the primary insulation surface, and therefore the viscosity of lacquer should be big slightly, is typically chosen in 20 ℃; BZ-4, about 35-38s, the time spent is short slightly (if the time is oversize; Can paint film be damaged on the contrary, run counter to desire), about 1.5min.
Though the method for this 2 dipping lacquers can make motor stator component reach the effect that insulation is solidified, the insulating varnish consumption is bigger, and the dipping lacquer process time spent is longer, and power consumption is also just higher relatively.According to statistics, make in this way under normal circumstances, on average about each stator module dipping lacquer about 5-6min consuming time, power consumption is up to 0.15 degree, insulating varnish use amount 40g.
Summary of the invention
The insulating treatment method that the purpose of this invention is to provide a kind of motor stator reduces the insulating varnish use amount simultaneously, can save the energy and time again, with the needs of the large-scale production of satisfying motor.
Technology of the present invention carry into execution a plan into:
(1) configuration viscosity is 20 ℃, BZ-4, and the insulating varnish solution of 29-31s, and join in the dipping lacquer stove paintpot;
(2) motor stator is installed on the gripper of dipping lacquer stove rotates, carry out preheating then, temperature remains between 120～150 ℃, insulation 1min ± 10s;
(3) cooling, the time, temperature was reduced between 60～80 ℃ at 40～50s;
(4) the lacquer pipe that drips through the dipping lacquer stove partly drips insulating varnish solution to the stator coil of treating dipping lacquer of rotation, and the time is 1.2min ± 10s;
(5) heating in the dipping lacquer stove is ventilated, and the stator module of lacquer has been soaked in oven dry;
(6) take out check.
Wherein the temperature in the above-mentioned steps 2 is preferably 130 degree, and temperature retention time is preferably one minute.
In order to guarantee insulation solidification effect, must guarantee enough dripping the insulating varnish time with a dipping lacquer method; To guarantee that simultaneously preheating rear motor stator module temperature drops to 60-80 ℃.Temperature is too high, and a large amount of volatilizations fall in stator module and insulating varnish solvent contact, cause spillage of material; Moreover hot stator module surface, will form paint film rapidly, stop up the passage that the insulating varnish continuation is immersed, cause adverse consequences.Otherwise if the stator module temperature is low excessively, the temperature of the lacquer that then contacts with it will reduce, and the viscosity of lacquer increases, and flowability and permeability are relatively poor, also will cause the dipping lacquer weak effect.Draw through exploration practice constantly: the viscosity Control of selecting lacquer is at 20 ℃, BZ-4, and in the 29-31s scope, the dipping lacquer effect is best.
The present invention becomes 2 dipping lacquers and is 1 dipping lacquer through changing the viscosity of insulating varnish, and Min. ground changes each item performance, especially insulating properties, thermal conductivity, moisture resistance and the mechanical performance etc. of motor stator winding.Though the maximum difficulty of 1 dipping lacquer method is the choose reasonable of insulating varnish viscosity---low viscous lacquer can be penetrated into stator winding inside well, and it is few to coat with lacquer basic content, and after solvent evaporates, the space is more; Full-bodied lacquer is difficult to be penetrated into stator winding inside, stator winding promptly takes place ooze not phenomenon thoroughly.
The present invention adopts traditional 2 dipping lacquer methods of motor stator component that change, and through changing insulating varnish viscosity, changes 2 times original lacquer processing into 1 dipping lacquer and handles; Shortened the production cycle; Reduce the insulating varnish consumption, and need not prepare two kinds of different insulating varnish of viscosity and simplified production management, dwindled the continuous tunnel furnace volume; Save the space, practiced thrift the energy effectively.According to statistics, make in this way under normal circumstances, on average about each stator module dipping lacquer about 2min consuming time, power consumption is reduced to 0.07 degree, insulating varnish use amount 20.7g.
