Abstract

The invention relates to an encapsulating process for a stator of a disk type motor. The encapsulating process comprises the following steps: step 1, workpiece preheating: the stator is preheated before encapsulating material is injected in; step 2, encapsulating material injection: the encapsulating material which is uniformly stirred is injected into the stator; step 3, vacuum defoamation: vacuum defoamation treatment is performed on the stator injected with the encapsulating material; step 4, heating and solidification: the stator is placed in a drying oven and heated so as to enable the encapsulating material to be completely solidified. Since the preheating step and the vacuum defoamation step are added, air inside the stator and contained in the encapsulating material is exhausted, so that cavities, gaps and other defects of the solidified colloid interior and surface of the motor stator after the treatment are not caused, and insulating performance and attractiveness in appearance of the stator are improved.

Description

A kind of dosing technology of disk type electric machine stator
Technical field
The present invention relates to field of motor manufacturing, relate in particular to a kind of dosing technology of disk type electric machine stator.
Background technology
Some motor stators, carry out insulation processing as the stator of disc type electric machine by embedding, and its dosing technology is generally: the injection of Embedding Material, be heating and curing or normal temperature cure.This dosing technology, have air because stator interior is residual, causes the rear inside of colloid curing and surface to there will be the defects such as cavity, air gap, affects the insulation property of stator.
Summary of the invention
The object of the invention is to overcome above defect, provide a kind of solidify rear without cavity, without the stator dosing technology of air gap.
For realizing purpose of the present invention, the present invention is achieved through the following technical solutions, a kind of dosing technology of disk type electric machine stator, and it comprises the following steps:
Step 1: the workpiece preheating, before injecting Embedding Material, stator is carried out preheating;
Step 2: Embedding Material injects, and the Embedding Material that stirs is injected stator;
Step 3: vacuum defoamation, the stator that has injected Embedding Material is carried out vacuum defoamation process;
Step 4: be heating and curing, stator put into baking oven heat and make Embedding Material solidify fully.
Preferably, described step 3 also comprises under normal temperature standing, and is namely standing at normal temperatures to the stator after vacuum defoamation;
Preferably, the preheat temperature of described step 1 is 80 ℃~120 ℃.
Preferably, be more than 15 minutes the warm-up time of described step 1.
Preferably, described standing be to carry out in lower than the environment of 80%RH standing at 25 ℃~30 ℃, relative humidity in temperature range.
Technique effect of the present invention is: by preheating step, vacuum defoamation step, the static step of normal temperature, make the air that stator interior air and Embedding Material contain be discharged completely, motor stator after such processing, colloid inside and surface after curing not there will be cavity, the defects such as gap, the aesthetics of raising stator insulation performance and outward appearance.
Embodiment
The invention will be further described below in conjunction with embodiment.
A kind of stator dosing technology, it comprises the following steps:
Step 1: workpiece preheating, before injecting Embedding Material, stator is carried out preheating, preheat temperature is controlled at 80 ℃~120 ℃, be not less than 15 minutes warm-up time, fully remove the moisture of stator, help the effusion of follow-up air and got rid of the part Embedding Material and may produce bad phenomenon with the steam reaction;
Step 2: Embedding Material injects, and the Embedding Material that stirs is injected stator;
Step 3: vacuum defoamation, the stator that has injected Embedding Material to be carried out vacuum defoamation process, vacuum degree is definite according to different Embedding Materials, and this step can effectively be removed air in stator; After vacuum defoamation, stator is placed in temperature range at 25 ℃~30 ℃, relative humidity is standing lower than carrying out in the environment of 80%RH, so that air has time enough to overflow;
Step 4: be heating and curing, the stator after standing put into baking oven heat and make Embedding Material solidify fully.
Owing to by increase preheating, vacuum defoamation, the static step of normal temperature, making the air that stator interior air and Embedding Material contain be discharged completely, make in the motor stator after above-mentioned processing colloid inside and surface after solidifying not there will be cavity, the defects such as gap, the aesthetics of raising stator insulation performance and outward appearance.
Be more than one embodiment of the present invention, a preferred demonstration example.The scope that the present patent application is asked for protection has more than and is limited to described execution mode.The technical scheme of all and the present embodiment equivalence, all belong to protection scope of the present invention.
