Process method for overall vacuum encapsulation of permanent magnet motor stator

Abstract

The invention belongs to the field of permanent magnet motor stator processing, and particularly relates to a process method for overall vacuum encapsulation of a permanent magnet motor stator. The method comprises the steps that S1, a filling and sealing machine, organic silicon filling and sealing glue and a motor stator are prepared, a filling and sealing chamber is arranged in the filling and sealing machine, the filling and sealing chamber is in a sealed state, and the filling and sealing chamber can be opened through a sealing door; s2, putting the motor stator into a filling and sealing chamber, and starting a filling and sealing machine, so that the filling and sealing machine heats the motor stator in the filling and sealing chamber, and the temperature of the motor stator is kept at 120-140 DEG C; s3, evacuating the air in the potting chamber in the step S2, and then conveying the organic silicon potting adhesive into the potting chamber; the pouring sealant is vacuumized and compacted by using the pouring machine, so that the pouring sealant has a good pouring effect, and the pouring sealant is used for pouring the motor stator by using the organosilicon pouring sealant, so that the pouring effect of the motor stator can be greatly improved, and the service life of the motor stator is prolonged.

Description

technical field [0001] The invention relates to the field of permanent magnet motor stator processing, in particular to a process method for integral vacuum potting of a permanent magnet motor stator. Background technique [0002] The permanent magnet motor stator is assembled by the stator, the rotor and the end cover. The stator is an indispensable part of the permanent magnet motor motor. The stator is composed of magnets and casing bearings. [0003] At present, in the process of processing the stator, it is necessary to carry out an overall vacuum potting process for the stator. There are two kinds of potting methods: epoxy resin and silica gel. Silicone-based potting compounds have high thermal conductivity, but high viscosity and low strength after curing. Epoxy-based potting compounds are commonly used motor potting compounds. However, the traditional potting materials are not effective in vacuuming. Therefore, a process method for the overall vacuum potting of the ...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology and solve the problem that the traditional potting compound has a poor vacuuming effect, which in turn leads to the problem that the potting compound has a poor potting effect on the stator, the present invention proposes an integral vacuum potting of the stator of a permanent magnet motor process method
