Problems solved by technology
[0003] 1. The two-component structure is mostly used. When using it, the two components must be mixed and blended evenly. During the blending process, a large amount of air will be mixed due to stirring.
[0004] 2. After the two-component potting glue is evenly mixed and prepared, as the temperature rises, the viscosity will decrease and the fluidity will increase, but at the same time the curing time will also be shortened
[0005] The invention patent with the authorized notification number of CN 102005874 B discloses a vacuum potting process for motor stator slots. The potting glue of the composite component is used. Before mixing and stirring the various components of the potting glue of the composite component, first Pour the component glues that make up the composite glue into the mixing container, and then seal the container for vacuum treatment, so that the various component glues in the container are stirred in a vacuum state, so as to prevent the air from being dissolved into the composite components during stirring. In the potting glue; the potting glue of the mixed composite component is vacuum potted to the slot area of the stator through the pipeline for vacuum potting; this patent can reduce the cost of the potting glue of the composite component It is possible for each component to generate air bubbles during stirring, and there will be no phenomenon that the air bubbles will dissolve into the potting compound of the composite component; however, it does not mention how to improve the fluidity of the potting compound and how to accelerate the curing of the potting compound

The invention also discloses a motor stator vacuum constant temperature epoxy potting process. The invention solves the problem of foam holes generated when the conventional motor stator is potted, improves the sealing performance and thermal conductivity of the motor stator, thereby improving the heat dissipation, dustproof and anti-corrosion capabilities of the motor.
Description
technical field [0001] The invention relates to the field of motor stator potting, in particular to a motor stator vacuum constant temperature epoxy potting device and potting process. Background technique [0002] Motor stator potting technology is an increasingly widely used technology in the field of high-end motors in recent years, which can improve the heat dissipation performance and dust-proof sealing performance of the motor stator. However, the quality of the stator potting depends on the characteristics of the potting compound itself (thermal conductivity, insulation grade, viscosity, strength after curing, etc.) on the one hand, and on the potting device and potting process on the other hand. There are two main types of potting glue: epoxy resin and silicone. Silicone potting adhesives have high thermal conductivity, but high viscosity and low strength after curing. Therefore, epoxy resin potting adhesives are more commonly used motor potting adhesives. As the t...
