The selection of sealing materials is crucial for the performance and reliability of products in the manufacturing process of modern motors and automotive electronics. Especially when facing harsh working conditions such as high temperature, vibration, moisture, solvents, and long-term operation, choosing a suitable sealing adhesive is particularly important. The Yilian EP 2025 series epoxy potting material, with its excellent performance, has been successfully applied to the potting protection of disc motor stators, solving the problem of motor protection for customers in high temperature environments.
A certain customer is developing a disc motor and needs to seal the stator of the motor to ensure that it can work stably for a long time in high temperature environments. After multiple experiments and material selection, the customer has decided to use the Yilian EP 2025 series epoxy potting material as the potting material for this project.
Customer demand
The stator of the disc motor of this customer needs to withstand high temperature environments during use, especially under high loads, and the working temperature of the motor can reach 150 ° C. In order to ensure that the motor does not malfunction at high temperatures and maintains good performance, customers have very strict requirements for sealing materials. The specific requirements are as follows:
High temperature tolerance: The material is required to maintain stable performance at a high temperature of 150 ° C.
Good adhesion and crack resistance: The sealing material should be able to tightly adhere to the surface of the motor stator to prevent cracks caused by thermal expansion differences.
High thermal conductivity: The motor generates a large amount of heat during operation, and the material needs to have good thermal conductivity to ensure rapid heat dissipation and avoid overheating.
Excellent electrical insulation: The motor stator requires efficient electrical insulation performance to prevent safety issues such as short circuits.
Chemical resistance: The material must be able to resist chemicals such as oil and solvents that may come into contact with the motor during operation.
Long term stability: The long-term performance of the material must be reliable and not affected by the environment.
