With the increasing development of electronic products, electromagnets, as important electrical components, have been widely used in many industries, especially in high-precision control, automation equipment, and power tools. However, electromagnets are subject to factors such as temperature rise, mechanical vibration, and environmental moisture during operation, which puts higher demands on their performance stability and service life. The selection of thermal conductive sealing materials is crucial to ensure the long-term reliable operation of the electromagnet.
Electromagnets are often exposed to external vibrations, impacts, and extreme environmental conditions during operation, which puts higher demands on their long-term stability and mechanical strength. In order to ensure the continuous and efficient operation of the electromagnet, it is necessary to use sealing materials with excellent thermal conductivity, high hardness, good toughness, and temperature resistance to protect its internal components and effectively disperse the generated heat.
Challenge: Heat dissipation problem of electromagnet in high temperature environment
Requirements for thermal conductivity
The working environment of an electromagnet usually requires it to be able to quickly and effectively conduct heat from the inside to the outside. If the heat cannot be carried away in a timely manner, the temperature of the electromagnet will rapidly rise, affecting its normal operation and even causing malfunctions. The thermal conductivity of the sealing material must meet specific requirements to ensure that the electromagnet can operate stably for a long time.

Overheating risk and thermal management issues
Electromagnets generate a large amount of heat during long-term operation. If the heat cannot be effectively dissipated, it may cause the temperature of the electromagnet to be too high, thereby affecting the stability of its magnetic field and even causing damage to the internal components of the electromagnet. Especially in high load operating scenarios such as automation control equipment and power tools, electromagnets need to be able to maintain stable temperature and performance for a long time.
The impact of vibration and shock on electromagnets
Electromagnets not only have to withstand continuous high temperature loads, but may also face vibrations and external impacts from equipment operation. These external forces pose a challenge to the stability of the electromagnetic structure. How to choose a sealing material with high hardness and resistance to mechanical impact has become another difficulty in designing electromagnets.
Long term stability and performance degradation issues
The long-term stability of the sealing material of an electromagnet is crucial when operating in extreme environments. If the sealing material undergoes hardness changes, cracking, aging, and other phenomena after long-term use, it will directly affect the performance of the electromagnet and even lead to premature failure. Therefore, choosing a sealing material that can maintain stable performance in high temperature, vibration, and aging environments is the key to ensuring the reliability of the electromagnet.
