Heating is an important aspect of the safety assessment of power tools. Power tools are composed of shell, motor, transmission mechanism, working head, handle, power switch and power connection components, among which the motor is the core part. The motor will generate losses during operation. On the one hand, these losses affect the operating efficiency of the motor, and on the other hand, the motor heats up and the temperature rises. If the temperature of the motor is too high, the insulating material will age faster, resulting in a decrease in the insulation performance, and even burn out the motor in severe cases. Therefore, the heating problem is directly related to the service life of the motor and the reliability of its operation. Thermally conductive potting compounds can be used to seal winding coils and protect components from shock, vibration, thermal shock, moisture and dust.

As electronic products become more and more intelligent and diversified, the requirements for product performance and safety are getting higher and higher. In response to these requirements, the demand for electronic components is becoming more and more high-end and more. Many electronic components such as motor driver chips, controller chips, and MOSFETs are used in power tools, which brings many heat dissipation problems. Thermal interface materials (Tgard series thermally conductive insulating sheets, HD90000 thermally conductive silicone sheets, Tgrease2500 thermally conductive silicone grease) can be used to help efficiently transfer heat.
