In the design of refrigerator shaded pole motors, the selection of insulation materials and temperature conduction control are crucial key points. The following are the relevant points:

Insulation material selection:

1. High temperature insulation performance: The refrigerator shaded pole motor will generate a certain amount of heat during operation, so the insulation material needs to have good high temperature insulation performance to prevent electrical short circuit or leakage between the motor components and other components or external structures.

2. Insulation strength and withstand voltage: The insulation material should have sufficient insulation strength and withstand voltage to ensure that the motor will not be electrically broken down or damaged during normal operation.

3. Moisture resistance and corrosion resistance: Since the refrigerator environment may have temperature and humidity conditions, the insulation material needs to have good moisture resistance and corrosion resistance to maintain its insulation performance and reliability.

4. Insulation material selection: Common insulation materials include insulating paint, insulating paper, insulating tape, insulating plastic, etc. According to specific requirements and application scenarios, manufacturers will select suitable insulation materials for use.

Temperature conduction control:

1. Component design: The refrigerator shaded pole motor will generate heat during operation, so an effective heat dissipation design is required to keep the motor temperature within an acceptable range. Heat dissipation design can include components such as heat sinks, heat pipes or fans to increase the heat dissipation surface area or provide forced air cooling.

2. Heat conduction materials: On key components of the motor, such as motor windings and motor chips, materials with high heat conduction properties, such as thermal paste or thermal conductive glue, can be used to improve the heat conduction efficiency and reduce the temperature.

3. Temperature sensor and control: Installing a temperature sensor can monitor the temperature of the motor in real time and control the temperature and adjust it through the control system. This ensures that the motor operates stably within a safe temperature range.

4. Optimizing the motor structure: By optimizing the structural design of the motor, such as improving the heat dissipation channel and increasing the number of heat sinks, the heat dissipation effect of the motor can be improved and the temperature can be reduced.

The key point of temperature conduction control in the selection of insulation materials is to ensure that the refrigerator shaded pole motor has good insulation performance within the operating temperature range, while effectively managing the temperature of the control motor to ensure the safety, reliability and performance stability of the motor. These points need to be comprehensively considered and designed according to specific product requirements and application conditions.
