Do you know the key to the durability of the inner rotor fan

The key points for the durability of the inner rotor fan mainly include the following: 1. Comparison of impeller materials: Galvanized sheet impellers have strong corrosion resistance and are suitable for humid environments. Aluminum alloy impellers are lightweight but need to be protected from high-temperature deformation. 2. Bearing and motor lifespan: Imported bearings (such as TPI) have a long lifespan. For domestic substitutes, attention should be paid to the temperature rise test data. 3. Protective design: The fully enclosed honeycomb structure motor is dust-proof and moisture-proof, suitable for dust-prone workshops or coastal areas.
