The working principle of a hair dryer: An electric fan and a heating coil are used to convert electrical energy into convective heat. The rotation of the fan generates air flow through the heating element to reach the hair dryer. When air flows through the heating coil, the heat of the coil heats the air flow due to forced convection, and hot air flows out from the end of the hair dryer.

What kind of motor is better? It is recommended to use a high-speed DC brushless motor, which has relatively high performance and the following characteristics:


1. The safety protection system can better prevent the danger of overheating and fire. When the temperature and current are too high, the fuse will automatically melt and the power supply will be cut off.

2. The leakage protector of a high-speed brushless DC motor will automatically cut off the circuit if it detects current leakage.

3. Insulation function. Without appropriate insulation measures, the shell of the hair dryer will become very hot. The high-speed DC brushless motor operates stably to reduce heat generation. The fan shell is insulated with PP and ABS plastic materials.

4. Using a high-speed DC brushless motor, the decibel is as low as 45dB, and coupled with a fan noise isolation structure, the total noise is as low as 40dB, greatly reducing noise pollution.
