Nowadays, the number of Internet celebrity hair dryers is gradually increasing, and they are becoming more and more intelligent. Compared with the old hair dryers before, the experiential effect is better. Many friends do not understand the basic working principle of the hair dryer, and do not know what motor it uses. The following is a brief introduction to Chaojun Transmission, and I hope it can help you!
Most of today's hair dryers use high-speed DC brushless motors. The basic working principle is to use the interaction between the electric fan and the heating coil to convert electrical energy into convective heat energy. After the fan rotates continuously, the airflow generated flows to the hair dryer through the heating element. As the air flows over the heating coil, the heat of the coil heats the air flow due to forced convection, and the hot air exits the end of the blower.
The function of the high-speed brushless DC motor in the hair dryer:
1. Safety protection system. In order to avoid overheating and fire, the high-speed brushless DC motor has an overheating protection device. When the temperature and current are high, the fuse will melt and the power will be cut off, and it will automatically play a protective role.
2. The high-speed brushless DC motor has a leakage protector, real-time monitoring, and the circuit will be automatically cut off if there is leakage.
3. The shell of the hair dryer is insulated with PP and ABS plastic materials, which has good heat insulation function; the high-speed brushless DC motor runs stably and reduces heat generation.
4. The decibel of the high-speed hair dryer is as low as 45db, the noise of the fan is as low as 40db, the noise pollution is small, and the damage to the ears is reduced.
Why does the high-speed hair dryer use the brushless DC motor developed by Chaojun Transmission? The above briefly explains the basic working principle and function. I hope it can help everyone!
