The motors of ordinary hair dryers are mainly turbines or fans, and their rotation speeds are generally relatively slow, resulting in low wind speeds and long hair drying times. They can only "bake" dry the hair by increasing the temperature, which is very easy to burn the scalp, cause the hair to dry, and the hair quality will become worse over time. In contrast, the high-speed brushless motors used in high-speed hair dryers have ultra-high rotation speeds, achieving higher wind speeds and larger air volumes, and doubling the efficiency of drying hair. However, they also have the disadvantage of high wind noise caused by high wind speeds. Moreover, in order to better meet the assembly requirements of the heating rack in the high-speed blower, the air duct assembly needs to be made of expensive high-temperature resistant materials as a whole, increasing the production and manufacturing costs.
