Hair dryers are mainly used for hair drying and styling, but they can also be used for local drying, heating and physical therapy in laboratories, physical therapy rooms, industrial production and artistic design.

According to the type of motor used, hair dryers can be divided into AC series excitation type, AC hood type and DC permanent magnet type.

The advantages of AC series excitation hair dryer are large starting torque and high rotating speed, which is suitable for manufacturing high-power hair dryers. The disadvantage is that the noise is high, and the commutator has certain interference to telecommunication equipment.

The advantages of AC hood blower are low noise, long service life and no interference with telecommunication equipment. Disadvantages are slow speed, poor starting performance and heavy weight.

The advantages of DC permanent magnet hair dryer are light weight, high rotating speed, simple manufacturing process, low cost, good quality and low price. The disadvantage is short service life.
