The choice of direct current is better. First of all, the AC motor has a simple structure, easy to manufacture, and low cost. However, AC motors usually require the use of capacitors or inductors to change the current direction, which can cause power loss, overheating, noise and other problems. These problems will affect the use of hair dryer experience, especially in the high-end hair dryer is more obvious. In addition, the electronic frequency converter of AC motor will also bring high-frequency electromagnetic radiation, which will have an impact on human health.
In contrast, DC motors can effectively solve these problems. DC motor speed stability, noise, long life. Secondly, the DC motor can directly control the current direction through the semiconductor components, without the need to use capacitors or inductors to change the current direction, less power loss, less heat, can be more energy-saving. In addition, the electromagnetic radiation generated by the electronic inverter of the DC motor is also much smaller than that of the AC motor, and the impact on human health is relatively small.
In general, from the performance, efficiency, life, noise, heat and other aspects of consideration, DC motor is a better choice. It is recommended that you should choose to use DC motor products when buying hair dryers, which can ensure better use and longer service life. At the same time, in the repair and maintenance of hair dryers, it is also necessary to pay more attention to the maintenance and maintenance of DC motors, such as regular cleaning and keeping dry.
