[0002] Traditional AC fans use AC motors. However, AC motors usually require higher energy when running, which leads to energy waste. In order to improve the energy efficiency of fans, DC motors become a more suitable choice because they are usually more efficient than AC motors. DC motors have higher energy utilization than traditional AC motors, so they become an ideal choice for manufacturing environmentally friendly fans. DC motors can control the speed and operation mode more flexibly, which provides more functionality and customizability for fans. Through appropriate electronic control, DC motors can achieve a variety of operation modes, such as timed shutdown and reverse operation, so as to meet consumers' different needs for fan functions.
