As we know, NAKKA is specialized in dc fans, mainly around commercial fans, industiral fans, and drum fans. Dc fans are the advanced fan products booming in the recent years. However, people just know its name but have no specific ideas of it. In today’s news, we are going to introduce what is dc fans actually.
Dc fans can be called as EC fans. Dc fans is using dc motor which relies on permanent magnet. Fan motor consists of rotor and stator. The rotor of AC motor is iron. On the contrary, rotor of DC motor is magnet. Therefore, when the DC motor is energized, electric power will push stator spin, and according to magnet effect, stator will help the rotor spin. Compared with the AC motor, stator of AC motor is iron so that stator and rotor need electrical power to move. Here is the biggest difference of AC fans and DC fans from the fan motor.
Based on the message I mentioned above, we can conclude some advantages of DC fans.
Due to rotor doesn’t need electrical power, so that DC fans save more energy than AC fans. A 90w dc fan is equal to a 180w ac fan.
What’s more, dc fans are low noise, have a long service life, and have multiple functions than AC fans. You are warmly welcome to see our hot selling products.
