According to the structure of the motor, it can be divided into: single-phase capacitor type, single-phase shaded pole type, three-phase induction type, DC and AC/DC dual-purpose series commutator type, DC permanent magnet, DC brushless electric fan.
According to the purpose of classification, it can be divided into: household electric fans and industrial exhaust fans.
According to the classification of incoming and outgoing wind, it can be divided into: axial fan, centrifugal fan and cross-flow fan.
⑴Household fans: there are ceiling fans, table fans, floor fans, wall fans, ceiling fans, ventilating fans, turning fans, air conditioning fans (ie cold fans), etc.; table fans can be divided into shaking and non-shaking. The page turning fan; among the floor fans are those that shake their heads and turn pages. There is also a small breeze fan, which is specially hung in a mosquito net. When you go to bed at night in summer, it will be breezy when you turn it on, so you can sleep peacefully without getting sick. Warm reminder, the fan is easy to adhere to dust in the air, so it is better to cut off the power and clean it in the process of use.
⑵ Industrial exhaust fan: mainly used for forced air convection. After the electric fan is used for a long time, it is easy to get a lot of dust under the fan blade. This is caused by the fact that the fan blades are charged with static electricity due to the friction between the fan blades and the air when the electric fan is working, and the charged objects can attract light and small objects, thereby being able to absorb the fine dust floating in the room.
