Electric fan is a motor to drive the blades rotating, accelerated flow, to improve human body heat with the ambient air conditions, cool the purpose of effective ventilation.
According to the structure can be divided into household electric fan fan, ceiling fan, exhaust fan, pp fan, appeared in recent years, air-conditioning fans (i.e., air cooling fan), etc. With no wind to Dyson, developed in recent years hakaze fan, also will be blossoming in China. Application of electronic technology and microcomputer technology, and many electric fans to develop in the direction of multi-function, comfort and luxury, but its main power of the motor will be the most important, throughout the domestic and international calls for energy conservation and emissions reduction of brushless motor in the future in the field of electric fan will be replaced by other motor, fan drive will become the mainstream
Desk fan and ceiling fans with motors
Fan with motor more single-phase capacitor motor operation, the input power is 32 ~ 85 w. To reduce cost, and the wind leaf diameter is a small desk fan and useful single-phase asynchronous motor.
In order to meet people's comfort requirements, adopt reactor, winding shaft head of the motor and speed control, such as electronic circuit.
Ceiling fan with motor single-phase capacitor motor operation, fully enclosed outside substructure, the input power is 75 ~ 100 w. The number of the motor is 14, 16 or 18, speed is slow, to achieve security purposes. Motor adopts multiple tap reactor and switch speed.
Turn to page fan motor
Turn the fan fan page generally adopts single-phase capacitor running motor drive, usually use tap to adjust. Turn to page before the fan blades of louver guide wheel (grating), using the guide the rotation of the rotor and change the direction of the wind with the wind. The guide wheel by the single-phase permanent magnet synchronous motor drive after reduction.
Air-conditioning fans (air cooling fan) with motor
This fan is lower than ordinary fan blow out air temperature. Its principle is that the cover of single-phase asynchronous motor or single-phase permanent magnet synchronous motor drives the water (or ice) curtain slowly moving up and down the rolling, driven by single-phase capacitor running motor fan is the water curtain around a certain humidity of air blowing out, the cold air in the hot days make people comfortable. The climate is dry, blow out the significant effect of the cold wind, with a certain humidity, and purifying the air.
Warm wind for motor
Warm wind, also known as hot air, indoor air while working in the fan behind and the electric heating element blown out after heating, heating.
Fan motors with single phase mask processing of step motor, general power rating for the 25 ~ 40 w.
Some heaters installed at the bottom of the single-phase permanent magnet synchronous motor with reducer, restore about heater for reciprocating (back Angle 80 ° ~ 90 °), suitable for people or a wide range of heating.
