电风扇是通过控制系统来控制电机,并带动扇叶高速旋转,强制空气流动,来改善人体和周围空气的热交换条件的。随着电子技术的发展,可使电扇带有模拟自然风的性能,使人们更感舒适。今后还将有少量高档电子遥控微电脑风扇问世。风扇材料也有从金属件向塑料件发展的趋势。电风扇种类及结构特点按电动机分类有:单相罩极式感应电动机风扇;单相电容运转式
Electric fans control the motor through the control system and drive the blades to rotate at high speed to force the air flow to improve the heat exchange conditions between the human body and the surrounding air. With the development of electronic technology, fans can simulate the natural wind performance, make people feel more comfortable. In the future there will be a small amount of high-end electronic remote control microcomputer fan come out. Fan materials also have a tendency to develop from metal parts to plastic parts. Fan types and structural characteristics by motor classification are: single-phase shaded pole induction motor fan; single-phase capacitor operation
