1.Fan

Taking into account the characteristics of the rotation balance, the number of fan blades is an odd number, even if the rotation of the blade is prone to resonance, resulting in damage. The original fans are basically three, in recent years there has been a lot of five fan, this is because the fan blade number, wind cut is more uniform, also more gentle.
The number of fan blade wind cutting more intensive, more gentle wind effect, air flow is more stable, generally five blade blade diameter than the three leaf, and three leaf blade twist angle of more than five, so the five blades in the air, soft wind effect, wind speed, wind wind leaf the effect is hard.
2.Motor material
Is the core component of the motor movement movement, there are many kinds of materials, and the market the most used materials: copper core, copper clad aluminum and aluminum wire core core. Copper core permeability is highest, and the attenuation coefficient is small, the longest and most expensive; secondly, copper clad aluminum, aluminum wire motor again.
3.Capacitor configuration
As an important component of capacitor fan, can reflect the advantages and disadvantages of the motor from the side, the capacitance of general household electric fan is smaller, indicating the motor starting current is smaller, more energy saving, the performance of the motor is relatively stable; the rated voltage value is bigger, stronger ability of withstanding voltage impulse capacitor, motor performance will be more stable.
4.Gear setting and control
At the time of purchase, users also need to pay attention to the electric fan gear set, multi gear can provide a variety of air and a variety of modes, to more users. Handling, a lot of machines with remote control or can be connected to the phone to control, lying on the bed can be controlled, relatively convenient.
5.Electric fan head shaking mode
The electric fan head determines the fan, general electric fan is divided into upper and lower, manual, pitching, shaking the head, 360 degrees O and eight words shook his head, shook his head and shook his head, of which eight have dual connecting rod and double head motor / drive that three head, belongs to the high end of the machine, give relative decent, but more likely to have problems more! The most practical or ordinary shaking head electric fan.
Head shaking way can be selected according to the demand, if the use of the crowd would prefer to choose the left or right side of the head, if you need to adjust the temperature of the air conditioning, promote the air cycle should choose 360 degrees or O word head.

1.扇叶
    考虑到旋转平衡的特性,一般电风扇的扇叶数量都是奇数的,偶数叶片在旋转时容易产生共振,造成损坏。原本电扇基本都是三叶,最近几年出现了很多五叶风扇,这是因为风扇扇叶数量越多,风被切割的就更均匀,也就更柔和。
  风扇叶片数越多切风越密集,风效更柔和,风量更稳定,一般五风叶的风叶内径要比三风叶的大,而三风叶的扭角度比五风叶的大,故五风叶的风量大、风效柔和,三风叶风速大、风效较硬。
 
2.电机材质
  电机的核心部件就是机芯,机芯材料有很多种,而市面上用的最多的材料有:纯铜机芯、铜包铝机芯及铝线机芯。纯铜机芯导磁率最高,且衰减系数小,寿命最长、造价最贵;其次铜包铝,再次铝线电机。
 
3.电容配置
  电容作为风扇的重要部件,可以从侧面反映电机的优劣,一般情况家用电风扇的电容量值越小,说明电机启动电流越小,越节能,电机的性能相对越稳定;另外额定电压值越大,电容的耐电压冲击能力越强,电机性能相对会更稳定。
 
4.档位设置以及操控性
  在购买时,用户还需要关注电风扇的档位设置,多档位能提供多种风量以及多种模式选择,适应的用户更多。操控性来说,很多机器带有遥控或可连接手机进行操控,躺在床上就能控制,相对来说方便很多。
 
5.电风扇摇头方式
  电风扇的摇头决定了风扇送风范围,一般电风扇摇头分为上下、手动、俯仰、左右摇头、360度摇头、O字摇头以及八字摇头,其中八字摇头有双连接杆和双电机/三电即驱动带动摇头,一般属于高端机,送人相对比较体面,但是功能越多出问题的几率越大!实用性最强的还是普通摇头电风扇。
  摇头方式可以根据需求选择,如果使用人群广就要优先选择左右摇头功能,如果需要调节空调温度,促进空气循环就应当选择360度或O字摇头。
