How to distinguish the fan motor is good or bad
 
In order to help buyers to improve the ability to identify, is now offering a few simple identification method for reference:
 
1 weigh the weight, the weight ratio of inferior products with the specifications of the formal product of light 30%-50%.
 
2 with the hand motor front bearing temperature rise. Because the motor outside the plastic cover, the cover is opened does not touch the temperature rise of the motor, and short running temperature rise is not obvious. Can be two sets of products with the specifications of the relative distance of 1-1.5 meters, so that at the same time in the high gear operation, due to the two fan of the wind direction in the opposite direction, the damping effect is greatly increased, the motor is easy to heat. After the end of the machine down with a finger to touch the motor temperature rise, poor electric fan temperature rise is very obvious.
 
3 resistance measurement: will use multimeter with friends can Nawan table resistance measurement electric fan plug at both ends of the inferior product line diameter and the number of turns, the resistance ratio high quality products 15-20%.
怎样简单辨别风扇电机的好坏
为了帮助购买者提高鉴别能力,现提供几种简单的判别方法供参考:
1.掂量整机的重量,劣质产品的重量比同规格的正规产品轻30%-50%。
2.用手摸电机前端轴承的温升。由于电机外部有塑料罩壳,不揭开罩子是摸不到电机温升的,况且短时间运行温升不会很明显。可将两台同规格的产品相对距离1-1.5米,使其同时在高挡运行,由于两台电风扇的风力旋转方向相反,阻尼作用大大增加,电机就容易发热。停机后用手指摸电机前端轴承温升,劣质电风扇温升非常明显。
3.测电阻:会使用万用表的朋友可以拿万用表测电风扇插头两端的电阻,劣质产品线径细、匝数多,电阻比优质产品高15-20%。
