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%.
We have developed into expert in many areas, we have self-developed home appliances included Juicer, Blender, Hand mixer, and Garden tools production, Ventilated fan motor.
