Core configuration of range hood - interpretation of basic knowledge of motor First, the core technology configuration of range hood products. The most important part of human beings is the heart and brain , and the heart of the car is the engine. Therefore, the core of the range hood is the motor, and the quality of the motor determines the quality of the range hood. The switch is the brain (central nerve) of the range hood. Stator - pure copper wire motor, copper clad aluminum wire motor, aluminum wire motor rotor - cast aluminum rotor bearing - double ball, single ball, oil (powder) shell aluminum shell, iron shell stator core - silicon steel sheet, Stack thickness ( 18 , 20 , 24 , 26 , 28 , 30 , 32 ) Â Protection device - double thermostat, disposable thermostat. three, Â The main factors affecting the quality of the range hood motor: 1 , Â Motor temperature rise 2 , Â Enameled wire quality: 3 , bearing quality 5. Is the power of the range hood as high as possible? There is no direct correlation between the input power and the exhaust volume of the hood. The most direct impact on the exhaust volume is the output power of the motor itself. The greater the output power, the greater the strength of the motor and the faster the speed. The input power marked by the hood is not the same as the actual output power of the motor. This is because international regulations: the power of the range hood motor can not be greater than 120% of the nominal value, and there is no regulation can not be less than a small amount, for example, a 100W motor marked 280W is also qualified. This is why some manufacturers have exploited the loopholes, deliberately marking high power, so that consumers mistakenly believe that their hoods have high power and good performance, misleading consumers. Therefore, you can't judge the performance of the product just by the power of the product. At the same time, it is necessary to refer to the air volume and wind pressure parameters of the product identification. Therefore, the current hood power rating on the market is also confusing. Therefore, determining the suction of the range hood is determined by the power of the motor itself, not by the power of the label. Fourth, the range hood motor failure and solution V. Analysis of the circulation of the hood motor market The cost of copper wire motor is more than double that of aluminum wire motor. At present, the reason why the Chinese hood is widely used in the third- and fourth-tier market is very cheap. The reason why it is cheap is to use the lowest cost and short life aluminum. Line motors and other low-end inexpensive configurations. Many of the prefecture-level market markets also widely distribute such products, and even some manufacturers use copper-clad aluminum wire motors to replenish them in order to make profits.

Second, the basic structure of the range hood motor:
- National standard 90K , internal control temperature rises within 75K . It is related to wind turbines, wind cabinets and air ducts.
Must pass the turn-to-turn insulation test. Motor that does not pass the turn-to-turn insulation test is easy  Short circuit, weakness.
- Currently NSK and NTN in Japan are of the highest quality. Domestic bearings have matured and are currently using domestic bearings. Oily (powder) bearings have a short life.
