The motor is the core component of the household range hood, and the quality of it has a great impact on the suction, noise and life of the range hood.
In the face of the dazzling range of high, medium and low-end retail prices of range hoods in the market, consumers are dazzled. Because of their unprofessionalism, they sometimes mistakenly think that they are all the same products because of their appearance, and choose inferior or low-quality products, which leads to safety and other issues. risk.
First, the types of motors: There are mainly two types of fully enclosed and semi-enclosed motors on the market. It is better to choose fully enclosed motors than semi-enclosed motors. The reason is that during the use of the range hood, the oil fume will enter the inside of the motor, which will cause certain damage to the motor. The fully enclosed motor plays a protective role.
If subdivided according to material, it can be divided into all-copper wire motor, all-aluminum wire motor, and even copper-clad aluminum wire motor in the market, and all-copper fully enclosed bearing double ball motor is the most popular motor, and regular manufacturers are in Use such a motor.
Second, the number of motor stacks: the number of motor stacks refers to the number of rotors. The higher the number of motor stacks, the larger the volume of rotors, the better the performance of the motor, and the better the smoke exhaust effect.
At present, 16, 18, 20, 24, 28, 32, 36 stacked motors, 24 and 28 motors are commonly used on the market, and 32 and 36 are relatively rarely used.
Third, the motor winding: the material of the winding is also very important. At present, the best material is pure copper wire. The higher the purity of the copper wire, the stronger the electrical conductivity and the good heat dissipation capacity, so the suction of the range hood is very good. It is bigger, and the noise is also very small.
Fourth, motor bearings: Bearings are also a standard to measure the quality of a motor. It is best to choose bearings with balls, quietness, and imported bearings. At present, Japan's NSK bearings are the best, quiet, stable, and first- and second-tier brands. All use this kind of bearing, you need to pay special attention when purchasing.
Fifth, motor material: the material of motor manufacturing also needs our attention. At present, the best steel plate material is cold-rolled steel plate, but generally the specific material of the steel plate is not introduced to consumers, so consumers cannot know the steel plate. specific material.
