عربىThe motor can be compared to the heart of the range hood. The suction power of the range hood, the intensity of the noise, and the life span of the range hood are all closely related to the motor. Therefore, the quality of the motor directly affects the overall quality of the range hood. Therefore It is crucial for us to understand the quality of motors.
A good motor not only has a long life but also is not prone to decay. Many friends here will ask, what is attenuation? Attenuation means that for example, when you buy a new cigarette machine, basically any oil smoke can be sucked away at that time, and the suction rate is very high. However, after a few years, under normal maintenance and use, the motor's suction rate slowly decreases. , this is attenuation.
You can judge from the following points:
1. Whether it is fully enclosed
Now there are two types of motor casings, one is the fully enclosed type as shown on the left in the picture above, and the other is the semi-enclosed type as shown in the right picture. The dust-proof performance of the fully enclosed motor is much better, while the semi-enclosed type produces less oil fumes. After breaking in, sludge will easily breed, which will reduce the motor speed over time, increase the noise, and shorten the service life. The cost of semi-enclosed motors is lower. Only some very cheap hoods are still in use. Most hoods already use fully enclosed motors.
2. Number of stacks of motor copper wires
Many friends don’t know much about this. We all know that the motor is divided into a rotor and a stator. The rotor is the rotating part in the middle, and the stator is the part that generates a rotating magnetic field around the rotor cylinder. We can see that there are many turns of pure enameled copper wire on the stator. The copper wire is wrapped around the silicon steel stator core in many groups. This number of groups is the number of stacks of the motor.
Ordinary motors have 16 or 20 sets of coils. Good motors use 24, 28, or 32 sets of coils. The more coils, the more stable the speed and the lower the temperature generated, because the heat generation is small. Longer life.
3. Winding coil
Today's motors are basically pure copper enameled wire, with copper wire inside and an insulating enameled layer on the surface. Therefore, the higher the purity of the copper wire, the stronger the conductivity, the better the heat dissipation capacity, and the longer the life...
4. Bearings
The pin part of the bearing connecting the rotor is a total of two bearings. The quality of the bearing will also determine the quality of the motor. For example, many big brands now use Japanese NSK double ball bearings. NSK is a brand of bearings that is very famous in the industry.
They are all sealed bearings, which are filled with grease before leaving the factory. It can be used for a long time, there will be no shortage of grease, and oil fumes will not escape. As for inferior bearings, if they are used for a period of time, the grease inside will decrease, which will cause the speed to drop, the temperature to rise, and in severe cases, the motor may be burned.
5. Whether with temperature control?
Temperature control is very important in motors. Some small manufacturers consider that household fumes will not cause stalling. Like large industrial and mining enterprises, motors must have temperature control because their motors are very expensive. If stalling occurs, the internal temperature will drop instantly. It will be very high and can easily burn out the motor.
Therefore, some small brand manufacturers consider that this situation should not happen, so they use cheap motors without temperature control. If there is no problem, it is fine, but if there is a problem, the motor will be burned. For motors with temperature control, when a problem occurs, the power supply is cut off, thus protecting the motor.
The special motor for the Mido range hood adopts a fully enclosed 32-stack fully enclosed motor with outstanding capabilities to protect the kitchen, make the oil fume obedient, and create a fresh environment in the kitchen. It will bring you a different kitchen performance and enjoy technological cooking.
