Q:Why does the fan seem to spin backwards when it spins?
This is the reason that the wheel looks stationary, when the frequency of the fan's rotation is related to the maximum frequency that the human eye can tell
Q:Is the power consumption the same when the fan is used in different gears?
Asynchronous motor efficiency is a very delicate thing, when the speed is similar to the design speed, the efficiency is very high, when the deviation is large, the efficiency is very low. Therefore, the speed range of the general fan is also very small
Q:How is the fan made up?
he main components of the electric fan are: AC motor. Its working principle is: the coil in the magnetic field force and rotation. Electrical energy is converted to mechanical energy, and, at the same time, due to coil resistance, it is inevitable that some of the electrical energy is converted into heat energy.
Q:What is the difference between air conditioner speed regulation and electric fan speed regulation?
Variable frequency air conditioning is to change the frequency of motor power supply to achieve speed regulation, in fact, the frequency adjustment will also change the voltage.
Q:What is the principle of an automatic fan head swing back and forth?
The second is to rely on the synchronous motor (with reducer) of the electric fan head swinging, rotating direction of synchronous motor is random, when the resistance will automatically change the direction of rotation, when the swing head to set the position of the synchronous motor will be blocked after back, thus forming a pendulum head phenomenon.
Q:What is the problem of slow fan speed?
It should be the oil, or the motor is damp
Q:What are the advantages and disadvantages of the vaneless fan?
The base of a fan without leaves determines that the diameter of the fan blades inside it is usually small, so that the same amount of air as the ordinary fan must be made to turn the blade faster, so the noise will be greater
Q:How much electricity does the ordinary fan use in a day?
If the fan power is 40 watts / hour, then use 0.94 kwh 24 hours a day
Q:When did the electric fan start to appear?
25 years later, Ecclestone engine and electrical company in the United States, and developed the world's first electric fan gear driven around the head
Q:How to pick an electric fan?
The advantage of the large fan is that the fan blade is long and the radiating area is large, so the gas flow rate is larger. But if not properly designed, the cooling capacity of a large fan may not be as good as that of a small fan
