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

Q: How long can the electric fan be timed?: Another is circuit control, can be 30 minutes, 1 hours, two hours, four hours, and so on, depending on the circuit, microcontroller, timer settings

Q: What's the difference between a cool fan and an electric fan?: The principle of an air conditioner fan is the same as that of a fan. It speeds up the flow of air in the room. But it is just letting the water or ice add to it. This makes the weather more uncomfortable

Q: How to measure the quality of fan motors with digital multimeter?: In the multimeter stalls placed in the 20M file, measuring winding (using the motor three lines in any one) and the motor stator core insulation resistance, the resistance should be above 2M, can determine the motor only problem

Q: What is the difference between air conditioner speed regulation and electric fan speed regulation?: The difference between them is reflected in the range of speed regulation with a fixed torque load. Two, the motor efficiency is reflected at different speeds. Three, the torque is expressed at different speeds.

Q: What is the principle of a vaneless fan?: The base there is a similar air compressor device, the air is sucked in, after compressed by spraying out annular gap above the ejected air annular air flow driven device, has the wind.

Q: What is the problem of slow fan speed?: The capacitive value of the starting capacitor is caused by a decrease in the capacitance

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: How to measure the speed of an electric fan conveniently and precisely?: Assemble the light sensor, then calculate the frequency and calculate the speed after the fan number

Q: How do you use an electric fan to set up an air distribution system in an air tight room?: In the absence of outdoor airflow, the warm air is lighter than the cold air. From a hydrostatic point of view, the temperature difference brings air stratification in the vertical direction
