Q:Why does the electric fan always rotate clockwise?
The fan blade of a conventional fan has a tilt angle (the steering is designed from the angle of the tilt angle). The motor causes the fan to rotate and the space-time is compressed, causing air flow (resulting in wind). The direction of flow is related to the direction of the fan's rotation and the inclination of the fan blade.
Q:What is the difference between the natural wind and the sleeping wind?
The fan blows for half an hour before the natural wind, and then for half an hour, medium natural wind, and finally blow down the natural wind to the set time
Q:Why does the fan seem to spin backwards when it spins?
Because the human eye to object displacement to distinguish between 0.1s, and 0.1s when the fan turn fast may turn 350 degrees, looks like reversal of 10 degrees, so add up, like upside down
Q:What are your misunderstanding blowing ？
That is to use electric fans to cool down and sleep together. When sleeping, the functions of the organs in the body are reduced to the lowest level. All reflexes disappear, immunity declines and diseases are easily induced
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:What's the effect of the air circulation fan?
In the case of air circulation fan, no need for air conditioning, nor the same as ordinary fans blowing uncomfortable, completely feel the wind blowing
Q:How long can the electric fan be timed?
One is mechanical timer, and the other one is spring. At most, it can be fixed for one hour
Q:Which items should we pay attention to selecting electric fans?
Choose the electric fan to regard decoration has no damage; net cover before and after anastomosis closely, no deformation, mesh wire joints loose desoldering etc.. Flexible lifting fan.
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:How to pick an electric fan?
The fan leaves of a bamboo, streamlined appearance.
