Q:How is the fan made up?
The control circuit is made of IC induction magnet, and the N.S. pole controls the coil through the circuit to generate internal excitation to rotate the rotor.
Q:What are the common faults of electric fans?
If it is due to electrical fault, you can check the wiring of the wiring, and sometimes wire damage, etc., can be repaired on the problem.
Q:What is the function of the fan blade?
Most of the fans are three blades. In addition, the three blades have better dynamic balance, not easy to oscillate, thus reducing the wear of the bearings, prolonging the service life and reducing the maintenance cost
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:What is an electric fan?
The energized coil rotates under the force of the magnetic field. 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:How was the electric fan invented?
The mechanical fan originated in 1830, an American named James Byron inspired by the structure of clocks and watches, invented a mechanical fan that can be fixed on the ceiling and driven by a spring
Q:What is the working principle of an electric fan?
When the electric fan works, because the electric current passes through the coil of the fan, the wire is provided with resistance, so it will inevitably generate heat and release heat outwards, and the temperature will rise naturally.
Q:Fans can shake their heads, but fan leaves do not turn, where is the reason?
Most of the motor burn is accompanied by lack of oil in main shaft.
Q:What's the difference between a cool fan and an electric fan?
Cold fan, commonly known as air conditioning fan, and it is different from the ordinary fan: the cold fan to add water, blowing the wind is cold air, containing water, it is equivalent to a small power water air-conditioning. In addition, the application of cold fans and ordinary fans is also quite different.
Q:Why not head fan to blow?
The blower is suitable for choosing the head. If the fan blows directly to the head and neck, the scalp temperature drops, the reflex causes the contraction of the cerebral blood vessels, and the brain blood flow also decreases. For the elderly with cardiovascular and cerebrovascular diseases, severe stroke can be induced
