Q: How to pick an electric fan?: Consider the number of fans, the same fan, if the other parts remain unchanged, only the leaves from five fan leaves to seven fans, the air volume changes may not increase much

Q: Where does the wind from the electric fan come from?: The Bernoulli principle. Just like an airplane has wings,

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: Why not head fan to blow?: Blow to the head when the heart and brain stroke

Q: What is the principle of a vaneless fan?: The base will be a large amount of air from the suction hole at the bottom of the 5.28 gallons per second flow inhalation, then the air is pressurized into the annular inner wall, an impeller inside the edge of the ring in the air circular trajectory jet, change the air flow will cause the air pressure, and ultimately the formation of a cold air flow shares uninterrupted

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: 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: Fans can shake their heads, but fan leaves do not turn, where is the reason?: The motor is short of oil, jammed or covered with hair

Q: What are the new electric fans?: Time control electric fan: just set the time of the fan work, it will be set according to your, on time, off on time.

Q: What are the types of electric fans?: According to the structure of the motor can be divided into: a single-phase capacitor type single-phase, three-phase, shaded pole induction, DC and AC / DC series excitation commutator type electric fan.
