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:What is the principle of an automatic fan head swing back and forth?: The other end of the pendulum button is a gear, and when it goes down, it coincides with the gear that rotates under the fan, so the gear below will push the fan to swing

Q:How do you use an electric fan to set up an air distribution system in an air tight room?: In contrast, outdoor, room because of the enclosure, radiation and heat inside the reasons, in most cases, the temperature will be higher than the outdoor level. In the temperature stratification under the condition of the same, because the overall warmer indoor air temperature smaller, resulting in a lesser level of indoor air pressure difference outside the same distance.

Q:What are the new electric fans?: No noise fan: Japanese Mitsubishi Co to develop the electric fan almost no noise, a bird's wing shaped blade special, can produce a vortex flow, and the use of DC motor, with protective cover, very suitable for use with microcomputer, word processor, copier place.

Q:How was the electric fan invented?: In 1880, Americans for the first time Shule blade is directly mounted on the motor, and then connected to the power supply, the rapid rotation of blades, the cool breeze blowing, this is the world's first electric fan.

Q:How to pick an electric fan?: The fan leaves of a bamboo, streamlined appearance.

Q:How to measure the quality of fan motors with digital multimeter?: The DC resistance between the 3 wires is measured respectively by the multimeter. The maximum value is the resistance value of the starting winding and the running winding, followed by the resistance value of the starting winding and the resistance value of the running winding.

Q:What is the difference between air conditioner speed regulation and electric fan speed regulation?: Inverter air conditioners and fans are asynchronous motors (not sure if there are any other types, but common ones). The fan is single-phase and the air conditioner is multiphase.

Q:Why does the electric fan always rotate clockwise?: It may be related to power. The steering of the motor is subject to alternating current, and the alternating current is standard, so that should be the reason.

Q:Where does the wind from the electric fan come from?: At the same time, the air velocity of the diagonal line must be faster than that of the straight line, causing the air pressure on both sides to vary. The air flowing along the straight line flows to the side of the air where the wind is formed
