Law 220V AC Cooling Fan operation

"220V AC Cooling Fan" factory everyone, whether things have to do with any of its laws and principles, and the principles of operation of the DC fan is based on right-hand rule ampere, the conductor through current creates a magnetic field around, if this conductor placed in another fixed magnetic field, will produce suction or repulsion, causing objects to move. Let us work together to understand the knowledge of DC fans: air volume refers to "220V AC Cooling Fan" ventilated area and the volume of the area of the flat rate. Ventilation area is subtracted from the outlet area of the projected area at the vortex of the tongue. Plane speed velocity gas flow through the entire plane, in meters / sec. Flat rate constant, "220V AC Cooling Fan" blade impeller diameter, the greater the ventilation area, the greater the amount of wind.
