"Tiny Cooling Fan" principle: Fan works by converting energy to achieve, namely: energy electromagnetic energy → → → kinetic energy to mechanical energy. The circuit principle is generally divided into many forms, using different circuits, there are differences "Tiny Cooling Fan" performance will be.
The axial fan: the fan frame, blades, bearings, PCB control circuit, the drive motor
"Tiny Cooling Fan" Speed: speed refers to the speed of rotation of the fan, usually within one minute laps to measure the rotation, namely: rpm. Electromechanical speed winding turns, diameter, blade impeller diameter and bottom diameter, leaf shape and the bearings and other factors, the speed increases, the air flow is increased accordingly.
