Tiny Cooling Fan principle and speed

Principle: "Tiny Cooling Fan" works by energy conversion to achieve, namely: energy electromagnetic energy → → → kinetic energy to mechanical energy. The circuit principle is generally divided into a variety of forms, using different circuits, there will be differences in the performance of the fan. Axial "dota雷竞技 " consists of: fan box, blades, bearings, PCB control circuit drive motor. 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, "dota雷竞技 " leaf shape and the bearings and other factors, the speed increases, the air flow is increased accordingly.
