Micro Cooling Fan voltage and electromagnetic induction

"Micro Cooling Fan" is a DC voltage and electromagnetic induction, the electrical energy into mechanical rotation so as to drive the blades. DC fan wheel and blade design, with the wind and air pressure and DC fan blades collide compression capability is closely related to a serious point that affects the grade and quality of the entire DC fan, how to design efficient and simple process of "Micro Cooling Fan" The main problem has been the researchers studied, the design efficiency impeller blades is the main way to solve this problem. Balance between the DC cooling fan blade to the performance of the DC fan, DC fan blade balance of more positive commonly used dynamic balance, it is the principle of the stationary blade adjustable "Micro Cooling Fan" and the single-stage variable pitch fan DC because it is only one level of the impeller, mass imbalance caused due to wear it all focused on the impeller, the balancing process is a single plane balancing process, namely static equilibrium process.
