"DC Cooling Fan" features a strong machine control structure is also more complicated. Due to technical content increasing cooling fan motor, if not quite understand its details, it is difficult to properly install and use. Therefore, this article focuses on the motor cooling fan used to analyze. The basic working principle of DC power supply based on different ways, "DC Cooling Fan" has a DC motor and AC motor types. Computer cooling fan motors used for DC motor, power supply voltage of + 12V, speed of between 1000 to 10,000 rev / min. DC is the DC energy is converted to mechanical energy of rotating machinery. "DC Cooling Fan" by the stat, a rotor and a commutator of three parts, a stat (i.e., the main magnetic pole) is fixed on the fan bracket, the non-rotating part of the motor.
