"Tiny Cooling Fan" the benefits of using a brushless motor. Brushless DC fan is to use to achieve commutation. Due to the presence of carbon brush friction, making the life of the motor brushes and even cut short. Meanwhile, brush at high speeds the process will produce a spark, but also on the surrounding electronic circuits interfere. For this reason, people invented a carbon brush without "Tiny Cooling Fan", also commonly known as a brushless fan. Brushless motor stator windings as, but as a permanent magnet rotor, the structure and brush DC fan opposite. Brushless motor with electronic circuits to switch the order of winding is energized to produce a rotating magnetic field, and promote "Tiny Cooling Fan" rotor rotary motion.
