"220V AC Cooling Fan" can be divided into the rotor, stator frame, motor (motor) four blocks and other small spare parts assembled. Brushless DC fan configured with several important component are:
1. The fan rotor parts:
    Including fan blades, is a source of generating air flow, fan axis, to support balanced rotating blades, rotor magnetic, permanent magnets, magnetic level switch promote critical speed, magnetic frame, fixed ring
2. "220V AC Cooling Fan" stator section:
   Including support spring, separate balance bearing spindle bearings, providing high-speed, low friction, long life rotates, buckles, fixed tuberculosis entire rotating parts, electrical parts, production and direction of rotation, the rotation speed of the key dynamic size
3. Frame:
    Play a supportive role in the fan motor and diversion;
4. "220V AC Cooling Fan" motor section
Including circuit boards, control energy consumption and signal access, silicon (ie stator magnets, the attached windings) generate magnetic propulsion level switch on silicon, under cover, fixed and insulation;
