DC [micro] role of the various components of the fan

　　DC micro fans have two main parts, the rotor and stator, broken down as follows:

　　1, the fan frame: support from the fan motor and fan waterproof diversion effect

　　2, 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

　　3, the fan motor parts: 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;Cooling fan

　　4, fan stator section: Includes 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, rotation speed dynamic size key
