Abstract

A micro fan is provided. The micro fan includes a rotor and a stator. The stator includes a plurality of axial induced coil units and a circuit board. The axial induced coil units are respectively preformed as a plurality of stator magnetic pole units, and are coupled to the circuit board. At least one of the coil units includes a coil and insulation material. The insulation material is block-shaped and covers at least a portion of the coil, and the central axis of the coil is parallel to the shaft of the rotor.

Description

technical field [0001] The invention relates to a miniature fan, in particular to a miniature fan which can be manufactured automatically. Background technique [0002] The existing manufacturing method of the fan motor is to wind the winding wires on the pins of the silicon steel sheet to make the stator, and then manually position the stator and weld it on the printed circuit board. However, the existing methods cannot be applied to manufacture micro fans with a thickness below 4mm. [0003] There is another manufacturing method for micro-fans. After winding wires on silicon steel sheets to make a stator, the stator is manually inserted into the bearing sleeve, and then the motor stator is wound and welded on the printed circuit board. Similarly, this method cannot be applied to manufacture micro fans with a thickness lower than 4mm. In addition, the existing manufacturing methods may also cause poor welding operations or structural interference due to human errors. Co...
