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.
