Abstract: A stator structure for a direct-current fan motor includes a stator seat, a spindle position thereof being provided with a permeability tube. An even number of winding regions is distributed uniformly around the outer periphery of the permeability tube. The winding regions receive coil windings and each has a hollow interior for receiving a magnetic pole inserted thereinto. One side of the spindle of the stator seat is provided with substrate barbs and frame barbs that secure a circuit board and position the stator structure on a frame.

Abstract: An improved stator structure for industrial cooling fans includes silicon steel plates punched directly into shape to allow direct magnetic conductance so as to enhance field intensity. Upper and lower silicon steel plates are passed through plastic insulating packing pieces and inserted into recessed grooves of a plastic sleeve. The assembly is then riveted in tight fit to achieve a motor stator structure.
