The invention discloses a fabrication method of an amorphous and nanocrystalline stator iron core for an axial magnetic field motor. The method comprises steps of annular element winding, curing processing, groove cutting and annealing, in the step of annular element winding, an alloy strip is wound to form an annular element with predetermined inner diameter and external diameter, and during the winding process, a layer of bonding agent is synchronously dip-coated on the surface of the alloy strip before winding so that the amorphous or nanocrystalline strips of adjacent layers after winding can be bonded together to form the annular element. The amorphous and nanocrystalline stator iron core disclosed by the invention has a high lamination coefficient and low iron core loss, the loss of the amorphous and nanocrystalline stator iron core can be reduced than that of a silicon steel core by over 80%, and the amorphous and nanocrystalline stator iron core is suitably used in a high-frequency motor with frequency of over 400Hz. Moreover, the amorphous iron core obtained according to the method is excellent in soft magnetic property, high in production efficiency, low in manufacturing cost and high in finished rate, and is suitably used for opening a groove with relatively wide width.
