The invention relates to an axial flux motor stator laminated iron core and a manufacturing method thereof, The stator yoke plate is annular, the stator tooth block is an isosceles trapezoidal hexahedron stacked by punching sheets, the connecting screw passes through the stator yoke plate and the connecting key, and the stator tooth block is fixed on one side of the stator yoke plate, and a regular polygon is formed by a plurality of isosceles trapezoidal stator tooth blocks with equal size and longer bottom edges and their extension lines. A manufacture method includes that step of: wrappinga sheet to form a stator yoke disk; The laminated sheet is made into cuboid block tape, and the laminated sheet is bonded with insulating paint with adhesive effect. The rectangular block strip is beveled along the stacking direction of the punched sheet thickness by wire cutting, and decomposed into a plurality of isosceles trapezoidal hexahedral stator tooth blocks with the same size, and the rectangular block strip is divided into a plurality of isosceles trapezoidal hexahedral stator blocks. The stator tooth blocks are evenly distributed and fixed to the stator yoke plate by connecting screws passing through the stator yoke plate. The invention avoids the problems of easy damage of winding insulation and the like, and can ensure the stable operation of the motor.
