An axially central part of the motor flux. The utility model technical solution is as follows: A core assembly axial flux motor comprising two parallel core and core clamp, the clamp is circular core, the core of said jig in two parallel cores, along the core circumferentially uniformly distributed and fixed clamping of the core in the core holder, wherein: said core is trapezoidal cross-sectional shape in the axial direction, adjacent mandrel and the distance between the cores adjacent to each other is equal to parallel to an edge. The utility model has the advantages: Allows a coil wound around the core without increasing the cross-sectional area larger or more lines, more torque, to change its shape under the conditions, increasing the motor coil of the induction motor drive a larger cross-sectional area of the coil winding force, the internal resistance of the motor is reduced, the motor becomes more efficient
