A new stator fixing method for axial flux motor without iron core

The coreless axial flux motor has the advantages of small torque ripple and high power density. It has wide application value in the fields of high torque, high overload, limited installation size and so on. The axial flux motor with double rotor and single stator is widely used at present, and its power density is higher than that of other axial motors with topology structure, so it has high research and application value. The fixing of stator coil is a difficult problem of single-stator dual-rotor axial flux motor without iron core. The traditional methods have the disadvantages of using epoxy resin to bond the stator winding to the shell or using support plate to support the winding, which occupy the axial air gap of the motor and are easy to produce vibration. This paper presents a new stator fixed structure, which has the advantages of no air gap, high strength and low fabrication difficulty.
