Abstract: Axial flux switched reluctance motors have the advantages of traditional switched reluctance motors and axial flux motors, and can be applied to many occasions. Taking into account the problem of fixing the rotor magnetic poles during the assembly process of the engineering prototype, a boss structure was introduced into the rotor. The influence of the stator and rotor pole arc coefficients and rotor thickness on the motor performance of the axial flux switched reluctance motor under ideal conditions was studied.Under the premise of keeping the stator and rotor pole arc coefficients and rotor thickness unchanged, the introduced boss structure were analyzed, and the best boss thickness and boss width were selected. The finite element analysis(FEA) was used to compare the axial flux switched reluctance motor with a bossless rotor structure and a boss rotor structure. The research results show that the rotor structure with bosses can effectively improve the output torque of the motor and enhance the reliability of the rotor structure.
