PROBLEM TO BE SOLVED: To provide an axial flux permanent magnet (AFPM) motor with reduced torque ripples, noise and vibrations.SOLUTION: An AFPM motor 100 comprises: a stator including a stator core 110, a magnet wire 120 wound around the stator core 110, a shaft 130, and a stator core supporting member 140 fixedly supporting the stator core 110 to the shaft 130; and a rotor including a rotor case 150 having a space formed therein so as to receive the stator core 110 therein, a magnet 160 fixedly coupled to an inner side portion of the rotor case 150 so as to face the stator core 110, and a bearing 170 rotatably supporting the rotor case 150 to the shaft 130. A ratio between the number of stator slots formed by the stator core 110 and the number of poles of the rotor formed by the magnet 160 is (6×n+9):((6×n+9)+1) or (6×n+9):((6×n+9)-1), where n indicates a positive integer number including 0. |
