The flux-switching permanent machine has a larger torque pulsation than other permanent magnet motors due to its unique biconvex pole structure.In this paper,according to the principle of breath magnetic field modulation,the rotor modulation function was adjusted by adjusting the rotor tooth shape to weaken the high-frequency harmonic components and thus reduce the torque pulsation.A reverse arc rotor tooth was pro-posed to suppress the electromagnetic torque pulsation and cogging torque,and thus reduce the output torque pulsation.The reverse arc rotor teeth were designed for a strongly polymagnetic flux-switching permanent ma-chine with a biconvex pole structure to modulate the rotor modulation function.After finite element simula-tion analysis,the reverse arc rotor structure can effectively remove the high harmonics in the air gap,reduce the electromagnetic torque pulsation and cogging torque,make the motor easy to start,and reduce the torque pulsation during motor operation.
