N2 - Superconducting homopolar motor is the core component of electric aircraft, and its performance directly affects the flight stability, efficiency and energy utilization of aircraft, while the motor torque ripple problem will lead to unstable dynamic response of aircraft during flight, affecting the stability of power system and flight safety. This paper aims at the problem of torque ripple of the superconducting single-pole motor for aviation in the application scenario of high power and high speed. Firstly, the working principle of the superconducting homopolar motor is introduced, and the electromagnetic structure model of the superconducting single-stage motor is established. Then, the generation mechanism of torque ripple of the superconducting homopolar motor under the working condition of high power and high speed is analyzed. Finally, the electromagnetic simulation results show that the proposed method can significantly reduce the torque ripple of superconducting single-pole motor. When the eccentricity is 30mm, the torque fluctuation decreases by 37.78% compared with that before optimization, realizing the most effective suppression of torque ripple and improving the output performance of the motor.
