摘要
Abstract
To meet the design requirements of electric vertical take-off and landing(eVTOL)aircraft for low torque ripple and high reliability of drive motors,an interior permanent magnet synchronous motor(IPMSM)is designed.To enhance torque characteristics,the Taguchi method is employed to design the experimental matrix,and a response surface surrogate model for cogging torque is constructed to perform multi-objective optimization of the stator and rotor lamination parameters.V-shaped rotor step skewing is adopted to suppress harmonics and optimize torque ripple.Finite element simulation results show that the peak-to-peak cogging torque is reduced from 3.038 N·m to 0.084 N·m,torque ripple is reduced from 12.2%to 7.5%,and the total harmonic distortion(THD)of back electromotive force is reduced from 4.07%to 2.12%.This study provides a reference for the engineering design and performance optimization of eVTOL drive motors.关键词
