| 摘 要： | 永磁同步电机的转子永磁体励磁磁场中含有的谐波分量,将增加定子绕组内磁链的谐波分量,增大电机的损耗,导致电机温度升高,同时产生转矩波动.根据内置式电机转子磁场的特点,建立电机模型,并在该模型基础上提出一种对磁场谐波抑制的补偿控制算法,通过降低谐波分量来减少定子铁损.同时对电机因磁场谐波引起的转矩波动进行补偿,从而减小振动和噪声.仿真结果表明该补偿控制算法使得磁链谐波分量明显降低,转矩波动减小. |

| Abstract: | Harmonics in permanent magnet excitation magnetic field of permanent magnet synchronous motor(PMSM) may increase the harmonic components in the stator winding flux link and bring more losses in the motor,which will lead to motor temperature rising and torque fluctuation.This paper proposes a compensation of harmonic suppression control algorithm to reduce vibration and noise by reducing the stator iron loss and compensating motor torque fluctuation due to magnetic field harmonics.Simulation results show that with the magnetic flux compensation control algorithm,the harmonic content reduces significantly,the torque ripple decreases,and the motor’s efficiency and performance improve a lot. |
| Keywords: | electric vehicles permanent magnet synchronous motor (PMSM) iron loss harmonic compensation |
