摘要
转矩波动包括齿槽转矩和纹波转矩,是永磁电机的固有问题,其平均值为零,不会增加电机的平均转矩,但会导致电机转速产生波动、噪声等影响并对电机的精确控制产生较大影响。
Torque ripple including cogging torque and ripple torque are inherent problems of penrmnent magnet motors Its average value is zero, which will not increase the average torque of the motor, but will cause the motor speed fluctuations, noise and other effects and has a great influence on the precise control of the motor.
