MVI69-S3964R

A、根据负载情况优化电机磁通（严格来说这是降低基波损耗的）；

B、优化变频器的脉冲波形；

C、提高载波频率（具体可参考旧文《变频器载波频率对电机效率的影响》）；

D、配置三电平变频器；

E、使用滤波器（应考虑其引起的电压降）。

附加损耗会使电机温升上升，与工频电源相比，有的可达30K以上。应从改善冷却方式、提高耐热等级、加大电机容量等多种途径考虑其影响。

噪声、振动和扭转振荡

电机转速升高，会使自冷风扇的通风噪声增加。相关数据表明，转速升高20%，噪声增加3dB；转速升高50%，噪声增加10dB。如电机的旋转方向单一，使用轴流风扇对降低噪声非常有效。

电源频率和谐波分量对电磁噪声影响很大。国标GB 10069.3中第7章专门分析了噪声增量，当载波频率较低时，变频器引起的噪声增加量可能高达15dB。电磁噪声的增量与变频器类型、宽频谱设计密切相关。即使电磁噪声的增加并未使电机噪声显著增加，也会显得更加刺耳。
