| 摘 要： | 由于变频电源的输出含有大量的高次谐波,这些谐波会产生相应的铜耗和铁耗,使电机固定损耗增加,电机温升增高,降低运行效率和功率因数,因此变频电源供电下电动机的谐波损耗是一个大问题。

| Abstract: | As the output of variable-frequency power supply contains a lot of high-order harmonics,these harmonics will produce the corresponding copper loss and iron loss,and they can reduce operation efficiency and power factor.The harmonic loss of motor fed by variable-frequency power supply,therefore,is a big trouble. |
