引言

变频器供电笼型感应电动机驱动系统的工作特性和运行性能受到整体驱动系统的制约，包括供电

系统、变频器、感应电动机、机械轴系以及控制装置，其中每一部分的技术类型繁多，本标准引用的一些

量值仅为提示性质。

驱动系统的设计涉及到一些重要参量，考虑到系统内复杂的技术关联和运行状态的多样性，要对这

些参量规定数值或限值已超出了本标准的范围和目的。

现实情况是大多数驱动系统是由不同制造厂生产的部件组成的。本标准的目的在于对选用部件的

准则以及部件对驱动系统运行性能的影响作出说明并尽可能地定量表示。

变频器供电的笼型感应电动机应用导则

范围

本标准研究适用于JB/T8158标准范围内的笼型感应电动机由变频器供电时在速度设定范围内的

稳态运行，不包括起动或瞬态现象。

本标准仅涉及间接型变频器。此类变频器包括带中间回路的外施直流电流的变频器(电流型变频

器)和外施直流电压的变频器(电压型变频器)，或为方波型或为脉冲控制型，没有限制脉冲的数量、宽度

或脉冲频率。本标准所涉及的变频器可为模拟控制电路，也可为数字控制电路，变频器的电子开关器件

可以是任何类型的，如晶体管(双极的或金属氧化物场效应管MOSfet)、绝缘栅双极晶体管((IGBTs)、晶

闸管、可关断晶闸管(GTO)等。

电动机的特性

在换流期间，电流型变频器的输出电流要流过电动机的定子绕组。因此，电动机的等值电路知识对

换流电路的设计是重要的。

对电压型变频器，电动机的等值电路知识对换流电路的设计通常并不重要，但是电动机的谐波阻抗

对因谐波引起的损耗却有重大的影响。

上述情况关系到驱动的基本运行能力。如果要求知道变频器供电运行时出现的附加转矩(特别是

振荡转矩)和附加损耗的具体细节，则需要知道电动机在整个谐波频谱范围内的等值电路参数。
