GB/T 20161-2006 in English

《GB/T 20161-2006变频器供电的笼型感应电动机应用导则》由TC26（全国旋转电机标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准研究适用于JB/T 8158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。

Scope

This standard research applies to the steady-state operation of cage induction motors within the scope of JB/T 8158 standard within the speed setting range when powered by a frequency converter, excluding starting or transient phenomena. This standard only involves indirect frequency converters. This type of frequency converter includes frequency converters with external direct current (current type frequency converter) and external DC voltage (voltage type frequency converters) with intermediate circuits, or square wave type or pulse control type, without limitation Number of pulses, width or pulse frequency. The frequency converter involved in this standard can be an analog control circuit or a digital control circuit. The electronic switching device of the frequency converter can be of any type, such as transistor (bipolar or metal oxide field effect tube MOSfet), insulated gate Bipolar transistors (IGBTs), thyristors, turn-off thyristors (GTOs), etc.
