The main flux of asynchronous motor varies with the power voltage and the para-meter of excited inductance becomes a variable.
电源电压变化时，异步电动机主磁通随之变化，与之相应的激磁电感参数将是一个变数。
It is suitable to be used as precise inductance standard for all kinds of metrology units, research institutes, and manufacturers, and especially suitable for on-site LCR meter calibration.
适用于各计量、科研与生产部门作精密电感标准，尤其适用于对LCR表进行现场校准。
