采用有限元方法在考虑笼型异步电动机的端部漏抗、端部电阻、铁心饱和特性以及转子导条集肤效应的情况下准确计算了三相笼型异步电动的起动电流。试验证明,所计算起动电流值与实测值相差5%以内。
採用有限元方法在攷慮籠型異步電動機的耑部漏抗、耑部電阻、鐵心飽和特性以及轉子導條集膚效應的情況下準確計算瞭三相籠型異步電動的起動電流。試驗證明,所計算起動電流值與實測值相差5%以內。

The finite element method was used to calculate the starting current in three-phase induction motor by considering end leakage, end reactance of squirrel cage, saturation characteristics of core and skin effect in the bar. The error of the calculation was proved to be within 5% compared with the test result.
