本文估计电机寿命时，电机提供了一个组合的过电压或欠电压与不平衡的电压。通过使用阿克里尼乌斯方程估算鼠笼式电动机定子绕组绝缘寿命来预测电动机寿命。电气和热模型分别用于计算电机损耗和温度。热模型参数是从简单的电机测试技术而不是从复杂的方法，需要电机设计数据
This paper estimates motor life when a motor is supplied with a combination of over- or undervoltages with unbalanced voltages. The motor life is predicted by estimating the stator winding insulation life of squirrel cage motors using Arrhenius' equations. Electrical and thermal models are used to calculate motor losses and temperatures, respectively. The thermal model parameters are obtained from simple motor testing techniques rather than from complex methods requiring motor design data
