Canned induction motors fed by inverters are widely used in pharmaceutical, chemical, and nuclear fields. It is necessary to analyse the effect of time harmonic injected by the inverter on the performance of the canned induction motor. However, the existing researches are to consider the inverter and the motor separately, without analyzing the reverse effect of the induction motor as a nonlinear active load on the time harmonics of the inverter. Therefore, this paper establishes a field-circuit coupling analysis model of the canned induction motor considering the influence of load, and studies the effect of time harmonic current under different load conditions on the electromagnetic field, eddy current loss, and temperature field of the canned induction motor. The paper first uses the analysis method to determine the relationship between the time harmonic voltage of the inverter and the time harmonic current of the motor. Then, the electromagnetic field distribution, eddy current loss, and temperature field distribution of the canned induction motor under different load conditions are calculated. Besides, the laws of time harmonic current on the electromagnetic field, can loss and motor temperature distribution are found. These research results can not only provide a meaningful reference for analysis of the canned induction motor but also provide methods for design optimization and multi-physical field modeling analysis of the canned induction motor.

考虑负载条件的时间谐波电流对屏蔽电机性能的影响

由逆变器供电的罐装感应电动机广泛用于制药,化学和核领域。有必要分析逆变器注入的时间谐波对固定式感应电动机性能的影响。然而,现有的研究是将逆变器和电动机分开考虑,而没有将感应电动机作为非线性有功负载对逆变器的时间谐波的反向影响进行分析。因此,本文考虑负载的影响,建立了屏蔽感应电动机的场-电路耦合分析模型,研究了不同负载条件下的时间谐波电流对屏蔽电磁场,涡流损耗和温度场的影响。感应电动机。本文首先使用分析方法来确定逆变器的时间谐波电压与电动机的时间谐波电流之间的关系。然后,计算了在不同负载条件下的屏蔽式感应电动机的电磁场分布,涡流损耗和温度场分布。此外,还发现了时间谐波电流在电磁场,罐损耗和电动机温度分布上的规律。这些研究结果不仅可以为罐装感应电动机的分析提供有意义的参考,而且可以为罐装感应电动机的设计优化和多物理场建模分析提供方法。计算了不同负载条件下的屏蔽式感应电动机的温度场分布。此外,还发现了时间谐波电流在电磁场,罐损耗和电动机温度分布上的规律。这些研究结果不仅可以为罐装感应电动机的分析提供有意义的参考,而且可以为罐装感应电动机的设计优化和多物理场建模分析提供方法。并计算了不同负载条件下的屏蔽式电动机的温度场分布。此外,还发现了时间谐波电流在电磁场,罐损耗和电动机温度分布上的规律。这些研究结果不仅可以为罐装感应电动机的分析提供有意义的参考,而且可以为罐装感应电动机的设计优化和多物理场建模分析提供方法。
