Dynamic Models of Induction Machine with Interriegs and Its Performance Analysis

本文采用A、B、C三相坐标系,根据恒功率变换的原则,建立了适合于带中环或不带中环、带一个中环或带二个中环感应电机通用的动态数学模型。利用所得的模型进行稳态性能分析,导出了稳态时的等效电路和电磁转矩表达式,并对测试和计算结果进行了比较。

Dynamic models for three phase squirrel cage rotor induction motor with; one interring or two interrings by using three phase commutator primitives have been developed and presented in this paper. The developed models can be used to predict both steady-state and transient performance. The model are applied to derive the equivalent circuit which reduces to the conventional six parameter circuit for induction motor without interrings. The steady-state performance are also analysed by using the models. The model results are compared with the test resul.
