| 摘 要： | 异步电机的数学模型通常是忽略铁损的,也是可行的.然而实际上电机的铁损是真实存在的,特别是在效率的分析上,铁损不可忽略.在现有的两种考虑铁损的异步电机模型中,串联铁损模型在磁场定向中不可行,因此本文重点对采用并联铁损模型在磁场定向矢量控制中的应用作深入分析.根据此模型进行数值仿真,仿真与试验结果的比较证明,研究磁场定向时应采用考虑铁损的模型.

| Abstract: | The iron loss is usually ignored in mathematical model of induction motor, and this is also feasible in practice. But the iron loss of motor exists actually, especially in analysis for efficiency. This paper introduces two mathematical models which take iron loss into account. The analysis shows the core-loss resistance in series is not suitable in RFOC, and the numerical results of core-loss resistance in parallel in application to steady state of RFOC are obtained by calculation. Based on d-q coordinate system the mathematical model closed to reality is created for induction motor. Simulation results demonstrate the effectiveness of this method. |
