提出了感应电机 (IM) 的快速半解析模型。与传统的IM分析模型（例如集总参数、磁等效电路和各向异性层模型）相比，该模型计算了IM的气隙以及定子和转子槽中磁通密度的连续分布。由于其半分析性质，与有限元分析 (FEA) 模拟相比，模型的计算时间较短。然而，典型 IM 槽的弯曲形状需要在极坐标中对每个槽进行适当的表示。研究了两种不同的极性槽表示，结果表明双区域表示优于单区域表示。最后，该模型针对四种不同的基准电机进行了实施。计算结果与线性二维有限元模拟结果非常吻合。这使得该模型成为快速设计工具的合适候选者。
A fast, semi-analytical model for induction motors (IMs) is presented. In comparison to traditional analytical models for IMs, such as lumped parameter, magnetic equivalent circuit and anisotropic layer models, the presented model calculates a continuous distribution of the magnetic flux density in the air gap and both the stator and rotor slots of the IM. Due to its semi-analytical nature, the computation time of the model is short in comparison to finite element analysis (FEA) simulations. However, the curved shapes of typical IM slots require a suitable representation of each slot in polar coordinates. Two different polar slot representations are investigated and it is shown that a double region representation is favorable to a single region representation. Finally, the model is implemented for four different benchmark motors. The calculation results are shown to be in good agreement with linear 2D FEA simulation results. This makes the model a suitable candidate for fast design tools.
