摘要: 饱和情况下永磁同步电机交直轴之间具有磁耦合特性,传统饱和数学模型需建立3 张交直轴自感和互感二维数表,查表量大。利用Ansys EM 有限元软件分析了某电机饱和特性,提取交直轴电感参数,建立了一种电感参数查表量较少的电机饱和数学模型,并在Matlab 平台进行了仿真实验。结果表明,该模型能准确反映电机饱和电磁特性,且与传统数学模型相比减小了一张二维数表,为永磁同步电机驱动特性研究和控制系统设计提供了一种简化、可靠的模型依据。

Abstract: The coupling effect exists between dq axis of PMSM, it is necessary to establish three sheet of 2D data tables for self-inductance and mutual inductance using traditional saturation digital model, which requires a large amount of table lookup work. A given motor is analyzed using finite element software Ansys EM, the inductance parameters of dq axis are extracted to establish a saturation mathematical model with less inductance parameter lookup work, and is simulated on Matlab platform. Results show that the current model can accurately reflect the saturation electromagnetic characteristics of the motor. Compared with the traditional saturation digital model, the improved model reduces the lookup amount of the 2D induction table, and provides a simplified and reliable model basis for PMSM driving characteristics research and control system design.

Key words: PMSM, cross asymmetric magnetic saturation, finite element, inductance parameter
