摘　　要：在研究内置式永磁同步电动机交直轴磁链和电感非线性特性的基础上,对电动机参数进行了实测研究,给出了d-q轴磁链和电感拟合的表达式。建立了d-q轴系下内置式永磁同步电动机精确的数学模型,依据该模型对内置式永磁同步电动机进行了仿真研究。仿真结果与实验结果的比较证明了所建立的非线性模型能够准确地反映电动机的实际运行状况。该模型有助于对内置式永磁同步电动机系统进行深入研究。Based on the nonlinear characteristic analysis and the measurement of d and q axis fluxes and inductances for interior permanent magnet synchronous motor （IPMSM）, the fitting expressions of the d and q axis fluxes and inductances were given,and then a nonlinear model of the IPMSM was established and realized. Simulation analysis was compared with experimental results. The results validated the model was reasonable and reflected actual running performance, which contributed to the deep study of the IPMSM.
