考虑饱和及转子磁场谐波的永磁同步电机模型
Model of Permanent Magnet Synchronous Motor Considering Saturation and Rotor Flux Harmonics
摘要
Abstract
The inductance and the flux linkage excited by the permanent magnet (PM) are largely influenced by the saturation of permanent magnet synchronous motor (PMSM),and the air gap flux excited by the PM often contains large amount of space harmonics. However, the traditional linear mathematic model of PMSM cannot reflect the effects of these factors as mentioned above on the operation performance of motor. In this paper, a general finite element method (FEM) based d-q axis variable modeling method of PMSM was proposed. A general nonlinear d-q axis variable mathematic model of PMSM was established taking account of the effects of saturation and space harmonics, in which the d-q axis inductance and the flux linkage excited by PM were obtained from the finite element solutions by using Ansoft. A new M function based simulation model was implemented in Simulink using the equation of the established nonlinear model. The simulation and experimental results of a PMSM show that the proposed nonlinear model is correct and has perfect precision,which provides a fast, accurate and efficient modeling method for the characteristic and the drive system dynamic precise analysis of PMSM.关键词
