[Abstract]:According to the requirements of the preliminary design and verification of the motor, the electromagnetic performance analysis method based on the dynamic magnetic network combines the advantages of the traditional equivalent magnetic circuit method and the finite element method. The application of many empirical formulas and hypotheses in the equivalent magnetic circuit method is avoided, and the calculation accuracy is improved effectively, and the number of mesh generation is reduced compared with the finite element analysis method, and the equivalent flux tube is used as the basic element. The time required for calculation is shortened and computing resources are saved. In this paper, a 600kW permanent magnet synchronous motor (PMSM) is studied. Based on the principle of dynamic magnetic network, the dynamic magnetic network model of PMSM is established, and the geometric solution method of non-uniform air-gap equivalent magnetic conductance is analyzed. The simulation software of permanent magnet synchronous motor (PMSM) dynamic magnetic network is designed and developed in MATLAB programming environment. By using this analysis software, the no-load characteristics of PMSM are simulated, and the effect of rotor segment inclined pole on weakening stator tooth harmonics is compared and compared with the finite element analysis results. The efficiency and accuracy of the dynamic magnetic network analysis software are verified. Based on the method of frozen permeability, the variation of induction inductance of PMSM with the saturation of PMSM is studied by using the software. The influence of armature current variation on inductance under different operating conditions is analyzed. On the basis of dynamic parameters, the steady operation characteristics of motor load are analyzed. Based on the dynamic magnetic network analysis software, the interface between the software and the Simulink control system model of PMSM is designed, and the id=0 vector control method and the maximum torque / current-current ratio vector control method are used to carry out the joint simulation, respectively. The advantages of maximum torque to current ratio control in salient synchronous motor control are discussed, and the results of dynamic parameter model and constant parameter model are compared and analyzed.
