摘　　要：提出了一种双三相永磁同步电动机的数学建模新方法.基于产生相同磁动势和功率不变的原则,构建了一个等效的三相绕组,绕组变换后,原双三相永磁同步电动机等效为普通的三相永磁同步电动机.应用三相永磁同步电动机在两相同步旋转坐标系下的数学模型,完成了双三相永磁同步电动机在d-q坐标系下的数学建模和基于Matlab/Simulink的仿真建模.对一台6极双三相永磁同步电动机进行了仿真和实验,两者间最大误差在5%以内,因此该建模方法是有效和正确的.A novel mathematical model for a dual three-phase permanent magnet synchronous machine（PMSM） was proposed. A set of equivalent three-phase windings was established based on the same magnetomotive force and power. A dual three-phase PMSM was substituted equivalently by a three--phase PMSM after a winding transformation. Then following the mathematical model of the three-phase PMSM in the rotary reference frame, the model of a dual three-phase PMSM was determined. A f-pole dual three-phase PMSM was simulated and tested. Compared the simulation results with the corresponding test results, the maximum error got lower than 5% to demonstrate the validity and effectiveness.
