摘　　要：为了研究船舶电力推进系统,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,先将双三相绕组等效变换为双两相绕组,再将双两相绕组等效变换为两相绕组.经过2次绕组变换后,双三相绕组等效变换为两相正交绕组.应用成熟的两相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dq坐标系下的数学建模和基于Matlab/Simulink的仿真建模.设计了一台6极、2.2 kW的双三相永磁同步电动机,进行了仿真和试验研究.比较仿真结果和试验数据,两者间最大误差在5%以内,该建模方法是有效和正确的.A novel mathematic model of a dual three-phase permanent magnet synchronous motor （PMSM） was proposed to study electrical propulsion systems for ships. First the dual three-phase windings were transformed to equivalent dual two-phase windings with the same magnetomotive force and power, and then the dual two-phase windings were transformed to equivalent two-phase windings. After the above transformations, dual three-phase windings were equivalently transformed to two-phase orthogonal windings. With the mature mathematical model of the electrical machine in the two-phase rotary reference frame, the model of a dual three-phase PMSM was established. A mathematical model of 6-pole, 2.2 kW dual three-phase PMSM in the dq coordinate system was built and simulated by Matlab/Simulink. Comparing the simulation results with corresponding test results, the maximum error was less than 5%. So this double winding transformation and modeling method is valid and correct.
