摘　　要：在详细分析六相四对极双Y移30°永磁同步电机的理论基础上,引入绕组函数和倒气隙函数概念对其电感参数进行定量分析,建立完整的数学模型并对模型进行仿真。首先,在自然坐标系下建立基于绕组函数和倒气隙函数的电机数学模型;然后,根据坐标变换理论得到二相旋转坐标系下的电机数学模型;最后,按照上述推导的数学模型在Matlab/Simulink中建模和仿真。仿真中采用基于有效作用时间的PWM控制策略来控制电机运行,得到良好的控制性能。A complete mathematical model was established and simulated on the basis of detailed analysis of six-phase four pair poles dual Y shift 30° PMSM. Firstly, a motor mathematical model based on the winding function and air gap reciprocal function was built in the natural coordinates. Then the motor mathematical model in the 2 phase rotating coordinate system was obtained with the coordinate transformation theory. Last- ly, a model was built in Matlab/Simulink according to the mathematical model stated above and simulations are conducted. The effective imposing time based control strategy was used to control the motor in the simu- lation which led to good performance of the motor.
