摘　　要：提出了一种双三相异步电动机的建模新方法。基于磁动势和功率不变的原则,构建了一套等效的三相绕组。应用成熟的三相异步电动机在两相静止坐标系上的数学模型,建立了双三相异步电动机在α-β坐标系上的数学模型和基于Simulink的仿真模型。设计制作了一台4极、1.1kW的双三相异步电动机并进行了仿真和试验对比研究。结果表明,仿真结果与试验结果吻合,两者间的最大误差在2%以下。这种基于绕组变换的建模方法是正确有效的。A novel mathematic model for a dual three-phase asynchronous electrical machine was proposed. A set of equivalent three-phase windings was built based on same magnetomotive force and power. A dual three-phase asynchronous electrical machine was substituted equivalently by a three-phase asynchronous electrical machine after a winding transformation. Then with the mathematical model of the three-phase asynchronous electrical machine in the stationary reference frame, the model of a dual threephase asynchronous electrical machine was determined. A 4 electrical machine was simulated and tested. Compared the suits, the maximum error is lower than 2%. So this dated to be correct. winding pole 1.1 kW dual three-phase asynchronous simulation results with corresponding test retransformation and modeling method are validated to be correct.
