摘　　要：研究了十二相四Y移15°绕组非对称同步电动机物理结构的动态数学模型,并利用坐标旋转变换将其化简,建立了转子采用多回路模型的dq坐标系动态等效电路及基于MATLAB的可视化仿模型.进行了恒频方波供电情况下的仿真实验,给出了仿真波形,并进行了分析,结果表明仿真波形和电动机运行的实际情况相吻合,证明模型是正确有效的.模型参数简明,使用直观方便,能为对称或非对称十二相同步电机及其各种调速系统的研究和设计提供高效快速的仿真实验手段和科学依据.The dynamic mathematical model for the physical structure of an 12-phase asymmetrical synchronous motor with four Y-connected windings in turn by 15° was studied in the thesis. The model was simplified with coordinate rotation into a MATLAB based visible simulation and a dq coordinate dynamic equivalent circuit, in which multi-circuits are adopted for its rotor. The model underwent simulation tests with a power supply of constant frequency and square wave. The simulation wave form proved to match the actual operation of the motor, which showed the effectiveness of the model. The model characterizes in its simple but handy specifications. It provides an effective simulation solution for research and design of symmetrical or asymmetrical 12-phase synchronous motors as well as other speed-regulation systems.4figs., 8refs.
