摘　　要：为简化无刷直流电机控制系统设计,提出了一种基于Maxwell、Simplorer、Simulink的无刷直流电机调速系统建模与联合仿真的方法。以常用的三相星形结构无刷直流电机为例,首先利用基于磁路法的电机建模软件RMxprt对电机本体进行初始设计与性能校核,然后利用Maxwell进行瞬态和稳态运行分析的有限元计算,基于Simplorer搭建系统功率逆变电路,最后在Simulink中编写电机换向逻辑单元,进而对组成的机电一体化系统进行联合仿真。通过仿真实验,验证了文中模型及方法的有效性,且该联合仿真更接近实际电机运行的工况。实验结果表明,该联合仿真方法能够为以后研究和设计无刷直流电机控制系统提供一种有效的途径,具有很高的实用价值。Proposed a co-simulation method based on Maxwell, Simplorer, Simulink for brushless DC motor speed control sys- tem modeling in this paper.
