摘要
从电机状态方程出发,详细地分析了无刷直流电机的PSpice模型。利用PSpice电压控制电压源生成逆变器功率管换流信号,建立了适合PSpice的无刷直流电机系统的等效电路仿真模型,进而对电机的控制系统驱动电路进行了仿真。仿真结果与理论分析一致,证明仿真可以帮助我们设计和调试无刷直流电机的控制系统。
Based on motor state equation,this paper analyzed the model of a brushless DC motor（BLDCMTR）.Firstly,it set up an equivalent circuit model of BLDCMTR by using PSpice to control voltage source to produce the voltage signal.Then the simulation of BLDCMTR s control system was carried out.The simulation results are similar to the theoretical analysis.All this shows that the whole system simulation will be helpful for designing and testing the drivers of BLDCMTRs.
