【摘要】 针对双模式逆变拓朴结构可达到较好弱磁扩速效果的目的,对一种新型逆变器结构的无刷直流电机弱磁扩速系统进行了仿真。仿真结果表明,在保持逆变器容量不变的情况下,基于新型逆变器的无刷直流电机系统具有更宽广的扩速范围,并且还具有结构简单的特点,应用前景广阔。更多还原

【Abstract】 This paper presents a new control method of BLDCM in order to get a wide speed range.The simulation models of the two control systems are built with MATLAB/SIMULINK.From the simulation result,it’s easy to find this new method can get a better CPSR than traditional method without any changing of the motor rotor.更多还原
