摘要
本研究采用串励直流电机作为电动操动机构,并给出了该电机的驱动电路,利用电力电子装置控制串励直流电机的转速、运行状态,取代传统的机械换向器,提高系统的效率。结果表明:H桥驱动电路能够实现串励直流电机四象限运行,且能够收集电机制动运行时的能量,提高系统效率。
Series excited DC motor was used as the electric operating mechanism,and the driving circuit of the motor was given,which realized the use of power electronic device to control the speed and running state of series excited DC motor,and replaced the traditional mechanical commutator to improve the efficiency of the system.The simulation results show that the H-bridge drive circuit can realize the fourquadrant operation of the series excited DC motor,collect the energy of the motor during braking operation,and thus improve the system efficiency.
