Research on Drive Topology and Control Strategy of Series Excited DC Motor Operating Mechanism
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 four-quadrant operation of the series excited DC motor,collect the energy of the motor during braking operation,and thus improve the system efficiency.
