| Abstract: | Based on the study and comparison made to the structure and closing time of power breakoff time delay relays and contactors,the paper analyses the inadequacies of the original energy exhausting braking control circuit,and some improvements have been made.Only one pair of auxiliary headers of contactor is added to the improved control circuit,but the performance of motor is improved and the service life of contactors is prolonged as well. |
