It states the application and the theory of the energyconsumptionbrake in the Rotary Table control system, analyses the course of motor start and brake.
In addition to this great accomplishment, the subway cars themselves were made more efficient by introducing a new brakeenergy recovery system that reduces energy consumption by 33 percent.
The ways of cancelling over voltage are setting up deceleration time, consumption of energy, feedback electric network brake and Shared direct current bus bar soaking regenerated energy.
