In view of the energy waste generated by driving the main engine to reverse brake when the escalator is in descending condition,an energy-saving escalator driving system scheme based on direct drive volume control scheme was proposed,the simulation model of the system and the driving control system of the escalator were built by using AMESim.Through the simulation analysis, it is proved that this scheme can recover the gravity potential energy of the load when the escalator goes down, and it also verifies that the system is energy-saving.This scheme provides a idea for the design of new energy-saving escalators.
