228. Study on Multi-Motor Power Balance of Controlled Speeder for Belt Conveyor

In this paper, the dynamic and static influencing factors of multi-motor power balance for belt convey was discussed and thus the corresponding engineering solution was put forward through analyzing the power balance course of active control for belt conveyor. The new solution which collects the current and speed signal simultaneity as the control bases to solve the power balance for belt conveyor was put forward and the correctness and feasibility of the principle was discussed and then the hardware and software design of electric control system were introduced in detail. The experiment test showed that the electric control system was able to accurately control mechanical drive and hydraulic devices and realize the functions of soft start and soft stop and the belt conveyor had characteristics such as steady power, quick response-time, extensive tape speed range and high transmission efficiency.
