  • a conveyor device that is operable to move material via a flexible member along a single conveyor that is propelled by two or more motors in a load sharing drive control application;

    a computer for processing data;

    a dynamic mathematic model calculation program executed by said computer, said program being operable to continuously evaluate the torque requirements of the system and produce a signal responsive of actual torque demands;

    a PLC operable to monitor and control all input and output devices associated with the conveyor;

    a motor controller in communication with the PLC, said controller is operable to receive input data from the PLC and deliver torque and speed power outputs to a motor;

    a motor operable to receive the torque and speed power outputs and provide power to a primary moving element of said system; and
