  • Large Grinding Mills Dual-Motor Drives

    The dual motor drive concept utilizes two (or more) motors, either synchronous or induction type, coupled through HVD's and reduction gearing to two (or more) pinions driving the mill either via a conventional girth gear, shaft-mounted bullgear, or direct coupled gear. In any case, electrical load sharing is inherent in the concept.

    Since the motors drive through pinions engaging the drive gear 10 on opposite sides, these pulsations are approximately l apart in the two motors and occur at a frequency equal to the speed of the mill 1, so that in effect an unbalanced load oscillates back and forth between the two motors at a frequency corresponding to the mill speed. This large oscillation of load between the two motors is ...
