摘要

To provide a conveyance drive device capable of suppressing current consumption of a motor during a steady state when driving the same drive shaft at a different torque with two motors.SOLUTION: There are provided a first motor for transmitting power to a drive shaft of a roller; a second motor for transmitting the power to the drive shaft, together with the first motor, at a torque smaller than that of the first motor; and a control part for setting each of setting values of driving currents of the first motor and the second motor in a steady state of the roller rotating in a constant set speed in such a manner that a total value of the current consumption of the first motor and the second motor becomes minimum.SELECTED DRAWING: Figure 5
