PURPOSE:To prevent a car body from being twisted, by driving left and right driving motors in the same speed, when an unattended carrying car of electromagnetic induction type runs in the direction orthogonal to the lengthwise direction. CONSTITUTION:Left and right driving devices A, B are provided with speed feedback tachogenerators TA, TB and chopper controllers CA, CB respectively and two driving motors 2, 5 are independently controlled with the output from a microprocessor DO. Thus, the driving motors 2, 5 are rotated with the same speed to correct the oblique motion and twisting of the car body. |
