<p>PURPOSE:To perform the readhesive control of an electric motor vehicle by simultaneously controlling and operating the total number of choppers in accordance with the maximum value of a current which flows through the armatures of a plurality of DC motors to be controlled by the different choppers. CONSTITUTION:The armature circuits of a plurality of DC motors 5, 9, 13, 17 are respectively controlled by choppers 7, 11, 15, 19. A high order priority circuit 26 selects the maximum of the currents of the motors 5, 9, 13, 17 and outputs the current to the control circuits of the respective choppers 7, 11, 15, 19. The control circuits respectively controls the choppers 7, 11, 15, 19 so that the output of the priority circuit 26 becomes equal to the limited current value. In this manner, an optimum readhesive control can be performed even without particular idle readhesive control.</p> |
