Abstract

PURPOSE:To control the speed of motors with simple structure at low cost by arbitrarily controlling the drive of two targets to be driven with single AC power source. CONSTITUTION:Since the secondary coils 12A, 12B of a stepdown transformer 11 are so wound as to generate the same phase voltages in the direction as designated by solid circles, the voltages at the points A, B produced by rectifying in different directions with diodes 13A, 13B are divided into half positive and negative cycle voltages at every half cycle of the AC commercial power frequency supplied to the primary coil of the transformer 11 at the common point C. During the period of half positive cycle, a current IA flows to rotate a DC motor 18A and to move a locomotive 2A. During the perod of half negative cycle, a current IB flows to drive a DC motor 18B and to move and control a locomotive 2B.
