PURPOSE:To obtain a simple configuration by providing rectifiers common between the 1st and 2nd motor. CONSTITUTION:Rectifiers 11-14, 17, 18 are connected to the secondary windings 3-6 and the tertiary windings 9, 10 respectively. One side terminals of the armatures 21, 22 of the 1st motor 25 and the 2nd motor 26 are connected to a DC terminal of a common rectifier 13 and the other side terminals of the armatures 21, 22 are connected to one side of DC terminals of rectifiers 11, 14 and the other side of the DC terminals of the rectifiers 11, 14 are connected to a DC terminal of a common rectifier 12. Then field coils 23, 24 of the repective motors are connected to DC terminals of rectifiers 17, 18. With above configuration the rectifiers can be used in common, so that the number of elements can be reduced. |
