The suitable phase connecting mechanism, not shown, detects the current, frequency and phase induced in the coil 13 when becoming near the synchronizing speed, and fires the thyristor of the commutator 14. At this time, the armature coil 17 of the exciter 6 produces a high AC voltage, the exciting coil 5 and the armature coil 15 of the exciter 3 are sufficiently energized, the shortcircuit of the coil 13 of the motor 1 is released to flow a main machine exciting current, and synchronized with the synchronizing speed. In this manner, the exciting facility can be simplified to effectively reduce the cost.
