Beschreibung
Zusammenfassung:	A rotary machine includes two sets of three-phase stator winding wires and two sets of inverters connected to the same direct-current power supply. Alternating-current terminals of the inverters are respectively connected to the three-phase stator winding wires. Stator winding wires are housed in a plurality of slots to form a stator. The two sets of three-phase stator winding wires and the stator winding wires in the same phase of the sets are started to be wound from the slot positions, with phases thereof being different from each other by 180 degrees, among the plurality of slots and are finished being wound in the slot positions, with phases thereof different from each other by 180 degrees. Winding end points of the three-phase stator winding wires are respectively connected in common, and alternating-current voltages having the same magnitude and opposite phases are applied to the two sets of three-phase stator winding wire.
