description A drive system for a rotary machine includes a rotary machine including 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 two sets of inverters are respectively connected to the three-phase stator winding wires of the sets. In the rotary machine, stator winding wires are housed in a plurality of slots to form a stator, the two sets of three-phase stator winding wires are provided and the stator winding wires in the same phase of the sets are started to be wound from the slot positions, phases of electric angles of which are different from each other by 180 degrees, among the plurality of slots and finished being wound in the slot positions, phases of electric angles of which are different from each other by 180 degrees, winding end points of the three-phase stator winding wires of the sets 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.
