    • PROBLEM TO BE SOLVED: To implement torque amplification while suppressing an inverse electromotive voltage generated in a winding, in a rotary electric machine system where torque can act between a first rotor and a second rotor and between a stator and the second rotor.SOLUTION: By controlling a d-axis current of a rotor winding 30 in such a manner that a d-axis magnetic flux of the rotor winding 30 weakens a field magnetic flux of a permanent magnet 33 flowing to an input-side rotor 28 and strengthens a field magnetic flux of the permanent magnet 33 flowing to a stator 16, while suppressing an inverse electromotive voltage of the rotor winding 30, torque between the stator 16 and an output-side rotor 18 is amplified. By controlling a d-axis current of a stator winding 20 in such a manner that a d-axis magnetic flux of the stator winding 20 weakens the field magnetic flux of the permanent magnet 33 flowing to the stator 16 and strengthens the field magnetic flux of the permanent magnet 33 flowing to the input-side rotor 28, while suppressing an inverse electromotive voltage of the stator winding 20, torque between the input-side rotor 28 and the output-side rotor 18 is amplified.
