A rotating electric machine system includes a rotor having a rotor plane. The rotor includes magnetic salient poles in a circumferential direction on the rotor plane. Adjacent magnetic salient poles are magnetized in different polarities from each other by a permanent magnet. A control magnet is arranged in an inside part of the adjacent magnetic salient poles. An excitation coil is placed so as to make an excitation flux collectively in the rotor. The magnetization state of the control magnet where the magnetic flux by the armature coils and the excitation flux flow in a same direction is changed irreversibly. An amount of the magnetic flux flowing through the armature coils is controlled by changing the magnetization state of the control magnet in accordance with an output of the rotating electric machine system so that the output is optimized.
