ABSTRACT:
In a magnet-exciting rotating electric machine system, every magnetic salient pole group to be magnetized in a same polarity is collectively magnetized by a magnetic excitation part. In the magnetic excitation part, a main magnetic flux path in which a magnetic flux circulates through the armature and a bypass magnetic flux path are connected to the field magnet in parallel. Magnetic flux amount in each path is controlled by mechanical displacement. Thereby, the rotating electric machine system and the magnetic flux amount control method in which magnetic field control is easy are provided. Also, means and method are provided so that a power required for the displacement may be made small by adjusting magnetic resistance of the above magnetic flux path.
