<p><P>PROBLEM TO BE SOLVED: To provide a rotary electric machine system with flux shunt control which has good energy efficiency in a rotary electric machine with magnet excitation. <P>SOLUTION: A field part opposing an armature is divided into two so as to be relatively biasable, and the magnetic flux from a field magnet is shunted into a main magnetic path passing through an armature and a bypass magnetic path not passing through the armature in accordance with relative bias, thereby changing the field magnetic flux amount. A rotary electric machine system and a field control method capable of controlling magnetic field are obtained by suppressing a magnetic force impeding the biasing as minimum magnetic force conditions for setting the reluctance of the main and bypass magnetic paths to sustain the total amount of flux from the field magnet at a constant level or by using a magnetic force appearing without conforming to the minimum magnetic force conditions. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
