ABSTRACT:
In a rotary electric system, a rotary electric machine is provided with an armature core and star-connected multiphase windings with a neutral point wound in the armature core. Each of the star-connected multiphase windings has a predetermined winding configuration that prevents, when a zero-phase current is supplied from a direct current power source to the star-connected multiphase windings via the neutral point, a zero-phase magnetic flux created in the armature core based on the zero-phase current flowing in each phase winding of the star-connected multiphase windings from being cancelled out by a zero-phase magnetic flux created in the armature core based on the zero-phase current flowing in another one phase winding of the star-connected multiphase windings.
