Abstract
An armature winding of a rotary electric machine includes two systems of electrically independent windings. An armature winding of a first system is closer to the field element in the radial direction than an armature winding of a second system, A current control device is provided for controlling a current to the armature winding of the first system and the armature winding of the second system. In consideration of a difference in magnetic flux waveforms from the field element caused by a difference in the distance to the field element in the radial direction, the current control device differentiates a current waveform to the armature winding of the first system from a current waveform to the armature winding of the second system.
