ABSTRACT:
A rotary electric apparatus comprises a rotor including a first and second rotor members, a stator including a first stator and second stator members with armature coils to which armature current is supplied for synchronous rotation. The first and second rotor members are formed into a skewed type. Control means for controlling amounts Φ1and Φ2of field magnetic flux generated by the first and second rotor members, respectively, such that the amounts Φ1and Φ2differ from each other to reduce a difference between a maximum amplitude of a predetermined-order harmonic component F1of an electromagnetic force caused by a pair of the first rotor member and the first stator member and a maximum amplitude of the predetermined-order harmonic component F2of an electromagnetic force caused by a further pair of the second rotor member and the second stator member is reduced.
