Abstract:
1. A rotary electric apparatus, comprising: a rotation shaft having an axial direction about which the rotation shaft rotates; a rotor including a first rotor member and a second rotor member each generating magnetic flux providing a field and being secured at different positions along the axial direction of the rotation shaft; a stator facing the rotor with a predetermined-size air gap therebetween and including a first stator member and a second stator member each of which is equipped with armature coils through which armature current is supplied for synchronous rotation between the rotor and the stator; a skewing structure mutually skewing the first rotor member and the second rotor member such that a first phase angle θ a control structure that controls each of an amount Φ the rotor is composed of a magnet type of rotor provided with magnets generating the field magnetic flux, both the skewing structure and the control structure being arranged with the rotor, each magnet has a plate-like shape and is embedded in the rotor along the axial direction of the rotor having a cylindrical surface facing the stator, and the first rotor member is different in a width of each magnet from the second rotor member, the width of each magnet being defined as a width of a surface of each magnet, the surface facing a cylindrical surface of the rotor.
