Abstract
To provide a magnetic machine capable of reducing the ripple and cogging of torque or thrust. An electric motorincludes three statorstoeach having an armature row, a rotorhaving a permanent magnet row, and a rotorhaving a soft magnetic material row. The respective phases in electrical angle between magnetic poles generated at respective armaturestoof the armature row and the magnetic poles of the permanent magnet row are set to be each displaced in a predetermined direction by an electrical angle of 2π/3, and the respective phases in electrical angle between the magnetic poles generated at the respective armaturestoof the armature row and soft magnetic material corestoof the soft magnetic material row are set to be each displaced in the predetermined direction by an electrical angle of π/3.
