Abstract:
To provide a magnetic machine capable of reducing the ripple and cogging of torque or thrust. An electric motor 1 includes three stators 6 to 8 each having an armature row, a rotor 3 having a permanent magnet row, and a rotor 10 having a soft magnetic material row. The respective phases in electrical angle between magnetic poles generated at respective armatures 6a to 8a of 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 armatures 6a to 8a of the armature row and soft magnetic material cores 11b to 13b of the soft magnetic material row are set to be each displaced in the predetermined direction by an electrical angle of π/3.
