Summary:The invention discloses a magnetic circuit decomposition type vernier permanent magnet motor, which belongs to the technical field of permanent magnet motors. The motor comprises a rotor and a statorwhich are arranged in a nested manner. The rotor comprises permanent magnets and a rotor magnetic core. The permanent magnets comprise magnetic steel units arranged along the axial direction of the rotor. The rotor magnetic core comprises an axial lamination and radial magnetic core. The axial lamination is formed by alternately arranging U-shaped laminations and linear laminations. A stator coreis of a toothed groove structure, and an armature winding is embedded into the toothed groove structure. The linear laminations of the rotor magnetic core are connected with the radial magnetic core by means of pasting or inserting. Each magnetic steel unit is a Halbach array comprising radial magnetizing magnetic steel and circumferential magnetizing magnetic steel. The armature magnetic field isweakened on the premise of
